Pressure Gauge

Series 25 - 3D Instruments (3D Instruments)

The Series 25 Accu-Drive pressure gauges incorporate the 3D Instruments signature "direct drive difference" Inconel helical bourdon tube system. The "direct drive technology" 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/movement system incorporated in the traditional pressure gauges...especially for vibration and pulsation!!
