How to choose the right pressure gauge

　　The main types of pressure gauges are dry, digital, and glycerin filled. For many on-site hydraulic applications, glycerin-filled gauges are the best choice.

　　Why use Glycerine filled pressure gauge?

　　The glycerin in the meter can reduce the impact of sudden pressure changes. This helps protect the mechanical properties inside the meter. They are ideal for applications where "shock loads" and sudden pressure changes may occur in the system. (For example, when using a hydraulic nut separator). Glycerin pressure gauges should also be used with power pumps because glycerin reduces needle vibration-thus making the pressure gauge more readable and extending its service life.

　　Other key considerations when choosing Glycerine filled pressure gauge from a pressure gauge manufacturer.

　　What pressure range is required? – Make sure to match the pressure gauge with the working pressure. For example, reading 25 bar on a 1000 bar pressure gauge is not very accurate. In addition, pressure gauges designed for lower pressures than your application may be damaged.

　　Pressure and force-Some pressure gauges include scales that show force and pressure. For example, for lifting projects, a dynamometer can measure the load supported by a cylinder or jack.

　　Scale: both imperial and metric systems are available.

　　Required accuracy: The accuracy of the full scale is usually +/- 1.5%, but using digital meters can reach +/- 0.25%. Make sure they choose a gauge with the correct accuracy.

　　Material selection: For the shell, copper alloy is often used for lower pressure. Stainless steel is often used for high pressure. If you are working in a harsh environment, it is worth checking whether the material is suitable for use.

　　Mounting options: The gauge has a threaded mounting seat, and the options include the lower part, the rear part, and the middle rear part.

　　Thread: Make sure to select a pressure gauge with the correct thread on the mount (for example, ½ or ¼NPTF).
