Pressure Gauges

Pressure gauges are analogue instruments used to measure the pressure or vacuum within a fluid power system. Gauges are installed at any point within a machine where the pressure needs to be measured. By monitoring the pressure within a system you are able to prevent damage or down-time caused by spikes in pressure.

Analogue pressure gauges display pressure on a dial. The needle is controlled by a spring or a tube which changes according to the pressure. It is important to ensure that your dial is capable of reading the pressure range within your system. Some pressure gauges can read up to 5000 psi or 7500 psi. Pressure scale range is also measured in "bar".

Other things to consider when choosing a pressure gauge include the operating temperature and the accuracy of the reading. Most gauges are mounted on a threaded connection, such as G 1/4 or BSP 3/8.

What are pressure gauges made from?

Most standard pressure gauges are made from stainless steel or brass. However, there are lightweight alternatives such as plastic or aluminium options.
