1. Due to the instantaneous pulse increase of the measured medium, the pointer of the instrument is pushed below the stop position,
2. The instrument pointer will not zero after the pipeline or equipment is depressurized,
3. In addition, the instrument fan teeth may experience wear and tear after working for a period of time,
The movement of the instrument is the heart component of the pressure gauge, and more than 80% of instrument damage is due to movement damage causing the instrument to be unusable. Now, I have solved the problem of instrument jumping by adding limit screws to the existing movement,
1. Add isolation plates to solve the problem of instruments not returning to zero position
2. Widening of the separated fan-shaped teeth solves the problem of instrument contact surface and provides wear resistance to extend the service life.
