Intended Applications
-
The dual pressure switch is a device to monitor system pressure
and has up to two switching outputs and one analog output.
-
The instruments must only be installed in systems where the
maximum pressure Pmax or the maximum temperature Tmax is
not exceeded (according to the values on the type label).
-
Attention: This device is not designed to be used as the only
safety relevant element in pressurized systems according PED
97/23/EC.
Only assemble or disassemble the device when depressurized!
