Description
The Automation Components Inc (ACI) 101792 Differential Pressure Switch is a normally closed manual reset unit with a 1.25–12 inch water column range used to monitor pressure differences and control actions in HVAC systems. It detects changes in air or gas pressure and opens the circuit when set thresholds are exceeded requiring manual reset to resume operation. It operates through a pressure-sensing diaphragm that triggers switching based on differential levels. Positioned along ductwork or connected tubing, it interfaces with control circuits to manage safety and operational response.
