and observe the applicable standards and directives for special applications
(e.g. with dangerous media such as oxygen, acetylene, flammable gases or
liquids and toxic gases or liquids and with refrigeration plants or compressors).
If you do not o serve the appropriate regulations, serious injuries and/or
damage can occur!
nOpen pressure connections only after the system is without pressure!
nPlease make sure that the pressure transmitter is only used within the overload
threshold limit all the time!
nObserve the ambient and working conditions outlined in section 7 Technical data.
nEnsure that the pressure transmitter is only operated in accordance with the provisions
i.e. as described in the following instructions.
nDo not interfere with or change the pressure transmitter in any other way than
described in these operating instructions.
nRemove the pressure transmitter from service and mark it to prevent it from being
used again accidentally, if it becomes damaged or unsafe for operation.

F-20: Standard pressure connection
F-21: Pressure connection with flush diaphragm for highly viscous or solids entrained
media which might clog the pressure port.
Function: With the pressure transmitter you measure the pressure of your application, which
is trans-formed into an electric signal. This electric signal changes in proportion to the
pressure and can be evaluated correspondingly.
Accessories: For details about the accessories, please refer to WIKAs price list, WIKAs

In order to protect the diaphragm, the pressure connection of the instrument F-21 is provided
with a special protection cap.
Required tools: wrench (flats 27), screw driver
nPay attention to any liquid leaking out, for this points to a diaphragm damage.
nCheck the diaphragm visually for any damage.
nUse the pressure transmitter only if the diaphragm is undamaged.
nUse the pressure transmitter only if it is in a faultless condition as far as the
safety-relevant features are concerned.
Diaphragm test for your safety
Warning
!
It is necessary that before starting the pressure transmitter you test the diaphragm, as this is
a safety-relevant component.
7. Starting, operation
Has everything een supplied?
Check the scope of supply:
n Completely assembled pressure transmitters; with flush version F-21
including pre-assembled sealings and protection cap.
Installation
nRemove the protection cap only just before installation and absolutely avoid
any damage to the diaphragm during installation as well.
nEnsure that the cable diameter you select fits 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.
nConnect the instrument to earth via the pressure connection and/or
connection terminal 5.
nHold the instrument on the flat of the nut with an appropriate tool and tighten
the screws to the required torque or unscrew it as the case may be.
Do not hold onto the housing with pliers to screw or unscrew.
n Remove this protection cap only just before installing the pressure
transmitter in order to prevent any damage to the diaphragm.
nEnsure that the pressure connection thread and the connection contacts
will not be damaged.
n Mount the protection cap when removing and transporting the instrument.
6. Packaging
nInspect the pressure transmitter for possible damage during transportation.
Should there be any obvious damage, inform the transport company and WIKA
without delay.
nKeep the packaging, as it offers optimal protection during transportation
(e.g. changing installation location, shipment for repair).
nKeep the protection cap of the pressure connection thread and the diaphragm
for later storage or transport.
For Model F-20
the sealing ring
is available as
an optional
extra.
For Model F-21

Warning
When touching the pressure transmitter, keep in mind that the surfaces of the
instrument components might get hot during operation.
Caution 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 Trouble shooting.
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.

Pressure standard with adequate accuracy
means with an accuracy that is at least 3x
more accurate than the accuracy indicated

nAdjust the span (S) by generating the
higher limit of the pressure range.
nCheck the zero point.
nIf the zero point is incorrect, repeat

Function of the test circuit for 2-wire
By means of the test circuit the current can be metered during normal operation without hav-
ing to disconnect the instrument. For that purpose you have to connect an ammeter (internal
resistance < 15 Ohm) to the test /- terminals.
