Usage description:
The YTZ-150 resistance remote pressure gauge is 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 values can be transmitted as electrical values to a secondary instrument far away from the measurement point, achieving centralized detection and remote control. In addition, this instrument can also indicate pressure locally for on-site process inspection.

Main technical indicators:
○ Accuracy level: 1.6
○ Starting resistance value of transmitter: 3-20 Ω
○ Full resistance value of transmitter: 340~400 Ω
○ Wiring diagram of sliding resistance transmitter

○ Environmental conditions for use: -40~60 ℃, relative humidity not exceeding 85%, and vibration and rapid pulsation of the measured (controlled) medium should not have a significant impact on the normal operation of the instrument.
○ Temperature effect: When the temperature deviates by 20 ± 50 ℃, the additional temperature error shall not exceed 0.4%/10 ℃.
○ Weight: 1.2kg

Structural principle:
The YTZ-150 resistance remote transmission pressure gauge consists of a spring tube pressure gauge and a sliding wire resistance transmitter, etc
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.
