United Electric J120-532 Pressure Switch 0 To 50 WC Vac Explosion Proof 50 Psi

Description:

The United Electric Controls J120-532 Pressure Switch is used in industrial low-pressure monitoring and control systems to provide automatic electrical switching when preset pressure levels are reached. Commonly installed in HVAC systems, combustion air equipment, filtration systems, process ventilation systems, dust collection equipment, and industrial automation applications requiring reliable low-pressure monitoring and explosion-proof protection. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of existing pressure sensing and control systems.

Applications:

The United Electric Controls J120-532 Pressure Switch is commonly used in airflow proving systems, filter monitoring applications, burner management systems, ventilation controls, process pressure monitoring, and industrial safety shutdown systems. The switch utilizes a low-pressure diaphragm sensing element to detect pressure changes and actuate electrical contacts for alarms, interlocks, shutdown functions, and automatic process control, helping maintain safe and efficient operation of critical industrial equipment in hazardous industrial environments.
