Working principle of stainless steel bimetal thermometer
Bimetal thermometer is a single needle thermometer that uses a spiral tube shaped bimetal sheet which is fixed at one end and connected with a pointer needle at the other end. It rotates with the change of temperature and drives the pointer to rotate to indicate the temperature.
