2.1 General sources of hazards
Pressure gauges are pressurized parts where failure can result
in hazardous situations. The selection of pressure gauge should
be made in accordance with the rules set out in EN 837-2
.
2.2 Use in accordance with intended purpose
The devices are only to be used for the intended purpose as
described by the manufacturer.
The devices are used for direct display of differential pressure.
The integrated switching elements are inductive proximity
switches with a groove design, supplied by isolating switch
amplifiers with certified intrinsically safe power circuits. If the
set limit values are exceeded, the output circuits are opened
or closed.
For each use scenario, the corresponding set-up regulations
must be respected. The use in explosion risk area is not
permitted.
2.3 Operator’s responsibility
Safety instructions for proper operation of the device must be
respected. They are to be provided by the operator for use by
the respective personnel for installation, servicing, inspection
and operation. Risks from electrical energy and from the
released energy of the medium, from escaping media and from
improper connection of the device must be eliminated. The
details for this are to be found in the corresponding applicable
set of regulations, such as DIN EN, UVV (accident prevention
regulations) and in sector-specific instances of use (DVWG,
Ex-. GL, etc.) the VDE guidelines and the regulations supplied
by local utilities companies.
The device must be taken out of service and secured against
inadvertently being restarted, if the presumption is that risk-free
operation is no longer possible.

must be adapted to the medium used in the plant. The limit
values indicated in the technical data must not be exceeded.
The safety information detailed in this Operating Manual, exist-
ing national regulations for accident prevention, and the oper-
ator’s internal regulations regarding working, operations and
safety must be respected.
The operator is responsible for all specified servicing,
inspection and installation works being carried out by
authorized and qualified specialists.
2.4 Staff qualifications

Staff specialists are people who are able to assess the work
assigned to them on the basis of their specialized training, their
knowledge and experience and their knowledge of the relevant
standards, and can identify possible risks.
