P74

Differential Pressure

The P74 series 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 the mechanical switching differential.

Features

  • Heavy duty pressure elements.
  • These controls may be used in combination with series P28 lube oil protection control on two compressor, single motor units.
