Series 34 Pressure Gauge
3D Instruments’ new Series 34 direct drive pressure gauges provide that vital check even in the worst applications. You know the ones... applications that result in pressure gauges with off-zero pointers, missing or broken pointers, or worn pressure systems. Typically, these problems are caused by vibration or pulsation. The single sensing element in a 3D Instruments Series 34 direct drive pressure gauge withstands vibration and dampens pulsation.
The Direct Drive Difference
By itself, a single gauge can be an inexpensive component. However, you may require a number of gauges for safety and reliability. Our direct drive gauges are designed with only one moving part—a helically-wound Bourdon tube manufactured from Inconel® X-750. This flexible material prevents the coil from losing its shape, thus ensuring accuracy. With no additional mechanical components that are vulnerable to wear, a 3D Instruments direct drive gauge lasts longer than C-shape bourdon tube gauges.
With the need for less maintenance time and fewer replacement parts, choosing the Series 34 Pressure Gauge for the right (or worst) applications can reduce your total cost of ownership and extend the life of the instruments that gauge the health of your operation.
You don’t need a high end pressure gauge for every application, but you may need one of our gauges for your mission-critical applications. Place a 3D Instruments Series 34 direct drive gauge in your most stressful applications and see what we can do for you.

Give Us Your Worst
Series 34 Accu-Drive pressure gauges represent the next generation of Direct Drive Pressure Gauges. They incorporate 3D Instruments’ signature "Direct Drive Difference" Inconel helical bourdon tube system. The "direct drive" concept 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 one! Thirty years of industrial application have proven that this design is vastly superior to the C-bourdon tube and movement system incorporated in other pressure gauges...especially for vibration and pulsation.
For many severe service applications, C-bourdon pressure gauges are filled with silicone to both dampen needle movement and lubricate their metal movements to extend service life. Besides adding additional cost to the price of the pressure gauge, the case fill liquid causes other operational difficulties, such as dial discoloration and potential shift of calibration.
All Series 34 Accu-Drive pressure gauges utilize the finest materials of construction. The bourdon tube is constructed on Inconel, a highly elastic material with excellent corrosion resistance. The wetted parts are made of 316 stainless steel. The balance of the gauge hardware is designed to minimize corrosion associated with challenging field environments. The extremely robust bourdon tube system offers outstanding overpressure protection to 150% of full scale on pressure ranges from vacuum to 10,000 psi.
Various case styles are available with measurement accuracy available ranging from a 0.5% "process" gauge version to a 0.25% full scale "test" gauge version. Dial sizes of 4.5" are available, with a new, never before seen 10 Year Warranty!
