Correction method for pressure gauge pointer not returning to zero

2024-11-29190 have been browsing

If the pressure gauge pointer cannot return to zero when there is not pressurization, you can remove the pointer of the pressure gauge, re-fix it so that the indication is at zero position. Take the current initial position as the zero point to achieve pressure gauge zero point adjustment.

 

If the above adjustment methods still do not work well, It may be that the firmware inside the pressure gauge is loose, Changes in the position of the internal parts of the pressure gauge, causes the pressure gauge pointer to indicate an increase or decrease. In this case, it is necessary to reposition the firmware under standard pressure and fix it to restore the pointer to accuracy, Make the pressure gauge accurate again. Pay attention to handing over repairs to professionals.

 

If the pressure gauge load pressure is too large, this causes the spring tube, the elastic element of the pressure gauge, to deform in an irreversible manner. There will also be a phenomenon where the pointer does not return to zero, the pressure gauge needs to be replaced in time.
