Now with a new, never before seen, TEN (10) YEAR Warranty!
The Series 34 Accu-Drive test gauges represents the next generation of Direct Drive Pressure Gauges. It incorporates the 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!!
In many severe service applications, the C-bourdon containing 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, the case fill liquid causes other operational difficulties…dial discoloration and potential shift of calibration just to mention two of them..
All Series 34 Accu-Drive test 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 of 316SS. 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 size 4.5" is available as of today with a new 10 YEAR Warranty!
The combination of lower cost of ownership, long service life, maintenance-free "direct drive" technology, robust design platform and a wide array of pressure ranges makes the Series 34 Accu-Drive "Direct Drive Difference" pressure gauges from 3D Instruments the ideal choice for your demanding pressure monitoring or test and calibration applications.
