Working principle of electric contact pressure gauge

The electric contact pressure gauge is composed of a measuring system, an indicating system, a magnetic auxiliary contact, a housing, a regulator, and a junction box (plug seat). Ordinary electrical contact pressure gauges measure the positive and negative pressures of gas and liquid media that have no corrosive effect on copper and copper alloys, while stainless steel electrical contact pressure gauges measure the positive and negative pressures of gas and liquid media that have no corrosive effect on stainless steel. When the pressure reaches a predetermined value, a signal is sent and the control circuit is connected to realize the automation of the alarm.

The electric contact pressure gaugeThe axial pressure gauge flange of instrument is based on that the spring tube in the measuring system is forced to produce corresponding elastic deformation and displacement at the end of the spring tube under the pressure of the measured medium. It is enlarged and enlarged by the transmission device of the gear transmission mechanism by means of a pull rod. The indicator on the gear (together with the contact) indicates the measured value on the dial one by one. At the same time, when it is in contact with the contact (upper or lower bound) on the setting pointer (moving off or on), it will make the circuit in the control system open or close, so as to realize automatic control and signal alarm .
The electric contact pressure gauge device with adjustable magnetic steel can increase the suction force of the contact, accelerate the contact action, make the contact reliable, eliminate the arc, and effectively avoid the frequent shutdown of the instrument due to the vibration of the working environment or the fluctuation of the medium pressure . Therefore, the electric contact pressure gauge has the advantages of reliable action, long life, and large contact switch power.
