Perma-Cal Pneumo and Test Pressure Gauges

For gauges not listed in the pull down menu, please reference the Amron International 2011 Catalog - Page 84 or the Perma-Cal Part Builder Document located in the Attachments tab.

Features

• Inconel X-750 helically wound sensing element that has no mechanical moving parts
• Withstands a 50% overpressure without going out of calibration
• Outstanding for vibration, pulsation and shock environments
• Internally dampened to reduce pointer flutter during vibration
• Flange models available in six colors for color coding of ranges or test panels
• Rugged and safe ABS high impact plastic case with solid front - blow out back - the safest design
• Very small internal volume, a safety feature in case of misapplication or catastrophic failure
• Internal, replaceable 316 SS filter snubber
• Standard 316 SS stems and fittings

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 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.
