ISEN variable switch

Used for pressure protection. Patented design improved reliability. Compact design and full range of products.

Application

-The series of pressure switch is 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 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.

-Security and reliability by adopting fusion welding stainless steel pressure inductor and full air-tight connection

-. Life test can reach 250,000 cycles.

-Any pressure value within -0.05Mpa~5.2Mpa can be made based on customers’ requirement.

-Pre-set pressure parameter before delivery allows direct use without resetting on the customers’ site.

- Patented design improved reliability.

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.

Designed Parameter

-Working pressure range: -0.05Mpa~5.2Mpa

-Burst Pressure: 34.5Mpa (5000PSI)

-Ambient temperature: -35°C~+135°C

-System medium temperature: -50°C~+135°C

-Electrical Rating: At 24Vac, normal electric capacity: 125VA

                   At 120/240Vac, normal electric capacity: 375VA

1,Why use ISEN Pressure switch

 

l  Patent design (Supper Disc Assembly) improved stability of the pressure switch’s performance, especially at extreme working condition. Excursion of operation pressure is up to 65% lower than normal design.

l  Special E-welding process improved the contact and strength of the lead wire joint.

l  CE, CCC and CRCC certified product.
