RANGE OF EXPERIMENTS TO BE CARRIED OUT :

• To Study and use Dial Type Thermometer.

TECHNICAL DESCRIPTION :

A bimetal thermometer uses a bimetal spring as temperature sensing element. This technology uses a coil spring made of two different types of metals that are welded or fastened together. These metals could include copper, steel or brass as long as one has low heat sensitivity while the other metal has high heat sensitivity. Whenever the welded strip is heated, the two metals change length based on their individual rates of thermal expansion. Since the two metals expand to different lengths, the bimetallic strip is forced to bend or curl towards the side with a lower coefficient of thermal expansion. The movement of the strip is used to deflect a pointer over a calibrated scale which then indicates temperature to the user.
