Temperature Gauges

PRISMA Instruments & Gauqa ^Bourdon France Bimetal Dial Thermometer The Bimetal thermometer employs a bimetal strip in the form of helix (it works on the principle of thermal expansion - two metals having different coefficient of expansions are joined to form a bimetal. The resultant expansion of bimetal is proportional to temperature). Bimetal dial thermometers are simple in construction, yet rugged. They are used for measurement of temperature in most of the industrial applications. They are offered in the range of (-) 500C to 6000C. With rigid stem having bottom or back entry. It can also...

PRISMA Instruments & Gauge J3ourdon France 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...
