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

questions remain regarding a specific application, you can obtain further information:
If the serial number on the product label and/or the 2D code on the hexagon gets illegible (e.g.
by mechanical damage or repainting), the retraceability of the instrument is not possible any
more.

Observe the relevant national regulations (e.g.: IEC 60079-14, NEC, CEC)
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!
Consider the details given in the EC-type examination certificate as well

6. Packaging
Has everything been supplied?
Check the scope of supply:
Completely assembled pressure transmitters; with flush version IS-21 including pre-
assembled sealings and protection cap.
EC-type examination certificate and Control Drawing (FM, CSA) 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.
In order to protect the diaphragm, the pressure connection of the instrument IS-21-S, -F 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.
7. Starting, operation
Required tools: wrench (flats 27 or flats 41), 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.
Pay attention to any liquid leaking out, for this points to a diaphragm

For Model IS-20-S, -F you have to provide for a sealing element; exceptions are
instruments with self-sealing threads (e.g. NPT thread).
For Model IS-21-S, -F the sealing ring is included in delivery.
Please refer to our data sheet “Pressure gauge sealing washers AC 09.08” in WIKA’s
product catalog Pressure and Temperature Measurement 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 flats 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.

Warning
to the housing. The simultaneous connection of housing and cable screen
to ground is only permitted if ground loop problems between the screen
connection (e.g. at the power supply) and housing can be excluded
(see EN 60079-14).
Supply the pressure transmitter from an intrinsically safe current circuit (Ex ia). Consider both the internal capacitance and inductance. Cover flying leads with fine wires by an end splice (cable preparation). The bayonet-connector is made of light metal, a material which is not permissible for
group I applications (mining).
Consider that cables for use in zones 1 and 2 must be checked with a test voltage
between conductor/earth, conductor/screen, screen/earth of more than 500V (AC).
Operate the pressure transmitter with a shielded cable and earth the shield at least
on one side of the cable, if the cable is longer than 30 m or if it is run outside of the
building.
Ingress protection per IEC 60529 (The ingress protection classes specified only apply
while the pressure transmitter is connected with female connectors that provide the
corresponding ingress protection).
Ensure 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.
Please make sure that the ends of cables with flying leads do not allow any ingress of
moisture.

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 10 „Troubleshooting“.

4. Funktion
IS-20: Druckanschluss (eigensicher) mit innenliegender Membran (Standardausführung)
IS-21: Druckanschluss (eigensicher) mit frontbündiger Membrane für hochviskose oder
kristallisierende Medien, die die Bohrung des Druckanschlusses zusetzen können.
IS-2X-S: Druckmessgerät (eigensicher) Ausführung mit Stecker- bzw. Kabelanschluss
IS-2X-F: Druckmessgerät (eigensicher) Ausführung Feldgehäuse
IS-20-H: Druckmessgerät (eigensicher) Ausführung Höchstdruck
Funktion: Mittels Sensorelement und unter Zuführung von Hilfsenergie wird über die Verformung einer Membran der anstehende Druck in Ihrer Anwendung in ein verstärktes standardisiertes elektrisches Signal umgewandelt. Dieses elektrische Signal verändert sich proportional
zum Druck und kann entsprechend ausgewertet werden.
