Jan 24, 2023 · A pressure gauge is an instrument that measures the pressure of a gas or liquid relative to the atmosphere, a vacuum, or the difference between two points. Understanding the pressure gauge meaning helps in comprehending the instrument's function and significance in various applications.
May 14, 2021 · Pressure gauges must be serviced on a regular basis to ensure that they offer accurate and dependable pressure readings. Aside from frequent calibration, pressure gauges require little maintenance.
- Select the Right Gauge. Before you pull out a wrench, first make sure you have the right type of gauge for the application. The pressure gauge you choose must be the correct one for the
- Apply Force on Wrench Flats. Once you’ve chosen the correct gauge, pay attention to how you install the gauge. Rather than turning the case by hand, use an open-end wrench and apply force to the wrench flat.
- Seal the Deal. Notice the type of threads on the gauge before you seal it. If the gauge has parallel threads, seal it using sealing rings, washers, or WIKA sealing rings (crush rings).
- Use a Clamp Socket or Union Nut with Straight Thread. When tapered threads are used, the installer has the luxury of adjusting the gauge even after sufficient torque has been applied.
- Types of Pressure Gauges. For more detailed information on types of pressure gauges read How to Select Pressure Sensors. Differential pressure is measured by reading the difference between the inputs of two or more pressure levels.
- Pressure Gauge Specifications. Working pressure range is the maximum allowable pressure at which a system or piece of equipment is designed to operate safely.
- Scale Specifications Criteria. Scale Type. The scale is located on the face of the analog pressure gauge. Scale can help determine accuracy, with smaller scales leading to more accurate readings.
- Sensor Technology. For more detailed information on sensor technologies read How to Select Pressure Sensors. Mechanical deflection uses an elastic or flexible element to mechanically deflect with a change in pressure, for example a diaphragm, Bourdon tube, or bellows.

Jul 15, 2019 · Pressure gauge calibration can be performed through a variety of methods, including using a pneumatic/ hydraulic test pump (with an appropriately ranged and highly accurate reference gauge) or a pressure deadweight tester.
How to calibrate a pressure gauge? There are two main methods of pressure gauge calibration. Comparison to another more accurate and calibrated pressure gauge. This could be analogue or digital. The pressure medium could be a fluid, such as oil, or a gas, such as air or nitrogen. Advantages: Generally a very portable system; Faster calibration
