2 Safety
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 & DIN 16003 .
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 magnetic spring contacts or inductive proximity switches with a groove design,
supplied by isolating switch amplifiers. 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 areas 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 (see Chapter 10: Faults).
Conversion works or other technical alterations to the device by the customer will violate the approval for
hazardous area and are not permitted. This also applies to installation of spare parts. Possible conversations
or alterations may only be carried out by the manufacturer.
The operational safety of the device is only guaranteed where it is used for its intended purpose. The specification of
the device 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, existing national regulations for accident prevention, and the
operator’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.
The operator is responsible that the device is used in the correct ATEX zone.
2.4 Staff qualifications (target group assessment)
The device may only be installed and started up by specialist staff who are qualified for installation, start-up and
operation of the product.
Specialist staff is people who are able to assess the work assigned to them on the basis of their specialist training,
their knowledge and experience and their knowledge of the relevant standards, and can identify possible risks.
For devices in explosion-protected configuration, these staff must have been trained or instructed in, or be authorized
for, working on explosion-protected devices in potentially explosive plants.
2.5 Signs/Safety markings
The pressure gauge and its surrounding packaging carry markings. These markings show the article number,
measurement range, maximum static pressure, maximum overload and manufacturer. The pressure gauge can be
provided with additional signs and safety markings advising on special conditions:

Advice on the filling liquid

Advice on calibration

Ex (for ATEX configuration)

Oil-can deleted (if oxygen is used)
