6. MEASUREMENT PRINCIPLES AND CONSTRUCTION
6.1. Measurement Principles, Electronic System.
Differential pressure transmitters work by converting changes in the resistance of a ceramic sensor, which are
proportional to the measured differential pressure, into a standard current signal. The active sensing element is
a ceramic sensor.
A transmitter block diagram is presented in Figure 1. At the circuit input two analogue signals are provide: the
measured pressure reflecting and the sensing module temperature. These signals are digitalized and provide to
a microprocessor input which controls the transmitter’s operation. Using input data during the production
process adjusts for thermal errors and carries out linearization. After digital processing, the signal is converted
into an analogue 4÷20mA current signal again, with a superimposed Hart signal.
For communication with the transmitter via the signal line an Aplisens KAP communicator, or a computer
meeting the requirements given in 10.2.4, are used.
The transmitter’s output is fitted with a radio-noise filter and other elements protecting against EM.

6.2. Construction.
The basic units of transmitter are: casing, pressure sensor, processing unit with local LCD display, as well as
anti-noise filter.
6.2.1. Casing
The casing of APRE-2000GN transmitter is made with polycarbonate (PC) or with akrylonitrylo-butadieno-styren
(ABS) and it consists with the case as well as the transparent cover.
6.2.2. Processing unit
6.2.2.1. The processing module consists from the main plate of electronics with LCD display, as well as the
plate of A/C converter.
6.2.2.2. The ceramic pressure sensor is closed in the plastic case equipped in the pressure connections as
well as the electrical exit terminals.
7. PLACE OF INSTALLATION
7.1. General recommendations
7.1.1. The transmitters can be installed both indoors and outdoors. It is recommended that transmitters intended
for outdoor use be placed in a box or under cover.
7.1.2. The place of installation should be chosen in a such way as to allow a good access to the device and to
protect its from mechanical damage. In planning the installation of the transmitter and configuration of the
impulse lines, attention should be paid to the following requirements:
The impulse lines should be as short as possible, with a sufficiently large cross-section, and free of
sharp bends, in order to prevent blockages;
The transmitters should be installed above the measuring point, so that condensation flows down towards
the site of the pressure measurement.
The impulse lines should be inclined at a gradient of at least 10cm/m;
The configuration of the impulse lines and the valve connection system should be chosen with
regard to the measurement conditions and to requirements such as the need to reset the
transmitters in position and the need for access to the impulse lines.
7.1.3. Should also be paid attention to possible installation faults which may lead to measurement errors, such as
connections which are not tight, sediment blockage in lines which are too narrow, liquid column in a gas line etc.
7.2. Low Ambient Temperature.
Thermal insulation can protect the transmitter casing and lines only from brief exposure to low
temperatures.
7.3. Mechanical Vibration, Corrosive Media.
7.3.1. The transmitter should be installed in a place which is free of vibrations. If vibrations are carried to the
transmitter via the impulse lines, use should be made of elastic lines.
7.3.2. Avoid the installing of transmitters in the places of appearance the heavy objects hitting.
8. INSTALLATION AND MECHANICAL CONNECTIONS
8.1. Installation and connections
8.1.1. The APRE-2000GN transmitter can be mounted on a wall or on a control panel. The transmitter is fitted
with connectors which fit to an Ø6x1 elastic impulse tube. When the measuring impulse is transmitted via a
metal terminal with M20x1.5 connector, an adapter is used between the M20x1.5 thread and the Ø6x1 terminal.
Transmitters should be installed in a vertical position. The way of impulse line leading should enable the
vapour flowing towards the place of instalation (pipeline). Where there is a significant difference between the
height at which the transmitter is mounted and the height of the impulse source, particularly if the measurement
range is small, the reading may fluctuate depending on the temperature difference between the impulse lines.
This effect can be reduced by ensuring that the impulse lines run side by side.
To equipment completing in assembling of transmitters, will be helpful the information about connecting
pressure elements such as: reductive, nests, valves, reductive yokes, signal tubes. Data on this subject are
contained in APLISENS catalogue.

A 6 DTR.APREGN.01(ENG)
9. ELECTRICAL CONNECTION
9.1. General recommendations
9.1.1. It is recommended that twisted pair cabling be used for the signal lines. If the transmitter and signal line
are subject to a large amount of electromagnetic interference, then shield pair cable should be used. The signal
lines should not run alongside network power supply cables or near to large electrically-powered devices.
The devices used together with the transmitters should be resistant to electromagnetic interference from the
transmission line in accordance with compatibility requirements.
9.1.2. Wet or rising damp inside transmitter can cause its damage.
When the cables isolation in the packing gland is ineffective (for example, when single wire
cables are used) the opening of the gland should be carefully sealed with an elastic sealing
compound to obtain IP65 protection. It is useful to form the segment of the signal wire leading
to the packing gland into a protective loop to prevent condensation from running down in the
direction of the gland.
9.2. Electrical connections
The APRE-2000GN transmitters are to be connected as shown in fig. 2.
9.3. Protection from excess voltage
9.3.1.Transmitters can be in danger from excess voltage caused by connection faults or atmospheric electrical
discharge. Protection from excess voltage between transmission line cables is provided by TVS diodes
assembled in anti-noise filter.
For long lines is profitably apply a protective device external for example one protection near transmitter (or inside the
transmitter), and second near entries to co-operating devices.
10. SETTING AND REGULATION
APRE-2000GN transmitters are factory calibrated to the range stated in the order or to the basic range.
After installation, the transmitter’s zero-point may move and require adjustment. This applies particularly where
the measurement range is small.
10.1. Transmitter Range. Basic Range. Definitions
10.1.1. The maximum range of pressure, or differential pressure, which the transmitter can measure is called
the “basic range” (for specifications of basic ranges see section 5.4.1).
The width of the basic range is the difference between the upper and lower limits of the basic range.
The internal characteristic conversion curve for the basic range is coded in the transmitter’s memory.
This is the reference curve used when making any adjustments which affect the transmitter’s output signal.
10.1.2. When the transmitter is in use the term “set range” is used. The set range is the range whose lower
end-point corresponds to an output current of 4mA and whose upper end-point corresponds to a current of
20mA (or 20mA and 4mA respectively when the conversion curve is inverted).
The set range may cover the whole of the basic range or only a part of it.
The width of the set range is the difference between its upper and lower end-points.
The transmitter may be set to any range within the basic range of pressure values, subject to the restrictions set
out in the table in section 5.4.1.
10.2. Configuration and Calibration
10.2.1. The transmitter has features which enable metrological and identification parameters to be set and
altered. The configurable metrological parameters affecting the transmitter’s output current include the
following:
a) Unit in which the measured pressure is expressed on the display;
b) Upper end-point of the set range;
c) Lower end-point of the set range;
d) Time constant;
e) Type of characteristic curve: linear or radical.
i
i

A 7 DTR.APREGN.01(ENG)
Parameters of an informational nature which cannot be altered include the following:
f) Upper limit of the basic range;
g) Lower limit of the basic range;
h) Minimum range.
10.2.2. Other identification parameters, not affecting the output signal, include: device address, device type
code, factory identification code, factory device code, number of preambles (3÷20), UCS, TSD, program
version, electronics version, flags, serial number, label tag, description tag, date tag, message, record number,
sensing module number.
The process of setting the parameters listed in 10.2.1 and 10.2.2 is called “Configuration”.
10.2.3. It is possible to carry out a “pressure zeroing” procedure, for example to compensate for
measurement deviation caused by a change in position during the transmitter installation.
The transmitter may also be calibrated, by taking readings with the input pressure controlled using a standard
device. These process and zero-point adjustments are called “Calibration”.
10.2.4. Configuration and Calibration of the transmitter are carried out using an Aplisens KAP communicator,
certain Hart communicators or a PC with Hart/RS232 converter and Aplisens Raport 2 software.
Together with the “RAPORT 2” configuration software there is an „INTERVAL LINEARIZATION” software
supplied to enable the input of 21-point nonlinear functional characteristics to the transmitter.
A description of the functions of the KAP communicator is contained in the KAP Communicator Operating
Manual, and information on the Hart/RS232 converter can be found on the Hart/RS232/01 Converter
information sheet.
10.2.5. Local configuration of transmitters
If the option of local configuration is active, operator can change transmitter set using buttons being below
display. The access to buttons will get after unscrewing the side cover. Then we can also change the display
position turning it with 90ºangle position (see fig. 4).
If the option of local configuration is active, operator can change transmitter set using buttons being below
display. To enter at the local set change of the work mode, you should press one button and hold its about 4s. If
using buttons can't change the transmitter configuration, the local transmitter configuration is switched of and to
its switching on is necessary to use the KAP 3 Calibrator.
The buttons are signed with symbols: [↑] [↓] [◙]
After pressing by 4 seconds any of buttons there will appear on display “EXIT”.
If we will confirm this announcement across pressing and holding button [◙] by 1 sec, we will go out from the
local change of the MENU set. If we will not confirm, we can move in MENU and change interesting us
parameters. The time of pressing [↑] [↓] [◙] has to be longer than 1s.

MENU are possible using buttons or remote way using communicator, or the PC software. If it is necessary the
display switching off is also possible. The display switching of function is possible with using communicator or
PC software only.
The APRE-2000GN transmitter display exterior is as bellow.
There 3 main displays are visible:
Bargraf (display line) –the current output grade line guidance display. At 0% output guidance, the line
units are not blacked. As the guidance is rise the next units will blacked. One unit correspond to 10%
guidance. At 100% guidance all line units will blacked.
LCD1 –the current or guidance percent preset range display. In accordance with display configuration the
current value in 4 -20mA current loop, or percent guidance preset range is possible to display. When
current is displayed, symbol „c” before value is visible.
LCD2 –the measured pressure digital value display; the calibrated pressure value according to user’s
units display; the process variable units or user’s units display; the MENU announcement and other
information or warning announcement display.
In the case the digital pressure value or the calibrated pressure value display, the sign „–„ can be visible
before displayed value. The decimal point position is possible to set in local MENU or remotely.
In the case of display overfilling (when the displayed value will exceed the „99999”) the „COMMA”
displays. When the pressure value limits will exceeded the „ UNDER „ or „ OVER „are displayed
depending on exceeding direction. The pressure unit or user’s unit can be displayed alternating with digital
value displaying in 10s indicate digital value cycle, or 1s indicate digital value cycle. If it is necessary the
display unit switching off in local MENU is possible, or with communicator, or PC software using.
The transmitter makes possible rescale on the user's individual the pressure value. To make this is
necessary with using communicator or PC software write the corresponding to beginning and to end
values of setting range as well as write the own unit name. After activating user's mode the rescale value
will be visible on display.
Local display is equipped in backlight, switching on and switching off with jumper on electronic board.

11. INSPECTIONS AND SPARE PARTS.
11.1. Periodic inspections
Periodic inspections should be made in accordance with the regulations to which the user is subject. During
inspection, the pressure connectors should be checked for loose connections and leaks, the electrical
connectors should be checked with regard to tightness and the state of the gaskets, packing glands, and the
diaphragm seals should be checked for tarnishing and corrosion.
Check the characteristic conversion curve by following the procedures for “Calibration” and, where appropriate,
“Configuration”.
11.2. Unscheduled inspections
If the transmitters are installed in a location where they may be exposed to mechanical damage, excess
pressure, excess voltage, or the diaphragm may be in danger from sedimentation, crystallization or
erosion, inspections should be carried out as required.
Where it is found that the signal in the transmission line is absent or its value is incorrect, a check should
be made on the line and its terminal connections.
Check whether the values of the supply voltage and load resistance are correct.
If a communicator is connected to the transmitter power supply line, a fault in the line may be indicated by
the message “No response” or “Check connection”. If the line is in order, check the operation of the
transmitter.
11.3. Overloading Damage
11.3.1. Sometimes transmitters malfunction due to diaphragm damages caused by overloading. Usually in such
cases the symptoms are such that the output current falls below 4mA or rises above 20mA, and the transmitter
fails to respond to input pressure. Then is necessary to change sensor.
12. PACKING, STORAGE AND TRANSPORT
The transmitters should be packed singly or in sets, in such a way as to protect them from damage during
transportation.
The transmitters should be stored in multiple packs under cover, in a place free of vapours and reactive
substances, with an air temperature between +5°C and +40°C, and relative humidity of not more than 85%.
During transportation, the transmitters should be packed and secured so as to prevent them from shifting.
Any means of transport may be used, provided direct atmospheric effects are eliminated.
13. GUARANTEE
The manufacturer guarantees the proper operation of the transmitters for a period of 24 months from the date of
purchase and servicing provided under the guarantee and following the guarantee period. In the case of special
versions, the guarantee period shall be agreed by the manufacturer and the user, but shall not be less than 12
months.
14. ADDITIONAL INFORMATION
The manufacturer reserves the right to make constructional and technological changes which do not lower the
quality of the transmitters.

Communicator or converter electrical connections to transmitter measuring lines.
For successful communication with transmitter the resistance in measuring loop, behind connected
device to communication, should be higher than 250Ω. If necessary install the additional resistor in the
line. The communicator or converter connecting ways to the measuring loop are presented at diagrams.
During increasing of resistance in the measure loop at making the good transmission, is necessary to
make sure that the tension falls at sum resistances in the loop don't lower minimum tension at transmitter
terminals. (see p.5.1.)
