Air differential pressure switch for air conditioner

What is a Differential Pressure Switch? Differential pressure switches are part of our product portfolio, but what is a differential pressure switch? A differential pressure switch is an electro-mechanical device which is used for sensing a difference in pressure between two points. How does a Differential Pressure Switch work? When connected to two pressure sources, the differential pressure switch can be used as an alarm to make or break a circuit as the pressure rises or falls beyond the preset value. The internal diaphragm within the differential pressure switch deflects under pressure to make the contact; this could be either a SPST or SPDT contact. The set point can be factory preset or field adjustable. Differential pressure switches tend to be used for energy saving or preventative maintenance, for example; monitoring air filters for blockages. As the filter clogs or blocks up, the pressure on the high side will rise and once at the activation point, the pressure switch will change state.
