GB
1. Important details for your information
Read these operating instructions before installing and starting the pressure transmitter.
Keep the operating instructions in a place that is accessible to all users at any time.
The following installation and operating instructions have been compiled by us with great care
but it is not feasible to take all possible applications into consideration. These installation and
operation instructions should meet the needs of most pressure measurement applications. If
questions remain regarding a specific application, you can obtain further information:
Via our Internet address www.wika.de / www.wika.com
The product data sheet is designated as PE 81.47
Contact WIKA for additional technical support (+49) 9372 / 132-295
With special model number, e.g. C-20000, please note specifications in the delivery note.
If the serial number on the product label gets illegible (e.g. by mechanical damage or repainting), the retraceability of the instrument is not possible any more.
WIKA pressure transmitters are carefully designed and manufactured using state-of-the-art
technology. Every component undergoes strict quality and environmental inspection before
assembly and each instrument is fully tested prior to shipment. Our environmental management system is certified to DIN EN ISO 14001.
Use of the product in accordance with the intended use C-2:
Use the pressure transmitter to transform the pressure into an electrical signal.
Knowledge required
Install and start the pressure transmitter only if you are familiar with the relevant regulations
and directives of your country and if you have the qualification required. You have to be
acquainted with the rules and regulations on measurement and control technology and electric circuits, since this pressure transmitter is „electrical equipment“ as defined by EN 50178.
Depending on the operating conditions of your application you have to have the corresponding knowledge, e.g. of aggressive media.
2. A quick overview for you
If you want to get a quick overview, read Chapters 3, 5, 7 and 10. There you will get some
short safety instructions and important information on your product and its starting. Read
these chapters in any case.

4. Function
The pressure prevailing within the application is transformed into a standardised electrical
signal through the deflection of the diaphragm, which acts on the sensor element with the
power supply fed to the transmitter. This electric signal changes in proportion to the pressure
and can be evaluated correspondingly.

performance and specific measurement conditions prior to installing and
starting the instrument.
Observe the relevant national regulations (e.g.: EN 50178) and observe the
applicable standards and directives for special applications (e.g. with
dangerous media such as acetylene, flammable gases or liquids and toxic
gases or liquids and with refrigeration plants or compressors). If you do not
observe the appropriate regulations, serious injuries and/or damage
can occur!
5. For your safety / 6. Packaging
Open pressure connections only after the system is without pressure!
!
Warning
Ensure that the pressure transmitter is only operated in accordance with the provisions i.e.
as described in the following instructions.
Do not interfere with or change the pressure transmitter in any other way than described in
these operating instructions.
Remove the pressure transmitter from service and mark it to prevent it from being used
again accidentally, if it becomes damaged or unsafe for operation
Take precautions with regard to remaining media in removed pressure transmitter.
Remaining media in the pressure port may be hazardous or toxic!
Have repairs performed by the manufacturer only.
Please make sure that the pressure transmitter is only used within the over-
load threshold limit all the time!
Observe the ambient and working conditions outlined in section 7 „Technical
data”.
6. Packaging
Has everything been supplied?
Check the scope of supply:
Completely assembled pressure transmitters
Inspect the pressure transmitter for possible damage during transportation. Should
there be any obvious damage, inform the transport company and WIKA without delay.
Keep the packaging, as it offers optimal protection during transportation (e.g. chan-
ging installation location, shipment for repair).
Ensure that the pressure connection thread and the connection contacts will not be
damaged.

8. Maintenance, accessories
WIKA pressure transmitters require no maintenance.
Have repairs performed by the manufacturer only.
Accessories
For details about the accessories (e. g. connectors), please refer to WIKA‘s price list, WIKA‘s
product catalog on CD or or contact our sales department.
9. Trouble shooting
Open pressure connections only after the system is without pressure!
When designing your plant, take into account that the stated values (e.g. burst pressure,
over pressure safety) apply depending on the material, thread and sealing element used.
Functional test
The output signal must be proportional to the pressure. If not, this might point to a
damage of the diaphragm. In that case refer to chapter 9 „Troubleshooting“.
Open pressure connections only after the system is without pressure!
