21 APPLICATIONS.
The TX200™ pressure transmitter is available as either a field adjustable
turndown (see Part II – Adjustments). Both models utilize a piezo-resistive
or bonded foil sensor technology to continuously monitor pressure in a sys-
tem. Changes in system pressure change the resistance in the sensor trans-
lating to either a 4-20 mA or voltage (VDC) output to a digital meter, gage,
PLC (programmable logic controller) or other device.

PROOF PRESSURE* LIMITS STATED IN THE LITERATURE
AND ON TRANSMITTER
HOUSING MUST NEVER BE EXCEEDED, EVEN BY SURGES IN THE SYS-
TEM. OCCASIONAL OPERATION OF UNIT UP TO MAXIMUM PRESSURE IS
ACCEPTABLE (E.G., START-UP, TESTING). CONTINUOUS OPERATION SHOULD NOT
EXCEED THE DESIGNATED OVER RANGE PRESSURE.
*Proof Pressure
The maximum pressure to which a pressure sensor may be occasionally
subjected, which causes no permanent damage (e.g., start-up, testing). The
units may require re-adjustment.
THESE PRODUCTS DO NOT HAVE ANY FIELD REPLACEABLE PARTS.
ANY SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR

IF SEVERE PRESSURE SURGES ARE EXPECTED, CONSIDER THE USE OF A
PRESSURE SNUBBER.
UNIT MAY BE MOUNTED IN ANY POSITION. ALWAYS HOLD A WRENCH

WIRING
DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING UNIT.
ELECTRICAL RATINGS STATED IN LITERATURE AND ON THE
TRANSMITTER MUST NOT BE EXCEEDED. FOR AMBIENT TEMPERA-
TURES BELOW -10°C AND ABOVE +60°C, USE FIELD WIRING SUITABLE FOR
BOTH MINIMUM AND MAXIMUM AMBIENT TEMPERATURE.
EXTERNAL GROUNDING SCREW (OPTION M460) IS REQUIRED FOR
NON-METALLIC CONDUIT SYSTEMS. (ATEX REQUIREMENT ONLY– SEE
FIGURE 2).
IN ORDER TO MEET EUROPEAN EMC REQUIREMENTS, THE TX200™
WIRING MUST BE INSTALLED IN A GROUNDED METAL CONDUIT OR
WITH OTHER SUITABLE SHIELDING.
THE TX200™ TRANSMITTER ACCEPTS 10-36 VDC FOR 4-20 MA
OUTPUT UNITS AND 10-30 VDC FOR VOLTAGE (VDC) OUTPUT UNITS.
THE SUPPLY VOLTAGE SHALL NOT EXCEED 36 VDC FOR 4-20 MA
OUTPUT UNITS AND 30 VDC FOR VOLTAGE (VDC) OUTPUT UNITS. THE

Part II - Adjustments
SPANNING THE TX200A™ TRANSMITTER USING THE
SHUNT CAL. FEATURE
calibration feature (see figure 3). No pressure source is required for this process.
Example: A 1,000 psi range TX200A can be adjusted for any range between 0 to 200 psi
and 0 to 1,000 psi.
Use the formula below to calculate lcal or Vcal. This number represents the output
current or voltage that the user will set with the shunt cal. on in order to achieve
the desired range.
4-20 mA models formula: Ical = (Cal# x 16mA/Pcal) + 4mA
Voltage out (VDC) models formula: Vcal = (Cal# x VFSO/Pcal) + Vzero
Ical is the output current that the user will set, with the shunt cal on to achieve
the desired full scale pressure range (Pcal)
Vcal is the output voltage that the user will set, with the shunt cal on to achieve
the desired full scale pressure range (Pcal)
Cal# is the amount of pressure simulated by turning the shunt cal on. The
Cal# is engraved on the TX200A housing and written on the Certificate of
Calibration.
Pcal is the full scale pressure range the user is adjusting to.
Vzero is the output of the voltage (VDC) out model with no pressure applied.
VFSO is the full scale output, in volts, of a voltage (VDC) out model.
Example: For a TX200A with a 1-5 Volt output: Vzero = 1 volt and VFSO = 4 volts
Procedure:
1. Determine the desired pressure range
2. Calculate Ical for 4-20mA models or Vcal for voltage (VDC) models using
the formulae above.
3. Power the TX200 with a suitable power supply.
a. 4-20mA models can be powered with a 24VDC power supply
represents the current in the loop. 100mV = 1mA.
b. Voltage (VDC) out models can be connected directly to a 24V
power supply. The output voltage is measured between the Blue
(+) and Black (–) wires.
Please refer to figure 3 for steps 4-7.
4. Adjust the Zero as necessary.
6. Adjust the Span and Fine Span controls until the output reaches the Ical
or Vcal number calculated in step 2.
Example:
- this is the Pcal. The Cal#
formula above, IcalIcal
completed, the transmitter in this example would be spanned so that the 4 mA output signal = 0

RECOMMENDED PRACTICES AND WARNINGS
United Electric Controls Company recommends careful consideration of the fol-
lowing factors when specifying and installing UE pressure and temperature units.
Before installing a unit, the Installation and Maintenance instructions provided
with unit must be read and understood.
• Toavoiddamagingunit,proofpressureandmaximumtemperaturelimitsstated
in literature and on nameplates must never be exceeded, even by surges in the
system. Operation of the unit up to maximum pressure or temperature is accept-
able on a limited basis (e.g., start-up, testing) but continuous operation must be
restricted to the designated adjustable range. Excessive cycling at maximum
pressure or temperature limits could reduce sensor life.
• Aback-upunitisnecessaryforapplicationswheredamagetoaprimaryunit
could endanger life, limb or property. A high or low limit switch is necessary
for applications where a dangerous runaway condition could result.
• Theadjustablerangemustbeselectedsothatincorrect,inadvertentormali-
cious setting at any range point cannot result in an unsafe system condition.
• Install unit where shock, vibration and ambient temperature fluctuations will
not damage unit or affect operation. When applicable, orient unit so that
moisture does not enter the enclosure via the electrical connection. When
appropriate, this entry point should be sealed to prevent moisture entry.
• Unitmustnotbealteredormodifiedaftershipment.ConsultUEifmodifica-
tion is necessary.
• Monitoroperationtoobservewarningsignsofpossibledamagetounit,such
as drift in set point or faulty display. Check unit immediately.
• Preventativemaintenanceandperiodictestingisnecessaryforcriticalappli-
cations where damage could endanger property or personnel.
•Electrical ratings stated in literature and on nameplate must not be exceed-
ed. Overload on a switch can cause damage, even on the first cycle. Wire
unit according to local and national electrical codes, using wire size recom-
mended in installation sheet.
• Donotmountunitinambienttemp.exceedingpublishedlimits.
