It is suitable for measuring the pressure of liquid, steam and gas which does not corrode steel and copper alloy. Because a slip wire resistance transmitter is arranged inside the resistance remote transmission pressure gauge, the measured value can be transmitted to the secondary instrument far away from the measurement with electricity, so as to achieve centralized detection and remote control. In addition, the pressure gauge can also indicate the pressure on the spot, so as to facilitate the on-site work inspection.

The resistance remote transmission pressure gauge is composed of a spring tube pressure gauge and a slide wire resistance transmitter. The function of the mechanical part of the resistance remote pressure gauge is the same as that of the general spring tube pressure gauge. Since the resistance transmitter system is set on the gear transmission mechanism, when the sector gear shaft in the gear transmission mechanism deflections, the rotor arm of the resistance transmitter (brush) is also deflected accordingly, because the brush is sliding on the resistor, the change of the measured pressure value is transformed into the change of the resistance value, and is transmitted to the secondary instrument, indicating a corresponding reading value. At the same time, the primary instrument also indicates the corresponding pressure value.
Remote pressure gauge has digital remote pressure gauge, electric contact remote pressure gauge, resistance remote pressure gauge, differential remote pressure gauge, shock resistance remote pressure gauge and so on
