Product Details
Features
It adopts inch pipe thread quick joint or copper pipe welding type installation structure, which is easy to use and flexible to install without special installation and fixation.
The plug-in or wire-type connection mode is available for users to choose at will.
The single-pole single-throw switch mode, normally open or normally closed switch contact structure can be arbitrarily selected.
The welded sealed stainless steel pressure sensor and fully sealed switch structure are safe and reliable.
The minimum vacuum pressure value can reach 15in.Hg (inches of mercury)
Within the pressure range of 15 in.Hg～8PSI (-0.1～0.05 MPa), the pressure value can be arbitrarily selected for manufacture according to user requirements.
The pressure parameters of the product have been set in the factory according to the requirements before leaving the factory. There is no need to set it again, and it can be used directly.

working principle
This series of pressure controllers are mainly manufactured by using the built-in stainless steel reversible action diaphragm that can be reversed after sensing a certain pressure. When the diaphragm moves, a guide rod will drive the electrical contacts to close or open. When the induced pressure drops below the recovery value, the switch can automatically reset.
use
It is mainly used for the protection of various refrigeration equipment low pressure systems whose protection pressure is negative pressure (lower than normal atmospheric pressure), and can also be used for the control of pneumatic, hydraulic and lubricating oil systems.
