Resistance remote pressure gauges are used to measure the pressure of liquids, vapors and gases that do not corrode steel and copper alloys. Because a sliding line resistance transmitter is set inside the instrument, the measured side value can be transferred to the secondary instrument far away from the measuring point with the electric value, so as to realize centralized detection and remote control. In addition, the instrument can also indicate pressure on the spot for on-site process inspection.

Structure principle

 

The meter consists of a spring tube pressure gauge and a resistance sensor with a sliding line.

 

The mechanical part of the instrument works on the same principle as the spring tube pressure gauge. The resistance transmitter is set on the gear transmission mechanism, so when the gear drive mechanism in the sector gear deflection of the shaft resistance transmitter derrick (brush) accordingly to deflection, also because the brush on the resistor, makes the change of the measured pressure value transformation for the change of the resistance, and spread to the secondary instrument, indicating a corresponding reading values. At the same time, a gauge also indicates the corresponding pressure value.
