Purpose of pressure switch
WebThe switch will not change back until the pressure has fallen to the range value less the differential value. E.g. If the range setting is 2.5bar and the differential setting is 0.5bar, the switch will change over when the pressure has risen to 2.5bar and will not change back until the pressure has fallen below 2.0bar. > Open the catalog to page 1 WebJan 25, 2024 · A furnace pressure switch is an automatic safety feature located near the motor.

WebFor most mechanical pressure switches, the deadband value is specified in a percentage range, typically 10 – 30%. This percentage range implies that the difference between the setpoint and the reset point can be at a value between 10 – 30% less than the setpoint. In other words, if a setpoint is 10, then the reset point can be between 7 and 9. WebWhat is a Pressure Switch?1. Pressure Switch operating principle (common pressure switch application)2.
