Description
ENDURANCE AND REPEATABILITY
Inconel X-750 + Helical Bourdon Tube = DURABILITY
An Inconel X-750, Gearless, Helical Bourdon Tube provides repeated cycling without fatigue. Additionally, no linkages, springs or gears means there are no mechanical components to wear or break.
TRUSTED ACCURACY
Accuracy is 25% less affected by temperature fluctuations.
Inconel Elastic Element = Low Coefficient of Thermal Expansion
Inconel in combination with a low internal volume means that the impact of temperature on accuracy is significantly less than competitors using a Stainless Steel Bourdon Tube.
TYPICAL APPLICATIONS
Perma-Cal® caisson gauges incorporate a Helical Bourdon Tube sealed within a capsule.Unlike standard pressure gauges which indicate the pressure relative to the ambient environment, Caisson Gauges indicate the pressure relative to the pressure within the capsule.
- Hyperbaric chambers
- Decompression chambers and more...
