This series of pressure switches are used to monitor the difference between two pressures. For example, they can be used to monitor filter conditions and signal when the filter is becoming blocked. They can also be used as flow monitoring switches if used across orifice plates etc.
Max. Line Pressure
Pressure range >250mbar …………….34 bar
Pressure range <125 mbar …….….….. 14 bar
10 amp at 250V 50Hz Inductive load
1 amp at 30V dc Inductive load
For other voltages and currents please consult our technical department.
Dimensions of the diaphragm housing are such that the movement of the diaphragm is stopped when the diaphragm exceeds the range.
This ensures that the differential pressure switches will accept the accidental application of 4 times the range without damage except for a possible setting shift of up to 2 % of the range.
It is possible that these switches can be modified to accept the full line pressure on one side of the diaphragm.
