Pressure Gauge

Pressure gauges measure the pressure of liquids or gases in a system, displaying the reading on a calibrated dial. Used across compressed air lines, hydraulic systems, water circuits and industrial process equipment, they give operators and engineers continuous visibility of system pressure without interrupting operation. The range at The Hosemaster covers standard dial sizes and pressure ranges suitable for most industrial and commercial applications. All gauges are supplied ready for installation with standard BSP connections.

Pressure gauges for system monitoring and process control

Specifying the right pressure gauge is more straightforward than it sounds, but there are a few things worth getting right. The pressure range is the first one. A gauge running near its maximum reading is harder to read accurately and more likely to fail early — hydraulic shock and pressure spikes put more stress on the bourdon tube or diaphragm. A gauge with a range roughly twice your normal working pressure gives you useful headroom and keeps the needle in the readable part of the scale.

The connection position matters for installation. Bottom entry gauges suit panel mounting and most inline installations. Back entry is preferred for panel-mounted instruments where the connection needs to come through from behind. Most gauges in this range use standard BSP threads, which simplifies installation in UK pipework.

For hydraulic applications or systems with pulsating pressure, a glycerine-filled gauge is worth specifying. The glycerine damping reduces needle movement, makes readings easier to take and significantly extends gauge life in demanding conditions.

Frequently Asked Questions

What is a pressure gauge used for?

A pressure gauge monitors the pressure of a gas or liquid in a system, displaying the reading on a graduated dial. They're used across compressed air systems, hydraulic circuits, water mains, boilers, process equipment and anywhere system pressure needs to be monitored in service.

What pressure range should I choose?

As a general rule, choose a gauge whose full-scale range is approximately twice your normal working pressure. This puts the working reading in the middle of the dial where accuracy is highest, and gives headroom for pressure spikes without pegging the needle.

What connection size do your pressure gauges use?

Most gauges in this range use standard BSP (British Standard Pipe) connections. Check the individual product listing for the specific connection size and type.

Can pressure gauges be used with hydraulic oil?

Yes, provided the gauge is specified for hydraulic service. Check the product description for media compatibility — some gauges are suitable for oil, water and air; others are rated for specific media only. A glycerine-filled gauge is often recommended for hydraulic applications to dampen needle movement caused by pressure pulses.
