Compland Oil Pressure Differential Switch OPS2

The OPS2 monitors the oil pressure differential protecting the compressor against damage if the oil differential becomes too low. Internal channels drilled through the housing link the switch to the inlet and outlet ports of the oil pump.

The brass mechanical sensor component is fitted as standard on all DWM Semi-Hermetic compressors which have a high pressure oil pump. It is directly screwed into the pump housing. The black electronic switch is screwed onto the brass mechanical sensor. If the electronic switch has to be removed from the brass sensor the refrigeration circuit will not be open to the atmosphere.

The mechanical sensor fitting for the OPS2 is the same as for the OPS1. The electronic switches are interchangeable but require changes to the wiring circuit.
