Solutions to common problems in using pressure gauges

Thread Content

In daily use, pressure gauges often encounter the following problems: 1. The fan-shaped teeth of the pressure gauge tend to wear out after being in use for a while. 2. Due to a sudden increase in pulses of the measured medium, the instrument pointer was pushed below the stopper. 3. The gauge pointer does not return to zero after the pipeline or equipment is depressurized. In response to the above issues, the engineers at Chengfeng Instruments shared the following corresponding solutions: 1. Widening the fan-shaped teeth on the release plate to increase the contact surface area and enhance wear resistance, thereby extending its service life. 2. The movement of a gauge is its core component; over 80% of gauge malfunctions occur due to damage to the movement, rendering the gauge inoperable. By adding limit pins to the existing movement, the problem of gauge step-jumping has been resolved. 3. Add isolation spacers to resolve the issue of the instrument not returning to zero.
