2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate pressure
transmitter has been selected in terms of measuring range, design and specic measuring
conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
■
Open the connections only after the system has been depressurised.
■
Observe the working conditions in accordance with Chapter 3 "Specications".
■
Always operate the pressure transmitter within the overpressure limit.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The pressure transmitter is used to convert pressure into an electrical signal.
The instrument has been designed and built solely for the intended use described here, and may only
be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the pressure transmitter outside of its technical specications requires the
instrument to be taken out of service immediately and inspected by an authorised WIKA service
engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

2.2 Personnel qualication
WARNING!
Risk of injury if qualication is insucient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
personnel who have the qualications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training, knowledge
of measurement and control technology and on their experience and knowledge of country-specic
regulations, current standards and directives, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.

4. Design and function / 5. Transport, packaging and storage
4. Design and function
4.1 Description
By means of a sensor element and by applying power, the prevailing pressure is converted into an
amplied standardised electrical signal via the deformation of a diaphragm. This electrical signal varies
in proportion to the pressure and can be evaluated accordingly.
4.2 Scope of delivery
Cross-check the scope of delivery with the delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the pressure transmitter for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation
site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +80 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
WARNING!
Before storing the pressure transmitter (following operation), remove any residual media.
This is of particular importance if the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.

6. Commissioning, operation
6. Commissioning, operation
Required tool: Open-ended spanner (spanner width 27), screwdriver
CAUTION!
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
■
Leaking uid is indicative of damage.
■
Only use the pressure transmitter if it is in perfect condition with respect to safety.
Making the mechanical connection
■
For model A-10 with parallel thread, the sealing ring is included in the delivery.
■
During mounting, make sure that the sealing faces at the pressure transmitter
and the measuring point are clean and undamaged.
■
Only ever screw in, or unscrew, the instrument via the spanner-ats and to
the prescribed torque using an appropriate tool. The correct torque depends
on the dimensions of the pressure connection and the gasket used (form/
material). When screwing in or unscrewing the pressure transmitter, do not
use the housing for purchase.
■
When screwing in, do not cross the threads.

Types of sealing
Correct sealing of the process connections with parallel threads at the sealing face  must be made
using suitable at gaskets, sealing rings or WIKA prole sealings.
The sealing of tapered threads (e.g. NPT threads) is made by providing the thread with additional
sealing material such as, for example, PTFE tape (EN 837-2).
For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.
Making the electrical connection
■
The instrument must be earthed via the process connection!
■
The power supply for the pressure transmitter must be made via an energy-limited electrical circuit
in accordance with section 9.3 of UL/EN/IEC 61010-1, or an LPS to UL/EN/IEC 60950-1, or class 2
in accordance with UL1310/UL1585 (NEC or CEC). The power supply must be suitable for operation
above 2,000 m should the pressure transmitter be used at this altitude.
■
Select a cable diameter that matches the cable gland of the plug. Make sure that the cable gland of
the mounted plug has a tight t and that the seals are present and undamaged. Tighten the threaded
connection and check that the seal is correctly seated, in order to ensure a tight seal.
■
For cable outlets, make sure that no moisture enters at the cable end.

Fitting a DIN 175301-803 angular connector
1. Loosen the screw (1).
2. Loosen the cable gland (2).
3. Pull the angle housing (5), with the terminal block (6)
inside, away from the instrument.
4. Via the mounting hole (D), lever the terminal block (6)
out of the angle housing (5). Do not try to push the
terminal block (6) out using the screw hole (1) or the
cable gland (2), otherwise the sealing of the angle
housing could be damaged.
5. Select a conductor with an outer diameter matched to the angle housing's cable gland. Slide the
cable through the cable gland (2), washer (3), gland seal (4) and angle housing (5).
6. Connect the cable ends to the appropriate connection terminals on the terminal block (6) (see table
"Electrical connections").
7. Press the angle housing (5) onto the terminal block (6).
8. Tighten the cable gland (2) around the cable. Make sure that the seals are not damaged and that
the cable gland and seals are assembled correctly in order to ensure ingress protection.
9. Place the at, square gasket over the pressure transmitter's connection pins.
10. Slide the terminal block (6) onto the pressure transmitter's connection pins.
11. Secure the angle housing (5) and terminal block (6) to the pressure transmitter with the screw (1).
