PRESSURE GAUGE FAQS

Common questions about pressure gauges

Practical answers to help you choose the right pressure gauge, accessory, or calibration instrument for industrial, HVAC, refrigeration, process, and high-pressure applications.

What pressure gauge do I need?

The right pressure gauge depends on the pressure range, media type, temperature, vibration, environment, and required accuracy. General industrial systems often use standard pressure gauges, while corrosive, hygienic, steam, refrigeration, or high-vibration systems may require a specialised gauge or accessory.

When should I use a liquid-filled pressure gauge?

Liquid-filled gauges are commonly used where vibration, pulsation, or pressure fluctuation causes needle movement. The fill helps stabilise the pointer, improve readability, and reduce wear on the internal gauge mechanism.

What is a diaphragm seal used for?

A diaphragm seal isolates the pressure gauge from harsh, corrosive, viscous, crystallising, or high-particulate process media. It helps prevent clogging, contamination, and damage to the gauge internals.

What pressure gauge is suitable for steam?

Steam applications usually require a pressure gauge used with a syphon. The syphon creates a condensate barrier between the live steam and the instrument, helping protect the gauge from excessive heat.

What is the difference between a differential pressure gauge and a duplex pressure gauge?

A differential pressure gauge measures the pressure difference between two points, such as across a filter or pump. A duplex pressure gauge shows two separate pressure readings on one dial using two independent pressure systems.

Can pressure gauges be customised?

Yes. Many pressure gauges can be supplied with custom dials, dual scales, coloured sectors, red set pointers, company logos, special wording, mounting options, and accessories such as snubbers, syphons, diaphragm seals, or electrical contacts.

Do you supply digital pressure gauges and calibration instruments?

Yes. ATS supplies digital pressure gauges and reference recorders for pressure testing, calibration, commissioning, maintenance, and industrial field measurement applications.
