Since the resistance transmitter system is arranged on the gear transmission mechanism, when the sector shaft in the gear transmission mechanism deflects, the rotating arm (electric brush) of the resistance transmitter correspondingly deflects, and the change of the measured pressure value is converted into the change of the resistance value due to the sliding of the electric brush on the resistor and is transmitted to the secondary instrument to indicate a corresponding reading value; at the same time, the primary meter also indicates the corresponding pressure value. However, the existing resistance-type remote pressure gauges all adopt a double-strand double-path electric brush (fig. 6), which easily causes the defect that two paths of electric brush wires are asynchronous in operation, and is reflected in that the output resistance value of the pressure gauge is jumped and unstable, thereby influencing on-site detection and use control. Meanwhile, the electric brush of the traditional remote transmission pressure gauge is fixed on a fan gear shaft of the core, and under the environment that vibration exists at the installation position, the axial jumping gap of the core causes the defects that the electric brush is insensitive to contact with a resistance card, no output exists at the secondary instrument end and the like, so that the service life and the stability of the product are reduced.
