Liquid Filled Dial Thermometer


Liquid filled system 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. Generally used where mercury type thermometer is not used in industries such as Food, Pharmaceutical, etc. The main advantage is its minimum immersion length required for sensing (as low as 30mm suffices for proper sensing thereby making it ideal for installing in lower line sizes) 


Rugged construction Rigid stem or capillary type Suitable for pharmaceutical, food, biotechnology industry. Protection class IP-67 Accuracy ± 1% FSD Minimum immersion length (as low as 30 mm suitable for lower line sizes possible) Case compensated system
