The pressure switch is mainly used for high and low pressure protection control in refrigeration systems such as household, commercial, automobile air conditioners, heat pumps, ice machines, etc. It can also be applied to hydraulic and vapor pressure of various air compressors, equipment tools, and agricultural machinery.
1: Select product raw materials, and control quality from raw materials.
2: Mature production technology, each product undergoes 5 quality inspections before leaving the factory, which gives you not only the product, but also a peace of mind.
3: A strong technical team is ready to serve you and develop and customize voltage control products suitable for your equipment.
1. Single-Pole Single-Throw Automatic Reset Pressure Controller.
2. It adopts inch pipe thread quick joint or copper pipe welding type installation structure, which is convenient to use and flexible to install without special installation and fixation.
3. The plug-in or wire-type connection method is available for customers to choose at will.
4. Single-pole single-throw switch mode, normally open or normally closed switch contact structure can be arbitrarily selected.
5. Fusion-welded sealed stainless steel pressure sensor and fully sealed switch structure are safe and reliable.
6. In the pressure range of 3～700PSI (0.02Mpa～4.8Mpa), the pressure value can be arbitrarily selected for manufacturing according to customer requirements.
7. The pressure parameter of the product has been set in the factory as required before leaving the factory, no need to set it again, it can be used directly.
This series of pressure controllers mainly use the built-in stainless steel reversible action diaphragm to work in the opposite direction 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.
