Utility pressure gauges are very common, commodity product
with most if not all manufacturers having their gauges made in countries in
the Pacific Rim region, such as China, Taiwan and India. These type of gauges are used by OEM's for compressed air and water systems
which do not require significant accuracy (3-2-3%) or longevity; the
environment in which they are installed tends to be non-corrosive and dry.
This type of gauge will last longest when the pressure remains
relatively constant; if your application has continuous pressure
fluctuations you would be better served with a
liquid filled gauge
The connections of utility pressure gauges are made from a copper alloy and the cases
are painted steel, plastic, plated steel or SS cases.
These are not considered to be
an "industrial grade" pressure gauge, but if
this is what you need we can provide them at a competitive cost and usually
ship from stock.
