Helicoid® Pressure Gauges
Helicoid pressure gauges use an exclusive cam and roller movement that reduces the wear and tear problems associated with conventional geared movements. The rolling action of the cam facing against the highly polished stainless steel roller produces minimal friction and wear. The unique back-adjust screw provides readily accessible external zero adjustment for most applications. User experience has proven that Helicoid cam and roller movements dramatically increase gauge life up to ten times over conventional geared movements. This is especially true in applications where the gauge is subjected to severe pressure pulsations and mechanical vibration. Gauge life is further extended by the careful choice of materials.
