Differential Pressure Switch
The model AFS-22 Differential Pressure Switch is a general purpose proving switch designed for HVAC and energy management applications.
The Differential Pressure Switch may be used to sense positive, negative or differential air pressure.
The plated housing on the Differential Pressure Switch contains a diaphragm, a calibration spring and a snap acting switch. The sample connections on each side of the diaphragm accept 0.25" O.D. metallic tubing via the integral compression ferrule and nut.
An enclosure cover guards against accidental contact with the live switch terminal screws and the set point adjusting screw.
The enclosure cover on the Differential Pressure Switch will accept a 0.5" conduit connection.
