6. CONSTRUCTION,PRESSURECONNECTORS,ELECTRICAL CONNECTORS
6.1. Measurement Principles, Electronic System
APCE... electronic pressure transmitters and APRE... electronic differential pressure transmitters work by
converting changes in the resistance of a piezoresistance bridge, which are proportional to the pressure
difference being measured, into a standard current signal.
The active sensing element is a silicon diaphragm with four (bridge) piezoresistors, separated from the medium
by a sealing diaphragm and manometric fluid.
The electronic system digitally processes the measurement signal and generates output signals: an analogue:
4÷20 mA signal, and a digital HART communication signal.
A transmitter electrical block diagram is presented in Figure 1. On the input circuit two analogue signals are
formed, reflecting the measured pressure and the sensing module temperature. These signals are digitized and
imputed to a microprocessor. Using data input during the production process adjusts for thermal errors and
carries out linearization.
After processing, the digital signal is converted into an analogue 4÷20mA current signal, with a superimposed
digital communication signal.
For communication with the transmitter via analog signal line the Aplisens KAP communicator, or a PC
computer meeting the requirements given in 10.2.4, is used.
The transmitter’s input point is fitted with a noise filter and elements protecting against excess voltage.
Plasma surge arrester is installed in the special Exi version on request. The transmitter then has got, on rating
plate, marking "Version SA".
6.2. Construction
The main components of the smart pressure transmitter is the sensing module, in which the pressure signal is
converted into an electrical signal, and the electronic system, which converts the signal from the sensing
module into a 4...20mA output analog signal and produces a digital HART signal.
6.2.1. To the APCE-2000, sensing module transmitters may be installed the pressure connectors as in figures
5a, 6a, 7a, 8 or other. They are equipped with a diaphragm separating the internal part of the head from the
medium.
6.2.2. In the APRE–2000 transmitters, the sensing module has two kind of process connectors: P-type
connectors (figure 9), or C-type with covers connecting for installation on a valve manifold (figure 10).
6.2.3. The APRE–2000 transmitters may be fitted with a single direct diaphragm seal, mounted on the “+”
pressure input of the sensing module, while the “–” input is a ¼NPT socket (figure 11).
The APRE–2000 transmitter is fitted with two diaphragm seals and can be produced in two versions:
- with one direct diaphragm seal and one remote diaphragm seal (figure 13);
- with two remote diaphragm seals (figure 12).
The diaphragm seal transmits the pressure obtained from the medium. The pressure is transmitted via a
manometric fluid which fills the space between the diaphragm of the seal and the diaphragm of the sensing
module. In the case of remote diaphragm seals, pressure is transmitted via a capillary linking the transmitter’s
sensing module to the diaphragm seal.
The construction of the seals depends on the medium properties and operating conditions for which they are
intended.
Technical data relating to the diaphragm seals’ dimensions and operating conditions can be found in catalogue
cards “DIAPHRAGM SEALS”.
6.2.4. The APRE-2000G are designed to the low pressures measurement of non-aggressive gases, with
a permitted overpressure of 350mbar or 1bar. The basic (economy) version of this transmitter has terminals
fitting ø6x1 elastic tubes, while the industrial version has adapters as shown in figure 14.

D5 12 DTR.APCE.APRE.02(ENG)
6.3. Casing, Electrical Connections
APCE..., APRE... transmitters are cased in an Ø51 pipe with a PD (DIN 43650) or PZ type connector.
6.3.1. The PD type connector (figure 3) is located on the top of the casing (Ø51 pipe) and sealed with a rubber
washer.
6.3.2. Transmitters with a PZ type connector (figure 4) have a terminal box connected permanently to the
casing. The box is closed with a lid and has an external and internal earthing terminal. Mounted on the inside
a terminal block is equipped with additional control terminals, galvanically connected to terminals 1, 2 and 3.
7. PLACE OF INSTALLATION OF TRANSMITTERS
7.1. General recommendations
7.1.1. The pressure transmitters and differential pressure transmitter can be installed both indoors and
outdoors. It is recommended that transmitters installed outdoor should be placed in a box or under cover. There
is no need for a cover in the case of transmitters with PZ type electrical connector.
7.1.2. The place of installation should be chosen in such a way as to allow access to the device and to protect it
from mechanical damage. In planning the transmitter installation and the pulse lines configuration, should be
paid attention 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.
- Where the medium is a gas, the transmitters should be installed above the measuring point, so that
condensation flows down towards the site of the pressure measurement; where the medium is a
liquid or where a protective liquid is used, the transmitters should be installed below the place where
the pressure measurement is taken.
- The impulse lines should be inclined at a gradient of at least 10cm/m.
- The levels of filling liquid in the impulse lines should be equal or kept constant difference.
- 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 during water or gas removal and flushing.
7.1.3. Where there is a risk of heavy objects hitting the instrument (resulting, in extreme cases,
in a part of the system with transducers being torn off and medium leakage), appropriate means
of protection should be applied for safety reasons and to avoid the possibility of sparkling or
other, more appropriate location should be selected for the transmitter.
7.1.4. Attention should also be paid 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, gas bubbles in a liquid line
or liquid column in a gas line etc.
7.2. Low Ambient Temperature
When the solidification point of the liquid whose pressure is being measured is greater than the
ambient temperature, steps should be taken to protect the measurement apparatus from
freezing effects.
This is particularly important in the case open-air installations.
Protection is obtained by filling the impulse lines with a mixture of ethylene glycol and water, or another liquid
whose solidification point does not exceed the ambient temperature. Thermal insulation can protect the casing
of the transmitter and lines only from brief exposure to low temperatures. Where the temperature is very low,
the transmitter and impulse lines are should be heated.
7.3. High Medium Temperature
The APCE..., APRE... transmitters may be used to measure media with temperatures of up to 120ºC.
To protect the sensing module from temperatures in excess of 120ºC, suitably long impulse lines are used to
disperse the heat and to lower the temperature of the module.
Where it is not possible to use impulse lines of the required length, APCE..., APRE... transmitters with remote
diaphragm seals should be used (see catalogue cards “DIAPHRAGM SEALS”).
Temperature applications for Ex versions in accordance with Appendix Ex.02.
i

D5 13 DTR.APCE.APRE.02(ENG)
7.4 Electrostatic hazards
Plastic rating plate and teflon on the diaphragm seals are non-conductive layer applied on conductive surface.
Transmitters in this version should be installed in locations with no possibility of electrostatic charging.
In particular through contact with electrified dust falling or exhaled from devices operating nearby.
For Exi version are valid data by Appendix Ex.02.
7.5. Mechanical Vibration, Corrosive Media
7.5.1. Transmitters should correctly work with vibrations with amplitudes to 1.6 mm and accelerations to 4g.
If strong vibrations are carried via the pressure line and disturb of measuring, use should be made of elastic
pulse lines or transmitters with a remote diaphragm seal.
7.5.2. Transmitters should not be installed in places where the diaphragm, made of 1.4404/1.4435
(316L) steel, would be subject to corrosion by the medium being measured.
If possible, transmitters with diaphragms made of Hastelloy C276 should be used, or other means of
protection applied (e.g. in the form of a separating liquid) or transmitters with diaphragm seals adapted
for measuring aggressive mediums according to catalogue cards “DIAPHRAGM SEALS”) should be used.
8. INSTALLATION AND MECHANICAL CONNECTIONS
APCE-2000 pressure transmitter with measuring ranges -7÷7 mbar and -25÷25 mbar
and APRE-2000G differential pressure transmitters should be mounted in a vertical position
with the process connectors downwards.
Others APCE..., APRE... transmitters can operate in any position.
When installed on an object with a high-temperature medium, it is advantageous to mount the transmitter in a
horizontal position with the packing gland pointing downwards or to the side, in such a way that the transmitter
is kept away from the stream of rising hot air.
When the measurement range is small, the reading can be affected by the position of the transmitter and by the
configuration of the impulse lines and the way in which they are filled with liquid.
This error can be corrected using the zero-setting function after transmitter installation.
8.1. APCE... Installation and connections
8.1.1. The APCE... transmitters can be installed directly on rigid impulse lines.
Where connectors are used as in figures 5a, 6a and 7a, it is recommended that connection sockets be used as
shown in figure 5b, 6b, 7b or 7c.
It is recommended that sockets labelled “Socket CG1” and “Socket CG1/2” Fig. 8 are used for CG1 and CG1/2
connections, respectively.
Besides, there are adapters for standard DIN50, (DIN40, DIN25, Clamp2”, Clamp1.5”, Clamp1”) type connections
provided for readouts carried out in aseptic conditions using transmitters with CM30x2 connection.
There are seals provided for every transmitter with P, CM30x2, CG1, CG1/2 and GP type connections.
The seal material is selected based on the pressure value and the type and temperature of the medium.
8.1.2. If the pressure is applied via a flexible plastic tube, the transmitter should be mounted on a support with
Red Ø6-M reduction. In case of metal pipes, the used connections should comply with PN-82/M-42306.
The types of the impulse tubes (Fig. 15) are to be selected depending on the measured value of the pressure
and the medium temperature.
8.1.3. Tighten the transmitter in the socket with a torque appropriate for the type of the used seal and the
measured pressure.
8.2. APRE... Installation and connections
8.2.1. The APRE 2000 transmitters can be mounted directly on rigid impulse lines.
To connect the transmitters basic versions, with two M20x1.5 stubs (P-type connector), can be use straight
connecting elements with nuts (type C). If elastic impulse lines are used for connection purposes, the
transmitter should be additionally fastened to a pipe, panel or supporting construction.
8.2.2. The APRE-2000 can be installed using the fastener ø25 (figure 16.) on an ø25 pipe or on a flat surface
using an angle bracket.

D5 14 DTR.APCE.APRE.02(ENG)
8.2.3. The APRE-2000 with connecting cover (C-type connector) (figure 10) are designed for installation on
3-valve or 5-valve manifolds to a 2” pipe or to a flat surface using an fastener C-2” (fig.17) or “U” (fig.18).
It is not permitted to unscrew the screws fixing the C type connection covers.
Interference will result in loss of warranty.
8.3. APRE-2000G. Installation and connections
8.3.1. The “economy” version of the APRE-2000G transmitter can be mounted on a wall, panel or other stable
construction, using a clamp with Ø9 holes (Figure 14).
The transmitter is fitted with stubs which fits an Ø6x1 elastic impulse tube.
When the measured impulse is transmitted via a metal terminal with M20x1.5 opening, an adapter is used
between the M20x1.5 thread and the Ø6x1 terminal.
Transmitters should be installed in a vertical position.
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 lines run side by side.
The APRE-2000G transmitter can also be fitted with an adapter (Figure 14) creating a C-type connector,
designed for installation on a 3-valve or 5-valve manifold. Aplisens can also supply transmitters ready mounted
on valves.
Pressure may be transmitted to the installed device only after checking that it has a
measurement range which properly corresponds to the value of the measured pressure, that
gaskets have been properly selected and fitted, and the connector has been properly screwed
tight.
Attempts to undo the screws or fixing connector pipes on a transmitter under pressure may
cause the medium to leak and create hazards for the personnel.
When disassembling the transmitter, it is necessary to disconnect it from the process pressure
or bring the pressure to atmospheric level, and to take particular care and precautions in case
of media which are highly reactive, caustic, explosive or otherwise hazardous to personnel.
If necessary, rinse out this part of the system.
Transmitters with flange diaphragm seals are to be installed on the corresponding counter flanges on
the facility.
It is recommended that the user matches the screw joints material to the pressure, temperature, flange
material and seal to ensure tightness of the flange joint in the expected operating conditions.
Coarse-threaded screws complying with ISO 261 are to be used for flanges used in the APCE...,
APRE... transmitters.
Additional data concerning the diaphragm seals are specified in the catalogue cards “DIAPHRAGM SEALS”.

D5 15 DTR.APCE.APRE.02(ENG)
9. ELECTRICAL CONNECTION
9.1. General recommendations
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 screened twisted pair cable should be used.
The signal wires 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.
It is also beneficial to use anti-interference filters on the primary side of the transformers, the power supplies
used for the transmitters and apparatus used in conjunction with them.
9.2. Connections for transmitters with PD-type connector
The transmitters with PD type connectors are to be connected as shown in figure 2a.
To make the connections, remove the terminal block from the contact pins together with its cover.
Then remove the block from its cover, levering it off with the end of a screwdriver inserted into the slot provided
for this purpose. Connect the wires to the block.
Where the isolation of the wires in the cable gland is ineffective (for example, when single wires are used)
the opening of the gland should be carefully sealed with an elastic sealing compound to obtain IP65
ingress protection. It is useful to form the segment of the signal wire leading to the PG-11, PG-9 cable
gland into a protective loop to prevent condensation from running down in the direction of the gland.
9.3. Connections for transmitters with terminal box (PZ-type connector)
The transmitters with PZ-type connectors should be connected by linking the signal wires to a terminal block, as
shown in figure 2a and 2b. Carefully screw in the cover and cork of the packing gland, making sure that the wire
is tightly packed. Where necessary, the packing gland should be further sealed as described in 9.2.
9.4. Protection from excess voltage
9.4.1. The transmitters may be in danger from excess voltage caused by connection faults or atmospheric
electrical discharge. Protection from excess voltage between the wires of the transmission line is provided by
TVS diodes installed in all types of transmitter (see the table, column 2).
9.4.2. In order to protect against excess voltage between the transmission line and the casing or earth (not
prevented by the diodes connected between the transmission wires), additional protection is provided in the
form of plasma surge arresters or TVS diodes (see the table, column 3).
In the case of unprotected transmitters, external protective devices may be used, e.g. the UZ-2 system
produced by Aplisens, or others. When the transmission lines are long, it is advantageous to use one
protective device near the transmitter (or inside it), and another near entry points to other devices used in
conjunction with it.
Internal protection of transmitters:
9.4.3. The voltage in the protective elements must not exceed the maximum permitted values given in columns
2 and 3 of the table.
The insulation test voltages (500V AC or 750V DC) given in 5.1.1 refer to transmitters without plasma
surge arresters - such protection is not used in Ex versions of transmitters.
9.5. Earthing
The transmitters are fitted with internal and external earth terminals.

10. SETTING AND REGULATION
APCE..., APRE... transmitters are factory calibrated to the range stated in the order or to the basic range.
After installation, the transmitter’s zero-point may drift and require adjustment.
This applies particularly in cases where the measurement range is small, where the impulse lines are filled with
a separating liquid or where APCE..., APRE... transmitters are used with remote diaphragm seals.
10.1. Transmitter Range, Definitions
10.1.1. The maximum range of absolute or differential pressure which the transmitter can measure is called
the “basic range” (for specifications of basic ranges see 5.2.1, 5.3.1, 5.4.1 and 5.5.1 and 5.6.1).
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 5.2.1, 5.3.1, 5.4.1, 5.5.1 and 5.6.1.
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.
Parameters of an informational nature which cannot be altered include the following:
f) upper limit of the maximum range;
g) lower limit of the maximum 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, factory 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 in order to compensate for
measurement deviation caused by a change in position when the transmitter is installed.
The transmitter may also be calibrated, by taking readings with the input pressure controlled using a standard
device. This process and zero-point adjustments are called “Calibration”.
10.2.4. Configuration and Calibration of the transmitter are carried out using an Aplisens KAP-03
communicator, certain HART communicators or a PC with HART/RS232 or HART/USB Converter and Aplisens
Raport 2 software.
Together with the “RAPORT 2” configuration software there is “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.
After configuration it is important to protect the transducers using command HART [247].
During work transmitter should be safe prior to entries. This prevents accidental or intentional
changes configurational data. The protection function is accessible in KAP-03 communicator,
“Raport's 2” software, as well as, in applying DD or DMT programs libraries.
