H50PS Series Pressure Controller
Overview
The H50PS series pressure controller is a micro switch. It closes or opens the control circuit according to the pressure rise and fall of the controlled medium. Widely used in power shift transmissions, anti-skid braking systems, excavator hydraulic systems, air compressors, and other industrial equipment that require pressure protection.
Working principle
The H50PS series pressure controller is a device that senses system pressure through a diaphragm and transmits the pressure to a spring, pushing the switch contacts to open or close the circuit when the pressure reaches the set point. The H50PS series pressure controller is professionally designed to withstand persistent loads, with action values set by the factory and adjustable on site.
