How does a bimetallic strip work
WebDec 7, 2001 · One of the electrodes is a bimetallic strip that bends when it is heated. The small amount of heat from the lit bulb bends the bimetallic strip so it makes contact with the other electrode. With the two electrodes touching each other, the current doesn't need to jump as an arc anymore. WebWhen a steel strip is combined with either a copper or a brass strip, the combination responds to heating by bending in the direction of the lesser coefficient of thermal …

WebDefinition: A bimetallic strip works on the principle of thermal expansion, which is defined as the change in volume of metal with the change in temperature. The bimetallic strip … WebDisadvantages of bimetallic strips. It is limited to applications where manual reading is acceptable, e.g. a household thermometer. It is not suitable for very low temperatures because the expansion of metals tend …
WebWhen a steel strip is combined with either a copper or a brass strip, the combination responds to heating by bending in the direction of the lesser coefficient of thermal expansion. With applied heating, the structure bends toward the steel. Bimetallic strips … WebAt normal room temperature, the two strips have the same length. However, since brass expands (or contracts) more than iron when its temperature is raised (or cooled), the bimetallic strip will bend one way or another depending on the temperature being above or below room temperature.
WebThe bimetallic thermometer uses the bimetallic strip which converts the temperature into the mechanical displacement. The working of the bimetallic strip depends on the thermal expansion property of the metal. The thermal expansion is the tendency of metal in which the volume of metal changes with the variation in temperature.
