Indicates media temperature using a temperature-actuated liquid in the sensing element and a highly accurate, high quality pressure gauge
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
