UNITED ELECTRIC CONTROLS J120-134 PRESSURE SWITCH J120134

Description:

The United Electric Controls J120-134 Pressure Switch is used in industrial process control systems to monitor low-pressure conditions and provide automatic electrical switching when preset pressure limits are reached. Commonly installed in oil and gas facilities, chemical processing plants, compressors, pumps, and industrial automation systems requiring reliable 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 J120-134 Pressure Switch is commonly used in pump protection systems, compressor control circuits, pneumatic systems, process pressure monitoring, emergency shutdown systems, and industrial alarm applications. The switch utilizes a pressure-actuated diaphragm sensing mechanism 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 environments.
