DIRECT DRIVE BOURDON TUBE
The advantage of Perma-Cal DIRECT DRIVE pressure
gauges over conventional "C"-tube pressure gauges is simple,
PERMA-CAL HAS ONLY ONE MOVING PART. There are NO LINKAGES, NO
GEAR, and NO SPRING. The parts that wear out simply are not
there. Perma-Cal pressure gauges have a unique helical-wound
elastic element that is attached directly to the pointer shaft.
This eliminates the need for any movement-amplifying gears or linkages
(the parts of a "C"-tube design gauge that fail most often.)
Perma-Cal gauges maintain their structural integrity and accurate
calibration in the most demanding environments, even during prolonged
and rugged use. Perma-Cal DIRECT DRIVE pressure gauges provide
the lowest cost of ownership by giving the best value in
durability, reliability, and accuracy.

NO LIQUID FILL
Perma-Cal pressure gauges have more
durability and longevity than liquid-filled pressure gauges, without
the mess or problems of liquid fillings. Perma-Cal pressure
gauges do not have any of the problems which liquid fillings attempt to
solve. There are no gears or linkages to lubricate, and Perma-Cal
pressure gauges are internally dampened with a small application of
heavy (600,000 centistokes) silicone grease that eliminates pointer
flutter. Perma-Cal provides a longer life than liquid filled
gauges without all the leaking or fluid discoloration.

SAFETY FEATURES
Perma-Cal pressure gauges have a very
low volume elastic element and solid front case that provide the safest
pressure gauge possible.

CERTIFIED ACCURACY
All Perma-Cal pressure gauges have a
high repeatable accuracy, instantaneous action, and are available as
Grade 3A (+/- 0.25% FS), Grade 2A (+/- 0.50% FS), or +/- 0.50%
Mid-Scale, 1.0% FS accuracy. The full scale accuracy rating is
applicable in both ascending and descending modes on all gauges, except
for gauges rated at 8,000 PSI and above, where the descending accuracy
is rated at +\- 1.0% FS. Test gauges (Grade 3A) come with a
calibration certificate traceable to the National Institute of
Standards and Technology (N.I.S.T.) included in the price.
Perma-Cal provides the best in durability, reliability, and accuracy.
