The Series 34 Accu-Drive process gauge represents the next generation of Direct Drive pressure gauges. It incorporates 3D Instruments’ signature "Direct Drive Difference" Inconel helical bourdon tube system.
Direct Drive Pressure Gauge Technology
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 Direct Drive pressure gauge designs are 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, 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: dial discoloration and potential shift of calibration, to name just two.
Quality Materials & Durable Construction
All Series 34 Accu-Drive process 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.
Theextremely 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. 4.5” dial sizes are standard.
The combination of lower cost of ownership, long service life, maintenance-free Direct Drive pressure gauge technology, a 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.
