Frequently Asked Questions (FAQs)
Find answers to common technical queries regarding specifications, selection, calibration, and delivery.
The sensing bulb, capillary, and internal Bourdon tube are charged under pressure with pure nitrogen gas. When heat is applied to the bulb, the gas expands proportionally to temperature, causing the Bourdon tube to uncoil and move the pointer across the dial.
FGB gas-filled thermometers feature built-in bimetallic ambient compensation inside the movement case that automatically cancels out temperature variations along the capillary run.
Yes, we supply capillary thermometers with magnetic snap-action high/low alarm contacts to trip heaters or sound horns when limits are crossed.
