Pressure Gauge
The Ashcroft ® Duragauge ® pressure
gauge is the finest production gauge on
the market for industrial use where pre-
cise indications are required. The prod-
uct line offers a wide variety of case
styles, Bourdon tubes and pressure
ranges to meet your application needs .
With the component combinations
available in the Duragauge gauge line,
over ten million variations are possible
to serve the needs of all types of indus-
tries, including process, power, nuclear,
aerospace and cryogenics.
The Duragauge gauge offers the
same outstanding quality and crafts-
manship which have characterized all
Ashcroft products since Edward
Ashcroft introduced the Bourdon tube
pressure gauge to American industry in
1852. It is built for long life and sus-
tained accuracy under the most
adverse operating conditions.
Uncompromising standards have
been established for all incoming mate-
rials used in Ashcroft products, with
dimensional details, material selection
and design carefully scrutinized. Tubing
used in manufacturing Bourdon tubes
must meet stringent standards, more
restrictive than ASTM material specifi-
cations. Throughout production, quality
assurance procedures are adhered to,
including assembly inspection, and criti-
cal laboratory examination.
Product integrity is assured through
continual monitoring of pressure ele-
ment quality. Every Bourdon tube sys-
tem is subjected to a leak test at a pres-
sure above the top of its range. Com-
puter programs yield Bourdon tube
designs with minimum stresses, assur-
ing the long life and sustained accuracy
demanded of Ashcroft products.
In the engineering breakdown lab, a
variety of tests are run continually on
Duragauge Bourdon tube systems,
such as pulsation, burst, vibration, wear,
and friction tests on movements.
Care and attention are given to every
product from its inception to final
assembly. The end result- thoroughly
engineered instruments that assure the
user a product that is precise, depend-
able and durable.
Ashcroft has pioneered the field of
gauge manufacture in research and
product integrity since the Bourdon tube
was introduced to American industry.
