2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate pressure
sensor 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.
■
Prior to opening the instrument, disconnect it from the mains.
■
Always operate the pressure sensor within the overpressure limit.
■
Observe the working conditions in accordance with chapter 3 "Specications".
■
For the application of the pressure sensor in connection with aggressive/corrosive media
and for avoiding mechanical damages, see chapter 3 „Specications“.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The pressure sensor is used to convert pressure into an electrical signal.
The pressure sensor has been designed and built solely for the intended use described here and may
only be used accordingly.
This is class B equipment for emissions and is intended for use in industrial environments. In other
environments, e.g. residential or commercial installations, it can intefere with other equipment under
certain conditions. In such circumstances the operator is expected to take the appropriate measures.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the pressure sensor 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 should qualication be 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 sensors can result in a risk to persons, the
environment and equipment.
Take sucient precautionary measures.
WARNING!
When touching the pressure sensor, please note that the surfaces of the instrument
components can become hot during operation.

tion and sealing, restrictions in overload safety can result.
A higher overload safety will result in a higher temperature error.

4. Design and function
4.1 Description
By means of a sensor element and by applying power, the prevailing pressure is converted into 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.
4.2 Scope of delivery
Cross-check scope of delivery with the delivery note.
Flush design (P-31) with pre-mounted sealings and protection cap.
For model P-31, the sealing ring is included in the delivery.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.
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).
Keep the protection cap of the process connection for later transport or storage.

5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +85 °C [-40 ... +185 °F]
■
Humidity: 45 ... 75 % relative humidity (no condensation)
WARNING!
Before storing the pressure sensor (following operation), remove any residual media.This
is of particular importance if the medium is hazardous to health, e.g. caustic, toxic, carcino-
genic, radioactive, etc.
6. Commissioning, operation
CAUTION!
Prior to commissioning, the pressure sensor must be subjected to a visual inspection.
■
Check the diaphragm for any visible damage, since this is a safety-relevant component.
■
Leaking uid is indicative of damage.
■
Only use the pressure sensor if it is in perfect condition with respect to safety.
6.1 Making the mechanical connection
Required tool: Open-ended spanner (spanner width 27 or 41)
■
With ush process connections, remove the protection cap not until shortly
before mounting. During installation, ensure that the diaphragm is not damaged .
■
During mounting, make sure that the sealing faces at the pressure sensor
and the measuring point are clean and undamaged.
■
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 process connection
and the sealing used (form/material).
■
When screwing in, avoid any jamming of the threads.

6. Commissioning, operation
Types of sealing
Correct sealing of the process connections with parallel threads 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 sealings see WIKA data sheet AC 09.08 or under www.wika.com.
Models P-30 and P-31 are high-quality precision measuring instruments. Installation-related
inuences (e.g. position dependence, tightening torque) must be eliminated by correcting
the zero point in the application or via the software "EasyCom".Thus an optimum measuring
accuracy of the overall system is ensured.

angle housing (5).
6. Connect the cable ends to the appropriate connection terminals on the terminal block (6) (see table
"Connection diagrams").
7. Press the angle housing (5) onto the terminal block (6).
8. Tighten the cable gland (2) around the cable. Make sure that the sealings are not damaged and that
the cable gland and sealings are assembled correctly in order to ensure ingress protection.
