Application

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 industor and full air-tight connection.
Any pressure value within 3~667PSI(0.02Mpa~4.6Mpa) can be made base on customers' requipment.
Pre-set pressure parameter before delivery allows direct use without resetting on the customers'site.

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

With screw quick coupling or copper tube welded structure, it is flexibly installed and easily used with no special installation and fixing mode.
Insert and wire-type electrical connectors can be selected by users.
Unipolar single-throw or unipolar double-throw, normally open or normally closed switch contact structure optional for users, sealed stainless steel sensor safe and reliable.
