Construction:
The bimetallic thermometer comprises of a bimetallic strip by bonding together two thin strips of two dissimilar metals. The differential alter in elaboration of the two metals results in bending of the bimetallic strips with alter in temperature.

Working:
The bimetallic strip has one end fixed and the temperature changes causes the free end to deflect. The range of linear kinship amid deflection and temperature depends on the combining of metal used. Invar alloy is a low elaboration material. The other metals used may be steel, monel and brass.

The deflection of the free end is directly proportional to the temperature change and the length of the strip and is inversely proportional to the thickness of the strip.

If one end is fixed, the deflection of the free end is direct indication of the temperature measured. the sensitivity of the thermometer is increased by increasing the length of the bimetallic strip.

The size pf the thermometer may be made little by having the bimetallic strip arranged as the circular spiral or as an helix.

The temperature range that may be measured is -40 degree Celsius to +550 degree Celsius. The accuracy is within +or-0.5% to +or-2%.

Uses:
used in ambient temperature measurement devices.
Used to air-conditioning thermostats
Used in oil refineries.
used in Tyre Vulcanizers.
Used in hot work wire heaters.
Used in tempering tanks.

Advantages
Simple, robust and inexpensive.
It has good accuracy.
It may measure temperature in the range of (-40 to 550) in Celsius.
It may withstand 50% overage temperature measurement.

Disadvantages
Not commended for measurement of temperature above 550 degree Celsius.
The metals undergo permanent warp distortion.
Usage is fixed to local mounting.
