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...
