Application

---

General
our series pressure controller (also called pressure switch) is a more advanced mini controller in the world and is researched and designed by using special material and process on the basis of absorbing and digesting technical advantages of same kinds of product both at home and abroad. The properties of the product are reliable and its installation and application are very convenient. It is wide used for heat pump, oil pump, gas pump, refrigeration set of air-condition and equipment where needs to adjust medium pressure itself and pressure protection.

Principle of Work
When the lift of pressure to be controlled in the system is over the set value, the pressure in the system will drive mini butterfly metallic film and produce instant displacement and push inch switch to off (or on) and take place over voltage protection.When the pressure of medium to be ontrolled is low than the set value, the mini film sheet will be jumped towards opposite direction and restore its original state and inch switch is off (or on) and take place over voltage protection.
