DIRECT DRIVE BOURDON TUBE
The advantage of Perma-CalŽ direct drive over conventional C- tube gauges is simple, there is only one moving part No gears, linkages, or springs to wear or
break. Perma-CalŽ 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 that fail most frequently). Perma-CalŽ gauges maintain their structural integrity and accurate calibration in
the most demanding environments, even during prolonged and rugged use. Perma-CalŽ direct drive pressure gauges provide the lowest cost of ownership by giving
the best value in durability, reliability, and accuracy.

NO LIQUID FILL
Perma-CalŽ gauges have more durability and longevity than liquid-filled gauges, without the mess or problems of liquid fill. Perma-CalŽ
gauges do not have any of the problems filling solves. There are no gears or linkages to lubricate, and Perma-CalŽ gauges are internally dampened with a small
application of heavy (600,000 centistokes) silicone grease that eliminates pointer flutter. Perma-CalŽ provides a longer life gauge than liquid filled gauges without the
leaking or discoloring problems of liquid fill.

SAFETY FEATURES
Perma-CalŽ gauges have a very low volume elastic element and solid front case that provide the safest gauge possible. C-tube gauges have a relatively large volume
elastic element that in cases of catastrophic failure could spill large amounts of process. Not all direct drive gauges offer the industry standard solid front for case safety. The Perma-CalŽ
configuration of solid front and rear blowout features provides the customer with the safest possible case style. Perma-CalŽ furnishes the safest, most durable gauge in the
industry.

CERTIFIED ACCURACY
All Perma-CalŽ gauges have a high repeatable accuracy, instantaneous action, and are available as Grade 3A (+.25% full scale), Grade 2A (+.5% full scale), or +.5%
mid-scale/ + 1% full scale. The full scale accuracy rating is applicable in both ascending and descending modes on all gauges, except for gauges rated 8,000 PSI and above , where the descending accuracy is +1%
of full scale. Test gauges (Grade 3A) come with a calibration certificate traceable to the National Institute of Standards and Technology (NIST) included in the price. Perma-CalŽ provides
the best in durability, reliability and accuracy.
