Thirty years of industrial application have proven that our Direct Drive design is vastly superior to the C-bourdon tube/movement system incorporated in traditional pressure gauges, especially for applications that experience high vibration and/or pulsation.
Liquid-Free Cases for Improved Performance
In many severe service applications, C-bourdon pressure gauges are filled with silicone to both dampen needle movement as well as lubricate their metal movements to extend service life. Besides adding additional cost to the price of the pressure gauge, this filler liquid causes other operational difficulties such as dial discoloration and a potential shift of calibration.
Series 25 pressure gauges’ “direct drive difference” technology applies silicone dampener directly to the bourdon tube. This “coil dampening” approach isolates the pointer from vibration and pulsation, thereby eliminating the need for a liquid-filled gauge case.
