Overview

The measurement system of a general ordinary pressure gauge consists of a joint and a spring tube. Due to changes in the measured pressure, the free end of the spring tube is displaced, and the pointer at the end of the fan-shaped transmission gear is driven to rotate by the connecting rod, indicating the corresponding pressure value on the dial. In order to eliminate the clearance activity of the sector gear shaft gear, a disc-shaped balance spring is installed on the shaft gear

Product Details

Ordinary pressure gaugeSuitable for measuring the pressure of liquids, vapors, and gases that are non explosive, non crystalline, non solidifying, and do not corrode steel and copper alloys.

Main technical indicators of general pressure gauges

Pressure gauges Y-60, 100, 150
Environmental conditions for use: -20~70 ℃, relative humidity not exceeding 85%
Temperature impact: When the temperature deviates by 20 ± 5 ℃, the impact error does not change by more than 0.4%/10 ℃

structural principle

The measurement system of the instrument consists of a joint and a spring tube. Due to changes in the measured pressure, the free end of the spring tube is displaced. The pointer at the end of the fan-shaped transmission gear is driven to rotate by the connecting rod, and the corresponding pressure value is indicated on the dial. In order to eliminate the clearance activity between the sector gears, a disc-shaped balance spring is installed on the shaft gear.
