If the pressure gauge pointer falls off, it will lose its most basic function, the reasons for the pointer falling of the pressure gauge may be:
1. After the pressure gauge is calibrated, the pointer is not installed firmly;
2. Improper handling during transportation will cause large vibrations, it may also cause the pressure gauge pointer to fall off.
3. Increasing or releasing pressure too quickly causes the pressure gauge pointer to repeatedly hit the stop pin and fall off;
4. The instrument is in an environment with large amplitude and high frequency, long-term work causes the pointer to fall off.
5. There is a defect in the pressure gauge itself, which causes the pointer to fall off easily.
After determining the cause, appropriate measures can be taken. Timely processing or replacement, avoid affecting pressure monitoring.
