3D Instruments has long been known as a manufacturer of the innovative Direct Drive Difference range of gauges. The range excels in the following areas High Accuracy test gauges Robust, accurate process gauges ideal for high vibration & other challenging applications, backed up with a 6 year warranty Depth & Caisson Gauges used the world over Innovative digital gauges Portable test & calibration equipment

Direct-Drive Technology provides the basis for long-lasting life and performance for any application. The single sensing element - Inconel X750 Bourdon tube - forms a simple, yet reliable foundation of durability, vibration resistance and pulsation dampening. The helically wound Bourdon tube eliminates the "moving part" weaknesses of standard "C-type" designs because there is only one working part and fewer moving parts translates into fewer problems. The absence of complex, wear-prone parts eliminates the need for regular re-calibration and linearity is built-in - no span adjustment is necessary - ever. Consequently, Direct-Drive gauges remain accurate and last longer than standard "C-tube" pressure gauges.

PARALLAX REDUCTION SYSTEM

3D Instruments, LLC has developed a two pronged approach to reduce parallax error in readings with 3D's PRS (Parallax Reduction System).

1. Highly polished mirror bands 2. Knife edge pointer The combination of these features allows the reader of the pressure gauge to know the exact pressure reading - when the needle reflection disappears under the needle, the reader can be confident of the reading.
