Resistance remote transmitting pressure gauges are used to measure on steel and copper alloy can not afford the corrosive liquid, steam and gas medium pressure.
Technical index
Accuracy level: 16
Transmitter starting resistance value: 30 ~ 20Ω
Transmitter value: 340 to 400Ω
The external voltage of the transmitter is not more than 6V
For remote transmitting pressure conditions: - 40 to 60 DEG C, relative humidity is not more than 85% and vibration and measured (or controlled) medium rapidly fluctuating ohmmeter
There was no significant effect on the normal work of the instrument.
Temperature effect: the use of temperature deviation from 20 to 5℃ degrees Celsius, the temperature of the additional error is not greater than 0.4%/10
Structure principle
The resistance remote transmitting pressure table is composed of a spring tube pressure gauge and a sliding line resistance transmitter composed. Resistance remote transmitting pressure mechanical watch part
The function is the same as the common spring tube pressure gauge. Because the resistance transmitter system is arranged on the gear transmission mechanism, the gear transmission mechanism is provided with a transmission mechanism.
When the sector gear shaft of the gear shaft is deflected, the rotating arm (electric brush) of the resistance transmitter can also be deflected correspondingly, and the electric brush slides on the resistor,
Which makes the measured pressure value changing resistance value changes, and transmit to the secondary instrument, indicating a corresponding readings. At the same time, once
The instrument also indicates a corresponding pressure value.
