Product Description
Product Description of the HVAC differential fan pressure switch

When the system pressure is higher or lower than the safety pressure rated, occurrence of disc instantaneous mobile sensors, through the connecting rod to drive switch connector on or off, when the pressure drops to or rated recoveryvalue, disc instant reset switch, automatic reset, or simply to say is when the measured pressure exceeds the rated value, the displacement of the free end of the elastic element, directly or after comparing push switch element, change theswitching element to control the on-off state, the measured pressure to.
