Advantages of
Gearless, Direct Drive Gauges
Direct Drive performs in any environment and is ideal for those experiencing vibration, pulsation and shock.
The primary advantage of Direct Drive Pressure Gauges over conventional C-tube gauges is simple, there is only one moving part.
Perma-Cal gauges feature a unique helically-would Bourdon tube attached directly to the pointer shaft.
No gears, linkages, or springs to wear or break.
This provides a very linear reading gauge that maintains its accuracy, and eliminates the need for any movement-amplifying gears or linkages (the parts of a C-tube type gauge 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.
Additionally, Perma-Cal gauges withstand a 50% overpressure without shift in calibration.
