3D Gauges operate on the direct drive principle. The pressure gauge has only one working part—a helically-wound Bourdon tube made of Inconel® X-750, a flexible material that prevents the coil from losing its shape and ensures accuracy. With no additional mechanical components vulnerable to wear, a direct drive gauge lasts longer than a C-shape Bourdon tube gauge.Watches & Gauges
