2. Function
F-20: Pressure connection with internal diaphragm (standard version).
F-21: Pressure connection with ush diaphragm for highly viscous or solids entrained media which might clog the
pressure port.
The pressure prevailing within the application is transformed into a standardised electrical signal through the deection
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.

→ For performance limits, see chapter 6 “Specications”.
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
3.3 Personnelqualication
Skilled personnel
Skilled personnel, authorised by the operator, 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.
WARNING!
■
Select the appropriate pressure transmitter with regard to scale range, performance and specic
measurement conditions prior to installing and starting the instrument.
■
Observe the relevant national regulations and observe the applicable standards and directives for
special applications (e.g. with dangerous media such as acetylene, ammable 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!
■
Open pressure connections only after the system is without pressure!
■
Please make sure that the pressure transmitter is only used within the overload threshold limit all the time!
■
Observe the ambient and working conditions outlined in chapter 6 “Specications”.
■
Observe the technical data for the use of the pressure transmitter in connection with aggressive /
corrosive media and for the avoidance of mechanical hazards.
■
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.
■
Open circuit before removing connector / cover.

4. Packaging
Has everything been supplied?
Check the scope of supply:
■
Completely assembled pressure transmitters.
■
With ush version (F-21) including pre-assembled sealings and protection cap.
■
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 oers optimal protection during transportation (e.g. changing installation location,
shipment for repair).
■
Ensure that the pressure connection thread and the connection contacts will not be damaged.
In order to protect the diaphragm, the pressure connection of the instrument F-21 is provided with a special protection cap.
■
Remove this protection cap only just before installing the pressure transmitter in order to prevent any damage to the
diaphragm or the thread.
■
Keep the protection cap of the pressure connection thread and the diaphragm for later storage or transport.
■
Mount the protection cap when removing and transporting the instrument.
5. Starting, operation
Required tools: wrench (ats 27), screw driver
Diaphragm test for your safety
It is necessary that before starting the pressure transmitter you test the diaphragm visually, as this is a safety-relevant
component.
WARNING!
■
Pay attention to any liquid leaking out, for this points to a diaphragm damage.
■
Check the diaphragm visually for any damage (F-21).
■
Use the pressure transmitter only if the diaphragm is undamaged.
■
Use the pressure transmitter only if it is in a faultless condition as far as the safety-relevant features
are concerned.

■
Remove the protection cap only just before installation and absolutely avoid any damage to the
diaphragm during installation as well (F-21).
■
For Model F-20 you have to provide for a sealing element; exceptions are instruments with
self-sealing threads (e.g. NPT thread). For Model F-21 the sealing is included in delivery.
■
Please refer to our data sheet “Pressure gauge sealing washers AC 09.08” or our website www.wika.de
for details about sealing washers.
■
When mounting the instrument, ensure that the sealing faces of the instrument and the measuring
point are clean and undamaged.
■
Screw in or unscrew the instrument only via the ats using a suitable tool and the prescribed torque.
The appropriate torque depends on the dimension of the pressure connection and on the sealing
element used (form/material). Do not use the case as working surface for screwing in or unscrewing
the instrument.
■
When screwing the transmitter in, ensure that the threads are not jammed.
■
For tapped holes and welding sockets please see Technical Information IN 00.14 for download at
www.wika.de
Electrical connection
■
Connect the instrument to earth via the pressure connection and/or connection terminal 5.
■
For instruments with voltage output or 3 wire current output, use shielded cables, and, if the cables
are longer than 30 m or leave the building, earth the shield at least at one end of the cable.
■
Ensure that the cable diameter you select ts to the cable gland of the connector. Ensure that the
cable gland of the mounted connector is positioned correctly and that the sealings are available and
undamaged.Tighten the threaded connection and check the correct position of the sealings in order
to ensure the ingress protection.
■
Please make sure that the ends of cables with ying leads do not allow any ingress of moisture.

2) Including non-linearity, hysteresis, zero point and full scale error (corresponds to error of measurement per IEC 61298-2). Calibrated in vertical mounting position
with process connection facing downwards.
3) The existence of strong electromagnetic elds in a frequency range of < 2.7 GHz can result in increased measured errors up to 1 % of span. Do not install the
instruments in the vicinity of strong electromagnetic sources of interference (e.g. transmitting device, radio equipment), or use sheath current lters where applicable.
When designing your plant, take into account that the stated values (e.g. 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”.
WARNING!
■
Open pressure connections only after the system is without pressure!
■
Observe the ambient and working conditions outlined in chapter 6 “Specications”.
■
Please make sure that the pressure transmitter is only used within the overload threshold limit at all times!
WARNING!
■
When touching the pressure transmitter, keep in mind that the surfaces of the instrument components
might get hot during operation.
7. Adjustment of zero point / span
We do not recommend to adjust the span potentiometer. It is used for adjustment ex factory and should not
be adjusted by you unless you have adequate calibration equipment at your disposal (at least three times
more accurate than the instrument being tested).
■
Make sure wires are not cut or pinche during disassembly and reassembly of the connector. Open the pressure
transmitter by twisting o the eld case cover.
■
Adjust the zero point (Z) by generating the lower limit of the pressure range.
■
Adjust the span (S) by generating the higher limit of the pressure range.
■
Check the zero point.
■
If the zero point is incorrect, repeat procedure as required.
■
Reassemble the instrument carefully.
■
Make sure all sealings and o-rings are not damaged and correctly installed to assure the rated moisture ingress protection.
