Liquid filled Dial Thermometer based on liquid (other than mercury) expansion principle is used for measuring temperature ranging from (-) 300C to 2500C. It has faster response and the same is available in rigid stem as well as capillary type for remote sensing. Every angle type can be offered in all SS construction.
The main advantage is its minimum immersion length required for sensing (as low as 30mm suffices for proper sensing thereby making the Liquid filled Dial Thermometer ideal for installing in lower line sizes).
Main applications of the Liquid Filled Dial Thermometers:
Generally used where mercury type thermometer is not used in industries such as Food, Pharmaceutical...
