A change in differential pressure will reposition the switching mechanism to cause corrective action of the supplementary control equipment. Poil pressure cutout controls on two compressor, single motor units to reduce the oil system cost. Special low pressure models are available for variable speed and screw compressor oil pressure applications.

The Pseries of differential pressure switches incorporate two opposing pressure elements and an adjustable range setpoint spring with a calibrated scale. The control switches at the indicated setpoint on an increase in differential pressure and switches back to the normal position when the different pressure decreases to the setpoint less.

It operates an SPDT switch at the differential pressure set point. Series pmeasures the pressure difference between two sources: supply lines and return lines.
