The
Direct Drive Difference
Replacing the antiquated
C shape Bourdon Tube in our Pressure Gauges is a unique
Helically Wound Bourdon, The
Direct Drive Difference. Our Bourdon
coil is coupled directly to the shaft-pointer, the only
moving part.
Fewer parts, fewer problems.
Regular recalibration is eliminated because there are
no complex wear-prone parts. Linearity is built-in;
no span adjustment is necessary - ever. And 3D accuracy
is maintained throughout the useful life of the gauge,
many times longer than those old fashioned designs.
The 3D Direct Drive design
gives instant response while resisting pointer pulsation.
Overpressure? Even 150% of full scale will not affect
the accuracy of most 3D gauges. And it takes pressures
of 500% greater than dial range to result in sensing
coil rupture. Even when subject to abuse, 3D Direct
Drive gauges last longer.
All 3D Pressure Gauges
use the finest materials in construction. We construct
our Bourdon Tube of Inconel X-750. This is a highly
elastic material with excellent corrosion resistance.
All other wetted parts are in 316SS. All materials are
selected to be compatible with your most challenging
applications.

The
3D Helical Bourdon Tube
The heart
of the 3D Pressure Gauges are the Helically wound Inconel
X-750 Bourdon Tube. Inconel was chosen because of its
excellent resistance to corrosion and its elasticity.
There are two types of helical Bourdon tubes: one is
specifically designed for higher pressures and the other
is designed for lower pressures. Each pressure range
dictates subtle differences in Bourdon tube design and
manufacturing method.
To the user
the benefits of this painstaking high technology process
are longer field life with inherent accuracy and span.
As an assembly in the 3D Test or Process gauge our coil
provides lower cost of ownership and easier field use,
simply because our gauges do not fail or require recalibration.

Vs. Liquid Filled Gauges In Many Severe Applications
In many
severe applications C-shape Pressure Gauges cases are
filled with silicone liquid to dampen their movements
and increase service life. Beside adding cost to the
gauge, the liquid fill causes other problems. These
are associated with loss of liquid fill, discoloration,
and added maintenance difficulties.
In most
instances a standard 3D TLG "Tough Little Gauge" can
replace an old fashioned liquid filled gauge. Beside
being less expensive, the 3D gauge will provide longer
service life and much less field complications for your
instrument personnel. Even against liquid fill, 3D gauges
can last as much as ten times longer in severe services
with pulsation or vibration. This has a dramatic effect
on your cost of ownership. After all, 3D Bourdon Tube
Pressure Gauges are designed to work, and work for a
long time no matter what the application.
