5 Techniques to Adjust or Repair a Pressure Gauge
- Opening a vent to release pressure build-up
- Opening the Glass (or plastic cover) then removing the needle.
- Rotating the screw located at the face of the scale.

Is my pressure gauge broken?
Pressure gauge problems are one of the easier well issues to diagnose. If the PSI gauge doesn't ever move, then it is most likely broken. Another warning sign is a pressure reading when the system has no water in it. The pressure gauge is a tool that allows us to see how the system is operating.
What causes a pressure gauge to fail?
Pressure gauge failure can be attributed to one or more of these eight reasons: mechanical vibration, pulsation, extreme temperature, pressure spikes, overpressure, corrosion, clogging, and mishandling/abuse. Pressure gauges are an integral part of an application's warning system.

1. There are differences between diaphragm pressure gauges and standard pressure gauges in terms of pressure measurement principle and structure
The pressure measuring principle of the standard pressure gauge is to be calculated into the pressure measuring spring. The spring tube is under pressure, and it will produce elastic displacement and drive the connecting rod and the central gear deflection. The pointer is mounted on the main gear shaft to show the pressure measurement value.
2. Analysis of the causes of faults in the use of diaphragm pressure gauges
2.1 The diaphragm pressure gauge is distributed in the TEC boundary zone, and the failure rate
3. Diaphragm pressure gauge servicing
We have overhauled more than one diaphragm pressure gauge, and we found that most of the failures are caused by the loss of silicone oil in the spring tube. So it can be said that the spring tube filled with silicone oil solves the key problem of diaphragm pressure gauge maintenance. But to the spring tube filled with silicone oil is not easy.
4. Calibration of diaphragm pressure gauges
Our diaphragm pressure gauges are supplied from abroad with the equipment and have a standard 1/2 NPT thread to connect the pressure gauge head. In addition, each diaphragm pressure gauge is provided with a connection flange. Therefore, we want to calibrate the diaphragm pressure gauge.
5. Conclusion
The diaphragm pressure gauges are widely used in oil transmission stations for the primary measurement of operating pressure. Still, they also have the problem of being damaged and expensive to purchase new gauges.
