Electric contact pressure gauge is used to measure the positive and negative pressure of gas and liquid media that do not corrode copper and copper alloys. When the pressure reaches a predetermined value, it sends a signal and connects the control circuit to achieve automatic control alarm.
An adjustable permanent magnet is installed on the electrical contact signal pin of the electric contact pressure gauge device, which can increase the suction force of the contact, accelerate the contact action, make the contact reliable, eliminate the arc, and effectively avoid frequent disconnection of the instrument due to working environment vibration or medium pressure pulsation. So the electric contact pressure gauge has the advantages of reliable operation, long service life, and high contact switch power.
