The electric contact pressure gauge is equipped with a special electrical device. The pointer of the gauge can control the on or off of the electrical signal while indicating the pressure value, achieve the purpose of double-digit automatic control and alarm.
Working principle of electric contact pressure gauge: Different pointers in the gauge equipped with contacts respectively. When using, first adjust the maximum and minimum pressure setting pointers to the required pressure point position. When the pressure changes, once the indicator pointer reaches the set pressure point, the contacts on the indicating pointer will come into contact with the contacts on the setting pointer. This process will cause the circuit of the automatic monitoring device to be connected or disconnected, realize automatic control and alarm.
