2.1 Intended use
The pressure transmitter is used to convert pressure into an electrical signal.
The pressure transmitter has been designed and built solely for the intended use described here
and may only be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the pressure transmitter outside of its technical specications 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.
Before installation, commissioning and operation, ensure that the appropriate
pressure transmitter has been selected in terms of measuring range, design and
specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
Further important safety instructions can be found in the individual chapters of these
operating instructions.

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 countryspecic 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

For special model numbers, e. g. MG-10000, please note the specications stated on the
delivery note.
For further specications, see WIKA data sheet PE 81.44 and the order documentation.
When designing the system, please note that the values given (e.g. burst pressure,
overpressure safety) are dependent upon the material, thread and gasket used.
4. Design and function
4.1 Description
By means of a sensor element and by applying power, the prevailing pressure is converted into an
amplied standardised electrical signal via the deformation of a membrane. This electrical signal
varies in proportion to the pressure and can be evaluated accordingly.
GB
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage
5. Transport, packaging and storage
5.1 Transport
Check the pressure transmitter for any damage that may have been caused during transportation.
GB
Obvious damage must be reported immediately.
A recieved-goods inspection determines the purity of the pressure transmitter. It is only
guaranteed if the packaging is undamaged or unopened.
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: -25 ... +80 °C
■
Humidity: 15 ... 95 % (no condensation)
Only ever store the pressure transmitter in its original packaging.
WARNING!
Before storing the pressure transmitter (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
Required tool: SW 24 open-ended spanner
WARNING!
Prior to commissioning, the pressure transmitter must be subjected to a visual
inspection.
Only use the pressure transmitter if it is in perfect condition with respect to safety.
Making the mechanical connection
■
To ensure that the wetted parts do not get soiled, the protection
cap should not be removed until immediately prior to mounting.
■
Use only BAM-certied gaskets.
■
During mounting, make sure that the sealing faces at the pressure
transmitter and the measuring point are clean and undamaged.
■
Only ever screw in, or unscrew, the pressure transmitter to the
max.
20 Nm
prescribed torque via the spanner-ats, and using tools which are
appropriate and clean for use with oxygen.
The correct torque depends on the dimensions of the process
connection and the gasket used (form/material). When screwing
in or unscrewing the pressure transmitter, do not use the housing or plug for purchase.
■
When screwing in, do not cross the threads.
■
Only lubricate thread with materials approved for use with oxygen.
■
For information on tapped holes and welding sockets, please refer to our Technical Information

Making the electrical connection
■
Ground the pressure transmitter via the process connection.
■
This is Protection Class 3 equipment for connection at low voltages, which are separated from
the power supply or voltage by greater than AC 50 V or DC 120 V. Preferably, a connection
to an SELV or PELV circuit is recommended; alternatively protective measures from
HD 60346-4-41 (DIN VDE 0100-410).
■
Option for North America: The connection can be made in line with "Class 2 Circuits"
or "Class 2 Power Units" in accordance with CEC (Canadian Electrical Code) or
NEC (National Electrical Code).
■
Select a cable diameter that matches the cable gland of the plug. Make sure that the cable
gland of the mounted plug has a tight t. To guarantee the ingress protection, tighten the gland.
■
For cable outlets, make sure that no moisture enters at the cable end.

7.1 Maintenance
This pressure transmitter is maintenance-free.
GB
Repairs must only be carried out by the manufacturer.
When performing maintenance work, the purity requirements of the applicable standards must be
observed.
7.2 Cleaning
CAUTION!
■
Before cleaning, correctly disconnect the pressure transmitter from the
