3D Instruments Direct Drive Vs. Liquid Filled Gauges
many severe applications “C-shaped” pressure gauge cases
are filled with a liquid to dampen their movements and increase service
life. Besides adding cost to the gauge, the liquid fill causes other
problems... loss of accuracy, discoloration and added maintenance difficulties.
3D applies a high viscosity silicone dampener, known as GAD, directly
to the outer layers of the bourdon tube. This GAD dampens the pointer
movement in severe vibration and/or pulsation based applications thereby
eliminating the need for liquid fill. In most instances a standard 3D
Accu-Drive Gauge will easily replace a traditional liquid filled gauge.
The 3D gauge will provide longer service life and lower field maintenance
costs. When compared to liquid filled gauges, 3D gauges can last as
much as 10x longer in severe vibration and pulsation service. Using
3D Accu-Drive Gauges will have a dramatically favorable impact on your
gauge cost of ownership!!
