Introduction of remote pressure gauge:
It is suitable for measuring the pressure of liquid, steam and gas and other media that are not corrosive to steel and copper alloys. Because a sliding wire resistance transmitter is set inside the resistance remote pressure gauge, the measured value can be transmitted to the secondary instrument far away from the measurement in the form of electricity, so as to realize centralized detection and long-distance control. In addition, the pressure gauge can indicate the pressure on the spot, which is convenient for on-site work inspection.
Basic description:
1. It is suitable for measuring the pressure of liquid, steam, gas and other media that are not corrosive to steel and copper alloys. Because a sliding wire resistance transmitter is set inside the resistance remote pressure gauge, the measured value can be transmitted to the secondary instrument far away from the measurement in the form of electricity, so as to realize centralized detection and long-distance control. In addition, the pressure gauge can indicate the pressure on the spot, which is convenient for on-site work inspection.
2. The environmental conditions for the use of the meter: -40 to 60 °C, the relative humidity is not greater than 85%, and the vibration and the rapid pulsation of the measured (control) medium should have no obvious impact on the normal operation of the meter.

Structural principle:
This resistance remote pressure gauge is composed of a spring tube pressure gauge and a sliding wire resistance transmitter. The mechanical part of the resistance remote pressure gauge
The function is the same as the general spring tube pressure gauge. Since the resistance transmitter system is set on the gear transmission mechanism, when the gear transmission mechanism is
When the sector gear shaft of the
The change of the measured pressure value is transformed into the change of the resistance value, which is transmitted to the secondary instrument to indicate a corresponding reading value. At the same time, once
The gauge also indicates the corresponding pressure value.
Remote pressure gauges include digital remote pressure gauges, electrical contact remote pressure gauges, resistance remote pressure gauges, differential remote pressure gauges, shock-resistant resistance remote pressure gauges, etc.
