Series 25 Pressure Gauge

3D Instruments’ Series 25 Accu-Drive pressure gauges incorporate our signature “direct drive difference” Inconel helical bourdon tube system. Our direct drive technology couples the bourdon tube directly to the shaft-pointer, thereby streamlining the design and reducing the number of moving parts from approximately twelve down to just one.

Advantages of Direct Drive Technology

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.

The Right Pressure Gauge for Any Application

Series 25 Accu-Drive gauges can accommodate pressure ranges from vacuum to 20,000 psi (varies by model). All Series 25 pressure gauges are overpressure protected to 150% of full scale.

Various case styles are available, with measurement accuracies ranging from 0.5% “Process” gauge models to 0.25% full scale “Test” gauges.

Reduced Maintenance & Longer Working Life

In most instances, a standard 3D Accu-Drive pressure gauge can directly replace an “old fashioned” liquid-filled gauge, providing reliable performance without the maintenance headaches cited above.

When compared to liquid-filled gauges, Accu-Drive gauges have been shown to last as much as ten times longer in applications with extreme pulsation and vibration. The net effect of these benefits, coupled with a six-year product warranty, is a dramatic reduction in your cost of ownership.

And, with no gears or wear points, our Accu-Drive gauges maintain their rated accuracy over the entire life of the gauge, without the need for costly periodic recalibration.

Manufactured from Premium Quality Materials

Series 25 Accu-Drive pressure gauges utilize the finest materials of construction. Gauge cases can be either ABS or 300 Series stainless steel. Bourdon tubes are constructed of Inconel, a highly elastic material with excellent corrosion resistance. All other wetted parts are 316 stainless steel.
