Flotech Solutions claims the 3D in the name of its 3D Instruments panel mounted pressure gauges stands for “direct drive difference”, referring to an inconel Bourdon tube in the form of a helix capillary, directly coupled to the pointer needle, which moves over a 270 degree scale.

These gauges use an anti-vibration helix to stabilise readings, and accuracy is unaffected by 150% overpressure. They also maintain calibration of 80% of scale swings.
