2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate pressure
switch has been selected in terms of measuring range, design and specic measuring
conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
■
Open the connections only after the system has been depressurised.
■
Observe the working conditions in accordance with Chapter 3 "Specications".
■
Always operate the pressure switch within the overpressure safety range.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The pressure switch is used to convert pressure into an electrical signal indoors and outdoors.
The instrument has been designed and built solely for the intended use described here, and may only
be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the instrument outside of its technical specications requires the instrument to
be taken out of service immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

2.2 Personnel qualication
WARNING!
Risk of injury if qualication is insucient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
personnel who have the qualications described below.
Skilled personnel
Skilled personnel 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.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.
WARNING!
Residual media in dismounted pressure switches can result in a risk to persons, the
environment and equipment.

11430486.07 04/2015 EN/DE/FR/ES
4. Design and function
4.1 Description
By means of a sensor element and by supplying power, the prevailing pressure is converted into a
switching signal or an amplied standardised electrical signal via the deformation of a diaphragm. This
electrical signal varies in proportion to the pressure and can be evaluated accordingly.
PSD-30: Process connection with internal diaphragm (standard version).
PSD-31: Process connection with ush diaphragm for highly viscous or crystallising media that may clog
the bore of the process connection.
4.2 Scope of delivery
Cross-check the scope of delivery with the delivery note.
For ush design (model PSD-31) with pre-mounted sealings and protection cap.
5. Transport, packaging and storage
For the protection of the diaphragm, the ush design (model PSD-31) is delivered with a
special protection cap.
■
In order to avoid damage at the diaphragm and/or the process connection thread,
remove the protection cap by hand only just before installation.
■
Keep the protection cap for subsequent storage or transport.
■
Fit the protection cap before dismounting and transporting the instrument.
5.1 Transport
Check the instrument for any damage that may have been caused by transport. With ush design
(model PSD-31), additionally check the diaphragm for any optical damage.
Obvious damage must be reported immediately.

19WIKA operating instructions pressure switch, model PSD-3x
EN
11430486.07 04/2015 EN/DE/FR/ES
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: -20 ... +80 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
In order to protect the diaphragm, mount the protection cap before storing the instrument.
WARNING!
Before storing the instrument (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..
6. Commissioning, operation
CAUTION!
Only use the pressure switch if it is in perfect condition with respect to safety.
Check the following points before commissioning:
■
Check the diaphragm for any visible damage, since this is a safety-relevant component.
■
Leaking uid is indicative of damage.
Required tool: SW 27 open-ended spanner, screwdriver

6. Commissioning, operation
Correct sealing of the process connections with parallel threads at the sealing face must be made
using suitable at gaskets, sealing rings or WIKA prole sealings.
The sealing of tapered threads (e.g. NPT threads) is made by providing the thread with additional
sealing material such as, for example, PTFE tape (EN 837-2).
For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.
Seal
6.1 Making the mechanical connection
■
With ush process connections (model PSD-31), remove the protection
cap not until shortly before mounting. During installation, ensure that the
diaphragm is not damaged.
■
The sealing faces at the instrument always have to be clean.
■
Only ever screw in, or unscrew, the instrument via the spanner ats.
Never use the case as a working surface.
■
The correct torque depends on the dimensions of the pressure connec-
tion and the gasket used (form/material).
■
When screwing in, do not cross the threads.
■

Information IN 00.14 at www.wika.de.
