Electromechanical Pressure Controls
P12 Series: Differential Pressure Control (Fixed Differential)
Description
The P12 Series Differential Pressure Controls are suitable for use with oil and/or non-corrosive refrigerants. The switch is actuated by a difference in pressure between the two sensing elements. The control is factory-set to open the switch (COM to 1) at a differential pressure of 18 psi (1.2 bar) and close the switch (COM to 1) at a differential pressure of 12 psi (0.83 bar). The control is not field-adjustable.
This control may be connected to a P28 lube oil control, with time delay, to give complete monitoring of lubrication on two refrigeration compressors driven by one motor
