Mechanical pressure switches

Additonal functions/Connecting schemes

Pressure switches and pressure monitors

Additional functions for Ex-i-equipment

· Housing (500) with terminal connection (IP 65), "blue" cable entry and terminals.

· A lso available with resistor combination for line break and short-circuit monitoring (with isolating amplifier).

! Important:

All pressure switches with the ZF5… additional functions listed here can only be operated in combination with

a suitable isolating amplifier.

DWAM6-576

i Additional information:

Our pressure switches and thermostats are considered to be "simple electrical equipment" within the meaning

of standard EN60079-11: 2007. Testing is not mandatory for this type of equipment.
