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 specications contained in these operating instructions must be observed.
Improper handling or operation of the pressure transmitter outside of its technical specications requires
the instrument to be taken out of service immediately and inspected by an authorised WIKA service
engineer.
Before installation, commissioning and operation, ensure that the appropriate pressure
transmitter has been selected in terms of measuring range, design and specic measuring
conditions.
Non-observance can result in serious injury and/or damage to equipment.
WARNING!
■
Open the connections only after the system has been depressurised.
■
Observe the working conditions in accordance with chapter 3 "Specications".
■
Always operate the pressure transmitter within the overpressure limit.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

4. Design and function / 5. Transport, packaging ...
4. Design and function
4.1 Description
The prevailing pressure is measured at the sensor element through the deformation of a diaphragm.
By supplying power, this deformation of the diaphragm is converted into an electrical signal. The output
signal from the pressure transmitter is amplied and standardised.
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: See chapter 3.6 "Operating conditions"
GB
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..

CAUTION!
GB
6.1 Mechanical mounting
■
The sealing faces at the instrument have to be undamaged and
clean.
■
When screwing the instrument in, the force required to do this must
not be applied through the casing, but only through the spanner ats
provided for this purpose and using a suitable tool.
The correct torque depends on the dimensions of the process
connection and the gasket used (form/material).
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
Only use the pressure transmitter if it is in perfect condition with respect to safety.
Do not exceed the following tightening torque:
max. 30 Nm
■
When screwing in, do not cross the threads.

For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.
6.2 Electrical mounting
■
The instrument must be grounded 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.
14026285.01 11/2012 GB/D/F/E
For sealing process connections with tapered
threads, the sealing must be made in the threads
using additional sealing material, e.g. PTFE tape
(EN 837-2).

■
Select a cable diameter that matches the cable gland of the mating connector.
Connect the pins of the mating connector in accordance with the connection diagram.
Ensure that all seals are correctly tted and have not been damaged.

6. Commissioning, operation
Humidity can aect the operating characteristics of
electronic components and sensors,
positioning prevents problems and extends the
service life. Electronic components and sensors can
be adversely aected due to temperature changes in
combination with condensing humidity (e.g. in evaporators with de-icing systems).
Although the ingress protection of the pressure
transmitter is IP 67 or IP 6K9K, this is not hermetically
sealed. Under critical conditions, there is the danger
that small air volumes can penetrate or diuse
through the case. Thus, over time, humidity can
collect in the sensor and cause measuring errors.
It is therefore recommended that the pressure transmitter is placed in a location with low humidity and
temperature uctuations. For chill cabinets or cold
rooms, this place is on the inlet pipe on the outside of
the main cooling chamber, e.g. below the chill cabinet
where the piping comes out of the chill cabinet.
If positioning is required closer to the evaporator, it is
recommended that a capillary
