Intended Applications
The pressure switches are specifically applied for monitoring and controlling of operations using
maximum and minimum pressures. A micro switch triggers an electrical signal when minimum or
maximum pressure are reached.
DANGER
The switch may only be used in the specified fields of application (see type label).
The temperature has to be within the specified ranges, the pressure values and the electrical
rating must not exceed the values specified.
Observe also the applicable national safety instructions for assembly, commissioning and
operation of the switch.
The switch is not designed to be used as the only safety relevant element in pressurized systems
according to DGR 97/23/EC.
Without special provisions/actions, pressure switches must not be used for pure gas or hydrogen
applications.
