Description
The A.J. Antunes 8024401045 Pressure Switch is a differential pressure-sensing system with an operating range of 0.17 to 1 inch of water column, used to detect draft conditions within a pressurized pathway and switch an electrical contact when the sensed pressure falls within or outside the set threshold. providing a compact footprint that fits into tight cabinet spaces where pressure monitoring is required along the gas side of the circuit. Within HVAC systems, it is placed on forced air sections of furnaces and boilers, venting the pathway before the control board permits the ignition sequence to advance.
