product overview

A pressure display control gauge with a magnetic memory switch pointer, which not only has the function of measuring liquid and gas pressure gauges, but also has the ability to send pressure signals. The pressure gauge is changed to a magnetic pointer on the base of the pressure gauge; An additional layer with a magnetic memory switch pointer is added on top of the magnetic pointer, which can be arbitrarily adjusted to a certain pressure scale value on the dial. When the pressure changes and the magnetic pointer rotates to the magnetic memory switch pointer, the contact of the magnetic memory switch pointer moves to emit a pressure signal with magnetic memory. This pressure display control table has high accuracy in indicating pressure, simple and convenient pressure signal setting, and high flexibility, making it suitable for various self-control systems.

Magnetic memory function. When the magnetic head moves parallel to the magnetic memory contact point and reaches a certain point within the range of magnetic coupling between the two parties, the magnetic memory contact point will act. Moreover, when the magnetic head continues to move in the original direction and leaves the magnetic memory contact point, the contact point still maintains the memory state of action. Only when the magnetic head moves in the return direction and passes through the contact point until the magnetic coupling is released, the magnetic memory contact point will be reset to its original state. So, when the magnetic head moves back and forth relative to the magnetic memory contact, it can emit signals for the contact to move in and out.

The magnetic memory switch developed by our company is based on the above principle. It is operated by the change of magnetic field and is widely used as a position detection sensor in automation systems such as mining, machinery, light industry, metallurgy, chemical industry, textile, etc. This utility model has the advantages of normally open, normally closed with directional memory, large control distance and non-contact control of magnetic steel, and reliable operation.
