Product Description

Select pressure value according to system pressure requirement and confirm reasonable tolerance and differential pressure



Pressure switch according to the working pressure: high pressure, low pressure, vacuum

1MPa(145PSI),

High pressure operating pressure is usually greater than 1MPa (145PSI),

1Mpa(145PSI),

Low pressure operating pressure is usually less than 1Mpa (145PSI),

0~-0.1Mpa

The working pressure of vacuum switch is 0 ~ -0.1mpa

Product Specifications
 Adopting Eng thread quick connector(copper flare connection)or brass tube welding fitting structure, flexibly setting, easy to use and no special need for mounting and fixing
 Plugging or wiring connection designed to customers choice SPST connection, normal open or normal close structure to customers choice
 Security and reliability by adopting fusion welding stainless steel pressure inductor and full air-tight connection
 Any pressure value within 3-800 PSI(0.02-55mpacan be made based on customers' requirement
 Pre-set pressure parameter before delivery allows direct use without resetting on the customers site

Operating Principle
 The series of pressure control are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing certain pressure. The electric contact opens or closes with the leader when the diaphragm moves. The switch resets automatically when induced pressure reduces below rated value

 Application
 The series of pressure control are used to the high, low pressure protection of some refrigeration system like residential, commercial automobile air-conditioner and ice maker etc. It can also be used to hydraulic pressure and steam pressure control system of all kinds of air compressor, equipment or tool and agricultural machine
Product features

Adopt quick joint of inch pipe thread or copper pipe welded structure, easy to use, flexible to install, no need of special installation and fixation;Insert type or wire type connection mode is available for users to choose at will;Single-pole single-throw switch mode, normally open switch contact structure;

 

Welded sealed stainless steel pressure inductor with steel explosion-proof enclosure, safe and reliable;

 

It can be manufactured within the pressure range of 1305PS~2610PSI(9~18MPa) according to the user's requirements. Before leaving the factory, the pressure parameters of the product have been set according to the requirements in the factory. There is no need to set any more, so it can be used directly.
