• As the media temperature increases, the capillary fill fluid vaporizes, increasing pressure in the Bourdon tube to activate the movement and pointer for proper indication
• Brass, stainless steel, or phenolic case
• Dry or liquid filled
• Bottom, back or lower back connected
• The dial scale graduations are non-linear, therefore the highest degree of accuracy and readability is found in the upper half of the scale
