- A. Thermocouples
- B. Bimetallic thermometers
- C. Thermostats
- D. Relays for opening & closing of electrical circuits
Explanation
A thermocouple generates voltage from the junction of two dissimilar metals and does not use a mechanically deflecting bimetal strip. Bimetal strips are instead used in thermometers, thermostats, and switching relays.
