Vibration Dampening Improves Pressure Gauge Reading

Bourdon tube pressure gauges can exhibit rapidly oscillating indicators when subjected to pulsations from the measured line. The fast moving pointer on the dial face makes it impossible for an observer to obtain an accurate reading from the gauge. One solution has been to fill the case with a viscous liquid that served to dampen the vibration. While this is generally effective, it does create an additional potential maintenance burden related to the liquid.

A better solution is a dry gauge with a suitable means of dampening pointer oscillations that rivals that of liquid filled gauges. Winters Instrument, a manufacturer of industrial instrumentation on a global scale, offers a range of pressure gauges with their StabilZR™ dampened movement that provides liquid filled performance in a dry gauge.

The short video included with this post compares a standard dry gauge, liquid filled, and StabilZR™ versions. You can see the performance difference.
