Product Specifications
Single cut double thrower switch mode, double circuits commutate automatically 1 2
Security and reliability by adopting fusion welding stainless steel pressure inductor and full air-tight
connection.
Adopting Eng. thread quick connector (copper flare connection) or brass tube welding fitting structure
Plugging or wiring connection designed to customers' choice.
Any pressure value within 3~800 PSI (0.02~5.5MPa) can be made based on customers' requirement.
Pre-set pressure parameter before delivery allows direct use without resetting on the customers' site.
Typical Outline Drawing
Operating Principle
The series of pressure switches are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing a certain pressure. The electric contact (H) opens and electric contact (L) closes simultaneously when the diaphragm moves. When the system pressure reduces, the diaphragm resets instantly, with the function of which, the electric contact
disconnects from contact (L) and connects with contact (H) automatically.
Application
The product is mainly used in refrigeration system of air-conditioner and precise pressure control system; It can also be used as the precise high-low pressure protection of variety of equipments and tools.
Designed Parameter
Working pressure range: 3~800PSI(0.02~5.5MPa)
Burst Pressure: 5000PSI
Ambient temperature: -30ºC~+80ºC
System medium temperature: -50ºC~+120ºC
Life cycles under the rated electric current:
30,000 times, 50,000 times and 100,000 times optional
Electrical Rating: At 24Vac, normal electric capacity: 125VA At 120/240Vac, normal electric capacity: 375VA
Dielectric Strength: Between disconnected contacts: AC700V/S Terminal to outer shell: AC2000V/S
Safety proof pressure: The pressure that the control can endure while not affects the rated motion value
| The highest range of working pressure | Safety proof pressure |
| <145PSI(1MPa) | 250PSI(1.7MPa) |
| 145PSI(1MPa)~400PSI(2.75MPa) | 600PSI(4.1MPa) |
| >145PSI(2.75MPa) | 800PSI(5.5MPa) |
Electric Theory Drawing
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.
