The development of resistance remote transmission pressure gauges requires' seeking victory while maintaining stability '
Resistance remote transmission pressure gaugeThe measured value is transmitted to a secondary instrument far away from the measurement point as an electrical value through the sliding resistance transmitter inside the instrument, in order to achieve centralized detection and remote control. In addition, the resistance remote transmission pressure gauge can simultaneously indicate the pressure on site (for easy on-site process inspection). This instrument can also be connected to a diaphragm isolator (isolation body) to make a resistance remote transmission diaphragm pressure gauge, which can measure the pressure of highly corrosive, viscous, and easily crystallizable media. 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.
The resistance remote transmission pressure gauge consists of a spring tube pressure gauge and a sliding line resistance transmitter that is functionally related to the measured pressure. The working principle of the mechanical part 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 instrument also indicates the corresponding pressure value.

Structure principle of resistance remote transmission pressure gauge
The resistance remote transmission pressure gauge consists of a spring tube pressure gauge and a sliding line resistance sensor. When the measured pressure changes, the spring tube end produces displacement. On the one hand, the pointer indicates the corresponding pressure on the dial through the transmission system, and on the other hand, it drives the electric brush to slide on the resistance, converting the change in measured pressure value into a change in resistance value, and transmitting it to the secondary instrument to indicate the corresponding pressure.

The transmitter is converted into a mA signal based on changes in the diaphragm box.
Resistance remote transmission pressure gaugeSuitable for measuring the pressure of liquids, vapors, gases, and other media that do not corrode copper and copper alloys. Because a sliding line resistance transmitter is installed inside the resistance remote transmission pressure gauge, 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, the resistance remote transmission pressure gauge can also indicate the pressure on site for easy on-site process inspection of the resistance remote transmission pressure gauge.
