DIRECT DRIVE BOURDON TUBE
The advantage of Perma-Cal® 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-Cal® 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-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® gauges have more durability and longevity than liquid-filled gauges, without the mess or problems of liquid fill. Perma-Cal® gauges do not have any of the problems filling solves. There are no gears or linkages to lubricate, and Perma-Cal® 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 gauge than liquid filled gauges without the leaking or discoloring problems of liquid fill.

SAFETY FEATURES
Perma-Cal® 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-Cal® configuration of solid front and rear blowout features provides the customer with the safest possible case style. Perma-Cal® furnishes the safest, most durable gauge in the industry.

Perma-Cal Digital Pressure Gauges

Perma-Cal Digital Pressure Gauges SELF CONTAINED
DIGITAL PRESSURE GAUGE


The Perma-Cal® Model 800 Digital Pressure Gauges are stand alone devices (with internal pressure sensor) that feature Grade 4A accuracy in a standard 1/8 DIN case size. Table top and panel mount configurations are available in 0 - 30 psi through 0 - 200 psi and metric equivalents. Compound and Differential pressure ranges are also available. The gauge complies with the new ASME B40.7 specification.
