United Electric H300K 0-80 Pressure Controller WCD 15 Amp 250 Vac 225 Psi

Description:

The United Electric Controls H300K Pressure Controller is used in low-pressure and differential pressure monitoring systems to provide automatic electrical switching when preset pressure levels are reached. Commonly installed in HVAC equipment, air handling systems, filtration units, combustion air systems, and industrial process equipment requiring precise low-pressure control and equipment 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 H300K Pressure Controller is commonly used in cleanroom monitoring, airflow proving systems, dust collection equipment, filter monitoring, ventilation systems, burner management systems, and industrial process control installations. The controller 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 low-pressure systems.
