Product Features
Resistance remote pressure gauges are suitable for measuring the pressure of liquids, vapors, gases, and other media that do not corrode copper and copper alloys. Because a sliding resistance transmitter is installed inside the instrument, the measured value can be transmitted to a secondary instrument far away from the measurement point as an electrical value to achieve centralized detection and remote control. In addition, this instrument can also indicate pressure locally for on-site process inspection.
Structural principle
This instrument consists of a spring tube pressure gauge and a sliding wire resistance transmitter. The working principle of the mechanical part of the instrument is the same as that of a general spring tube pressure gauge. Due to the fact that the resistance transmitter system is installed on the gear transmission mechanism, when the sector gear shaft in the gear transmission mechanism deflects, the rotating arm (brush) of the resistance transmitter is also deflected accordingly. As the brush slides on the resistor, the change in the measured pressure value is converted into a change in the resistance value, which is transmitted to the secondary instrument and indicates a corresponding reading value. At the same time, the primary instrument also indicates the corresponding pressure value.
