Frequently asked questions

Common questions about Pressure Gauge from 3G Electric.

How do I choose the right pressure gauge for my application?

Start with the pressure range — select a gauge where normal operating pressure falls in the middle third of the dial. Then confirm connection size and type, wetted materials for compatibility with your media, and whether the environment requires an intrinsically safe or sealed gauge. Our team can help match specifications.

What is the difference between a standard dial gauge and an intrinsically safe pressure gauge?

Intrinsically safe gauges are designed for hazardous areas where electrical or thermal energy could ignite flammable atmospheres. They limit energy and surface temperature to safe levels. Standard dial gauges suit general industrial use. Choose based on your area classification and media.

Do you supply pressure gauge accessories such as guards and repair tools?

Yes. Our range includes gauge guards, repair tools, and sealed variants such as freeze- and clog-resistant internal seals and nickel alloy C-276 mini-seals. These help extend gauge life in demanding service. Browse the catalog or contact us for compatibility guidance.
