DESCRIPTION

All operating power for the DPG1000L gauge is supplied by the 4-20 mA cur-

rent loop. The 2-wire connection allows the DPG1000L to be used as a digital

indicating transmitter in any 4-20 mA current loop application. The output is a

continuous analog signal based on the transducer output rather than the dis-

play. The output is filtered to improve noise immunity and has a response time

of about 50 msec. The temperature compensated piezoresistive transducer fea-

tures 316 stainless steel wetted parts.

The TEST pushbutton, when depressed, switches the display and output loop

to a preset level determined by the setting of a Test potentiometer.

INSTALLATION AND PRECAUTIONS

Install or remove gauge using wrench on hex fitting only. Do not attempt to tight-

en by turning housing or any other part of the gauge. Use fittings appropriate for

the pressure range of the gauge. Do not apply vacuum to gauges not designed

for vacuum operation. Due to the hardness of 316 stainless steel, it is recom-

mended that a thread sealant be used to ensure leak-free operation.

NEVER insert objects into the gauge port or blow out with compressed air.

Permanent damage not covered by warranty will result to the sensor.

ELECTRICAL CONNECTION

Connection to the DPG1000L is made with the 2-wire cable at the gauge rear.

Connect the loop (+) supply to the RED lead and the loop (–) supply to the

BLACK lead. Reversing the connections will not harm the gauge but the

DPG1000L will not operate with incorrect polarity.

LOOP VOLTAGE

Select a loop power supply voltage and total loop resistance so that when the

loop current is 20 mA, the gauge will have at least 8 VDC at its terminals. For

correct operation and to avoid erratic or erroneous readings, the gauge termi-

nal voltage must not fall below 8 VDC. Too large a loop resistance will cause

the gauge output to “limit” or saturate before reaching its full 20 mA output.

The minimum loop supply voltage may be calculated from the formula:

Vmin = 8V + (20mA x Total loop resistance)

If the terminal voltage of the

gauge falls below about 7.8

VDC, erratic operation may

occur. This is an indication

that the loop supply/resist-

ance may not allow ade-

quate headroom for reliable

operation. This should

never occur in normal use.

If it does, examine the loop

supply/resistance.

OPERATION

The DPG1000L is designed

for continuous operation.

Warm-up time is negligible.

The display will show the

system pressure or vacu-

um, and the loop current

also will be proportional to

the system pressure/vacuum;

4 mA = Zero or low end

20 mA = Span, full-scale or high end.

TEST BUTTON

When the front-panel TEST button is held depressed, the display and loop cur-

rent are switched, independent of the system pressure, to a test level deter-

mined by the setting of the Test potentiometer. This test mode will allow setup

and testing of the current loop by switching to this test level whenever desired

without having to alter the system pressure.

To set the test output level, see gauge label for location of Test potentiometer.

Press and hold the front-panel TEST button and adjust the Test potentiometer

to set the display and loop current to the desired test level.

CALIBRATION

See gauge label for location of individual controls to adjust the zero and span

of the display.

Gauge Reference – Units may be re-zeroed without affecting the span calibra-

tion. The gauge port must be open to the ambient with no pressure or vacuum

applied. Adjust the Zero control until the gauge reads zero with the minus (–)

sign occasionally flashing.

Span calibration should only be attempted if the user has access to a pressure

reference of known accuracy. The quality of the calibration is only as good as

the accuracy of the calibration equipment and ideally should be at least four

times the gauge accuracy. Zero calibration must be done before span calibra-

tion. Record readings at three to five points over the range of gauge and adjust

span control to minimize error and meet specifications.

Absolute Reference – Gauges require vacuum generation and atmospheric

pressure measurement equipment for accurate calibration and thus are more dif-

ficult to calibrate in the field. Gauges may be returned to Cecomp Electronics for

factory certified recalibration. NIST traceability is available.

The DPG1000L has internal controls to adjust the agreement between the dis-

played value and the 4-20 mA loop current. These are set at the factory and

should not normally be adjusted. If adjustment is necessary, consult factory.

Accurate pressure generation and measurement and current measurement

equipment are required to successfully complete this calibration.

DESCRIPTION

The F4L series is a versatile family of industrial pressure and vacuum gauges

featuring a rugged NEMA 4X case. This type of enclosure, when properly

installed, is suitable for indoor or outdoor non-hazardous locations and provides

a degree of protection against falling dirt, rain, sleet, snow, windblown dust,

splashing water, hose-directed water, corrosion and ice formation.

The F4L is a two-wire 4-20 mA loop-powered pressure transmitter with indica-

tion. All operating power is supplied by the 4-20 mA current loop. The 2-wire

connection allows the F4L to be used as a pressure transmitter in any 4-20 mA

current loop application where local indication is desirable.

INSTALLATION AND PRECAUTIONS

Install or remove gauge using wrench on hex fitting only. Do not tighten by turn-

ing housing or any other part of the gauge. Use fittings appropriate for the pres-

sure range of the gauge. Do not apply vacuum to gauges not designed for vac-

uum operation. Due to the hardness of 316 stainless steel, it is recommended

that a thread sealant be used to ensure leak-free operation. NEVER insert

objects into the gauge port or blow out with compressed air. Permanent damage

not covered by warranty will result to the sensor.

ELECTRICAL CONNECTION

Connection to the F4L is made with the 2-wire cable at the gauge rear. Connect

the loop positive (+) supply to the RED lead and the loop negative (–) supply to

the BLACK lead. Reversing the connections will not harm the gauge but the F4L

will not operate with incorrect polarity. NEVER connect the gauge wires to volt-

age greater than 32 VDC or damage not covered by warranty will result.

LOOP VOLTAGE

Select a loop power supply voltage and total loop resistance so that when the

loop current is 20 mA, the gauge will have at least 8 VDC at its terminals. For

correct operation and to avoid erratic or erroneous readings, the gauge termi-

nal voltage must not fall below 8 VDC. Too large a loop resistance will cause

the gauge output to “limit” or saturate before reaching its full 20 mA output. The

minimum loop supply voltage may be calculated from the formula:

Vmin = 8V + (20mA x Total loop resistance)

If the terminal voltage of the gauge falls below about 7.8 VDC erratic operation

may occur. This is an indication that the loop supply/resistance may not allow

adequate headroom for reliable operation. This should never occur in normal

use. If it does, examine the loop supply/resistance.

OPERATION

The F4L is designed for continuous operation. Warm-up time is negligible. The

display indication and the loop current will be proportional to the system pres-

sure/vacuum; 4 mA = Zero or low end, 20 mA = Span, full-scale or high end.

The output is a continuous analog signal based on the transducer output rather

than the display. The output is filtered to improve noise immunity and has a

response time of about 50 milliseconds.

TEST BUTTON

The TEST pushbutton on the front of the gauge, when depressed, switches the

display and output loop to a preset level determined by the setting of a Test

potentiometer. This test mode will allow setup and testing of the current loop by

switching to this test level whenever desired without having to alter the system

pressure.

To set the test output level, see gauge label for location of Test potentiometer.

Press and hold the front-panel TEST button and adjust the Test potentiometer

to set the display and loop current to the desired test level.

CALIBRATION

See gauge label for location of individual controls to adjust the zero and span

of the display.

GAUGE reference units may be re-zeroed without affecting the span calibration.

The gauge port must be open to the ambient with no pressure or vacuum

applied. Adjust the Zero control until the gauge reads zero with the minus (–)

sign occasionally flashing.

Span calibration should only be attempted if the user has access to a pressure

reference of known accuracy. The quality of the calibration is only as good as

the accuracy of the calibration equipment and ideally should be at least four

times the gauge accuracy. Zero calibration must be done before span calibra-

tion. Record readings at three to five points over the range of gauge and adjust

span control to minimize error and meet specifications.

ABSOLUTE reference gauges require vacuum generation and atmospheric

pressure measurement equipment for accurate calibration and thus are more dif-

ficult to calibrate in the field. Gauges may be returned to Cecomp Electronics for

factory certified recalibration. NIST traceability is available.

The F4L has internal controls to adjust the agreement between the displayed

value and the 4-20 mA loop current. These are set at the factory and should not

normally be adjusted. If adjustment is necessary, consult factory. Accurate

pressure generation and measurement and current measurement equipment

are required to successfully complete this calibration.

DESCRIPTION

All operating power for the F16L series is supplied by the 4-20 mA current loop. The

2-wire connection allows the F16L to be used as a digital indicating transmitter in any

4-20 mA current loop application. The output is a 12,000 count analog 4-20 mA sig-

nal. The output is filtered to improve noise immunity and is updated approximately 16

times per second. The temperature compensated piezoresistive transducer features

316 stainless steel wetted parts.

The TEST pushbutton, when depressed, switches the display and output loop to a

preset level determined by the keypad setting of the test value.

INSTALLATION AND PRECAUTIONS

Install or remove gauge using wrench on hex fitting only. Do not attempt to tighten by

turning housing or any other part of the gauge. Use fittings appropriate for the pres-

sure range of the gauge. Do not apply vacuum to gauges not designed for vacuum

operation. Due to the hardness of 316 stainless steel, it is recommended that a

thread sealant be used to ensure leak-free operation.

NEVER insert objects into the gauge port or blow out with compressed air.

Permanent damage not covered by warranty will result to the sensor.

ELECTRICAL CONNECTION

Connection to the F16L is made with the 2-wire cable at the gauge rear. Connect the

loop (+) supply to the RED lead and the loop (–) supply to the BLACK lead. Reversing

the connections will not harm the gauge but the F16L will not operate with incorrect

polarity.

LOOP VOLTAGE

Select a loop power supply voltage and total loop resistance so that when the loop

current is 20 mA, the gauge will have at least 8 VDC at its terminals. For correct oper-

ation and to avoid erratic or erroneous readings, the gauge terminal voltage must not

fall below 8 VDC. Too large a loop resistance will cause the gauge output to “limit” or

saturate before reaching its full 20 mA output.

The minimum loop supply voltage may be calculated from the formula:

Vmin = 8V + (20mA x Total loop resistance)

If the terminal voltage of the gauge falls below about 7.8 VDC, erratic operation may

occur. This is an indication that the loop supply/resistance may not allow adequate

headroom for reliable operation. This should never occur in normal use. If it does,

examine the loop supply/resistance.

OPERATION

The F16L is designed for continuous operation. Warm-up time is negligible. When

power is first applied, the F16L will set the loop current to maximum and check the

voltage available. If there is sufficient voltage available to power the unit, all active

segments will be displayed briefly.

Then the full scale pressure range and engineering units are displayed. All active

segments will again displayed briefly. Then the display will show the system pres-

sure, and the loop current will also be proportional to the pressure/vacuum. The out-

put is linearly proportional to the pressure.

Pressure, vacuum, or absolute ranges: 4 mA = Zero or low end

20 mA = Span, full-scale or high end

Bipolar ranges: 4 mA = negative or low end

12 mA = Zero

20 mA = Span, full-scale or high end

Compound ranges: 4 mA = negative or low end

(can be custom scaled by factory) 12 mA = midscale over entire range

20 mA = Span, full-scale or high end

At power-up, if the voltage available is not sufficient, only the low power segment will

be displayed. This is an indication that the loop impedance is too high or the loop

power supply voltage is too low. After successful power-up, if the loop voltage falls

below the minimum required for reliable operation, the F16L will continue to indicate

pressure with the low power segment blinking at a slow rate.

TEST BUTTON

When the front-panel TEST button is held depressed, the display and loop current

are switched, independent of the system pressure, to a test level determined by the

test setting. This test mode will allow setup and testing of the current loop by switch-

ing to this test level whenever desired without having to alter the system pressure.

To set the test output level, press and hold the front-panel TEST button and press

the up or down arrow buttons to adjust the test output to the desired pressure setting.

This setting is stored in non-volatile memory.

When the TEST button is held depressed, the display and loop current are switched,

independent of the actual pressure, to a level determined by the test setting. When

the button is released, normal operation is resumed.

CALIBRATION

The gauge is calibrated at the factory using equipment traceable to NIST. There is

no need to calibrate the gauge before putting it in service. Complete calibration

instructions can be downloaded from www.cecomp.com.

Calibration should only be performed by qualified individuals using appropriate cali-

bration standards and procedures. The calibration equipment should be at least four

times more accurate than the gauge being calibrated. The calibration system must

be able to generate and measure pressure/vacuum over the full range of the gauge.

A vacuum pump able to produce a vacuum of 10 microns (0.01 torr or 10 millitorr) or

lower is required for vacuum and absolute gauges.

The F16 series uses a user-modifiable calibration passcode to enter the calibration

mode. In the calibration mode, the gauge automatically recognizes the calibration

region corresponding to the applied pressure. There are 3, 4, or 5 calibration regions

depending upon the pressure range of the gauge. All gauges have Zero, +Midpoint,

and +Span regions. Gauges that measure vacuum as well as pressure will also have

a –Span region, and if the sensor is 15 psig or less, the gauge will have a –Midpoint

region as well.

Calibration of the loop output coordinates the 4-20 mA output to the display indica-

tion, and is performed independently of applied pressure. It requires a direct physical

measurement of the output. Calibration of the output coordinates the loop output to

the display indication, and normally does not need to be adjusted. This calibration

procedure can be downloaded from www.cecomp.com.

DPG1000DR Series Instructions

Cecomp maintains a constant effort to upgrade and improve its products. Specifications

are subject to change without notice. Consult factory for your specific requirements.

INSTALLATION AND PRECAUTIONS

Install or remove the gauge using wrench on hex fitting only. Do not attempt to tighten by

turning housing or any other part of the gauge. Use fittings appropriate for the pressure

range of the gauge. Do not apply vacuum to gauges not designed for vacuum operation.

Due to the hardness of 316 stainless steel, it is recommended that a thread sealant be used

to ensure leak-free operation. NEVER insert objects into the gauge port or blow out with

compressed air. Permanent damage not covered by warranty will result to the sensor.

NEVER connect the gauge wires directly to 115 VAC or permanent damage not covered

by warranty will result!

ELECTRICAL CONNECTION

The DPG1000DR series can be powered by any 9 to 32 VDC or 8 to 24 VAC 50/60 Hz

power source. An inexpensive unregulated low voltage source can be used. The magnitude

of the supply voltage has negligible effect on the gauge calibration as long as it is within the

stated voltage ranges. Do not allow the gauge supply voltage fall below 9 VDC or 8 VAC

RMS. Operation below these values may cause erratic or erroneous readings or output.

Models with 4-20 mA output power the current loop. Use a power source with sufficient volt-

age to operate the current loop.

Connection is made with the 4-conductor cable at the gauge rear. This cable accommo-

dates both the gauge power supply and retransmission output. If using a 9 to 32 VDC

power source, connect the (+) supply to the RED lead and the (–) supply to the BLACK

lead. If using a 8 to 24 VAC 50/60 Hz power source, connect to the RED and BLACK leads.

When using low voltage AC power, there is of course, no polarity consideration.

The (+) retransmission output appears on the WHITE lead, and the (–) retransmission out-

put appears on the GREEN lead. Use of the shield (drain) wire of the retransmission out-

put is optional. It is not generally needed for 4-20 mA current loops unless very long cable

lengths are used in electrically noisy environments.

Power – BLACK

Power + RED

Output – GREEN

Output + WHITE

The output is a continuous analog signal based on the transducer output rather than the

display. This output is filtered to improve noise immunity and has a response time of about

50 milliseconds.

The power supply (–) lead is tied to the retransmission output ground. Therefore, if a DC

supply is used, the power supply (–) lead should be considered common with regard to the

retransmission output (–) connection.

USING THE RETRANSMISSION OUTPUT

NEVER connect retransmission output wires together or to an external power source or

permanent damage not covered by warranty will result.

For 4-20 mA output models, be sure to observe the output compliance (voltage drive) capa-

bilities of the gauge. The compliance, and therefore the maximum loop resistance the out-

put can drive, is a function of the supply voltage to the gauge. Consult the graph shown

below for maximum loop resistance vs. gauge supply voltage. Too large a loop resistance

will cause the gauge output to “limit” or saturate before reaching its full 20 mA output.

When using the 0-2 volt retransmission output, do not allow the resistive load on the out-

put to fall below 5K ohms. Avoid large capacitive loads (greater that 1000 pF) such as those

caused by long runs of shielded cable. For long cable runs, use a 4-20 mA output model.

OPERATION

The gauge is powered on whenever a supply voltage is applied. Warm-up time is negligi-

ble. In normal operation, the system pressure is displayed on the LCD and an output sig-

nal will be present. DPG1000DRBL model display backlighting will be on whenever power

is on. The display backlighting will not be apparent under bright lighting conditions.

TEST BUTTON

When the front-panel TEST button is held depressed, the display and retransmission out-

put are switched, independent of the system pressure, to a test level determined by the set-

ting of the Test potentiometer. This test mode will allow setup and testing of the output and

any external device(s) connected to it by switching to this test level whenever desired with-

out having to alter the system pressure.

To set the test output level, see gauge label for location of Test potentiometer. Press and

hold the front-panel TEST button and adjust the Test potentiometer to set the display and

retransmitted output to the desired test level.

CALIBRATION

The gauge is calibrated at the factory using equipment traceable to NIST. There is no need

to calibrate the gauge before putting it in service. Complete calibration instructions can be

downloaded from www.cecomp.com. Gauges may be returned to Cecomp Electronics for

factory certified recalibration. NIST traceability is available.

Span calibration should only be attempted if the user has access to a pressure reference

of known accuracy. The quality of the calibration is only as good as the accuracy of the cal-

ibration equipment and ideally should be at least four times the gauge accuracy.

Absolute reference gauges require vacuum generation and atmospheric pressure meas-

urement equipment for accurate calibration and are more difficult to calibrate in the field.

The calibration system must be able to generate and measure pressure/vacuum over the

full range of the gauge. A vacuum pump able to produce a vacuum of 10 microns (0.01 torr

or 10 millitorr) or lower is required for vacuum and absolute gauges.

1. Low-voltage powered gauges must be connected to 8-24 VAC 50/60 Hz or 9-32 VDC

during the calibration procedure. The supply voltage has negligible effects on the gauge

calibration as long as it is within the stated voltage ranges.

2. Allow the gauge to equalize to normal room temperature before calibration.

3. Access the individual controls to adjust the zero and span of the display.

4. Zero calibration must be done before span calibration.

5. Zero for gauge reference pressure or vacuum gauges: Gauge reference units may

be re-zeroed without affecting the span calibration. The gauge port must be open to the

ambient with no pressure or vacuum applied. Adjust the Zero potentiometer for a display

indication of zero with the minus (–) sign occasionally flashing.

Zero for absolute reference gauges: Apply full vacuum to the gauge. Adjust the Zero

potentiometer for a display indication of zero with the minus (–) sign occasionally flashing.

6. Span for gauge reference pressure gauges and absolute reference gauges: Apply

full-scale pressure and adjust the Span potentiometer for a display indication equal to

full-scale pressure.

Span for gauge reference vacuum gauges: Apply full vacuum to the gauge. Adjust the

Span potentiometer for a display indication equal to full-scale vacuum.

7. Verify pressure indications at 0%, 25%, 50%, 75%, and 100% of full scale and repeat

calibration as needed to achieve best accuracy over desired operating range.

Calibration of the retransmission output coordinates the retransmission output to the dis-

play indication, and normally does not need to be adjusted. It requires a direct physical

measurement of the retransmission output. This calibration procedure can be downloaded

from www.cecomp.com.

INSTALLATION AND PRECAUTIONS

Install or remove the gauge using wrench on hex fitting only. Do not attempt to tighten by

turning housing or any other part of the gauge. Use fittings appropriate for the pressure

range of the gauge. Do not apply vacuum to gauges not designed for vacuum operation.

Due to the hardness of 316 stainless steel, it is recommended that a thread sealant be used

to ensure leak-free operation. NEVER insert objects into the gauge port or blow out with

compressed air. Permanent damage not covered by warranty will result to the sensor.

NEVER connect the gauge wires directly to 115 VAC or permanent damage not covered

by warranty will result!

ELECTRICAL CONNECTION

The F4DR series can be powered by any 9 to 32 VDC or 8 to 24 VAC 50/60 Hz power

source. An inexpensive unregulated low voltage source can be used. The magnitude of the

supply voltage has negligible effect on the gauge calibration as long as it is within the stat-

ed voltage ranges. Do not allow the gauge supply voltage fall below 9 VDC or 8 VAC RMS.

Operation below these values may cause erratic or erroneous readings or output. Models

with 4-20 mA output power the current loop. Use a power source with sufficient voltage to

operate the current loop.
