P12 Series Differential Pressure Controls
Suitable for use with oil and/or non-corrosive refrigerants
A difference in pressure between the two sensing elements actuates the switch.
- Factory-set to open the switch from COM to 1 at a differential pressure of 18 psi (124 kPa) and close the switch from COM to 1 at a differential pressure of 12 psi (83 kPa)
- Not field-adjustable
- To completely monitor the lubrication on two refrigeration compressors that one motor drives, connect this control to a P28 Lube Oil Control with time delay.
