Upgrade to Direct Drive
Lower Cost of Ownership • No Liquid Fill
Customizable • Extreme Durability
It's time to upgrade to Direct Drive if...
• you're tired of leaky or discolored liquid-filled gauges
• you want to lengthen your calibration certification cycles
• you want to save money by using mini diaphragm seals
• your gauges fail due to pulsation and vibration
• you want to reduce your ongoing cost of ownership
• within 2 years your gauges require replacement
Only One Moving Part
No Gears • No Linkages • No Springs • No Liquid Fill
Perma-Cal® gauges feature a unique helically-wound Bourdon tube attached directly to the pointer shaft. This design is otherwise known as Direct Drive. Having only one moving part minimizes the effects of shock, vibration, pulsation and wear. Our gauges contain none of the primary culprits contributing to the premature failure of C-Tube gauges.
Greater life equals lower costs
Only one moving part means Perma-Cal® gauges can cycle often 1,000,000 times or more without shift in calibration. Saving time saves money. Re-certify as you see fit, not out of necessity. A longer re-certification cycle combined with greater life equals significant cost savings over time.
Priced competitively versus C-Tube and approximately 20% below our nearest direct drive competitor, Perma-Cal® gauges are the greatest value in the industry.
Design a gauge from scratch that meets your performance requirements, or simply add your logo or custom artwork to any of our available dials. Regardless, we are here to build a gauge that suits your needs and solves your pressure measurement problem.
Reliable in the Most Rugged Environments
Perma-Cal® Gauges offer superior performance on the most demanding applications.
