Product Description

Product Description
Application

The pressure controller is used for control pressure transmission power switch on/off based on the principle of instability jumping when the dish mental diaphragm is under uniform pressure load.
It is mainly used for protection and control of high and low pressure on household, commercial and automotive air conditioner refrigerating systems, and can also be used to protect and control high and low pressure on air compressor, hydraulic machines, water pump and heat pump, etc. 

 

Operation/Working Principles

when the medium (liquid or gas) pressure within the pressure system is above or below the rated security pressure, the dish metal diaphragm within the system jumps instantaneously, thus to push the switch contact to be connected or disconnected through a connecting rod; when the pressure drops to the rated recovery value, the dish metal diaphragm is instantaneously reset and the switch is automatically reset.
 

Specialist
