The electric contact pressure gauge is used to measure the positive and negative pressure of the gas and liquid medium which is not corrosive to copper and copper alloy. When the pressure reaches the predetermined value, the signal is sent out, and the control circuit is switched on to achieve the purpose of automatic control of the alarm.
Electrical contact signal needle in electric contact device, equipped with adjustable magnet, can increase the contact force, speed up the contact action, so that the contact reliability, eliminating the arc, can effectively avoid the instrument working environment due to frequent vibration or medium pressure pulsation caused by contact off. Therefore, the instrument has the advantages of reliable operation, long service life and large power of contact switch.
In addition to having the same function as the point contact pressure gauge, the anti vibration point contact pressure gauge is important to measure the pressure of the medium with strong pulse and the medium with violent vibration in the working environment.

Wiring principle:

To increase the intermediate relay or contactor, electric contact pressure of 1 high pressure points on the table, a point, a low voltage, current direction: line into the midpoint, after low point to normally closed relay 1 groups of contacts, to the end of the coil of the contactor relay coil, the other end is connected with the zero line. Another set of contactor on the normally open contact, the 2 end parallel to the pressure gauge low end and midpoint. The intermediate relay is controlled by the line of fire entering the midpoint of the pressure gauge, from the high voltage point to the middle relay coil section, and the middle relay coil another section connecting the zero line.
