As the name implies, a bimetallic strip is a specialized component formed by bonding together two metal strips with different coefficients of thermal expansion. When the ambient temperature changes, the differing rates of thermal expansion and contraction between the two metals cause the strip to bend or deform; this characteristic makes it an ideal choice for temperature sensing.
Bimetallic strips play a pivotal role in various temperature controllers, thermocouples, and temperature switches. They accurately detect temperature fluctuations and convert these changes into mechanical displacement or electrical signals, thereby enabling automatic temperature control and monitoring.
