How To Identify A Pressure Gauge and Get the Proper Replacement?

To identify your pressure gauge and find a proper replacement, you will need to gather some information about the gauge. Here are some steps you can follow:

What material is it? Gauge cases are typically available in black-painted aluminum, stainless steel, phenolic, plastic, brass, or another material for meeting an industry specification and/or requirement.

Next is the case’s structural design. Does it have a solid front or open front? This pertains to whether the gauge does (solid) or doesn’t (open) have an integral wall incorporated into the case behind the dial face.

Most gauges do not require a solid front as most are for general pressure measurement, yet it offers additional operator safety and a more rugged enclosure if there are extreme pressure spikes that can lead to the rupturing of the gauge system.

Determine the type of pressure being measured (e.g., gauge pressure, absolute pressure, vacuum pressure). This information is usually indicated on the face of the gauge.

Note the pressure range of the gauge (e.g., 0-100 psi). This information is also usually indicated on the face of the gauge.

Identify any additional features or characteristics of the gauge, such as the type of mounting, the type of connection, or the material of construction.

Once you have gathered this information, you should be able to find a suitable replacement gauge by contacting the manufacturer or searching online for a gauge with similar specifications. It may also be helpful to consult with a pressure gauge supplier or specialist to ensure that you are choosing a compatible and suitable replacement gauge.
