BIMETALLIC STRIP (with metal handle)

BIMETALLIC STRIP: with metal handle

• This Bimetallic Strip comprises two different metals rolled in the form of a strip – not riveted.
• Demonstrates unequal expansion of different metals when heated.
• Size dimensions: 150 x 10mm with metal handle.

(Wikipedia excerpt: ..."A bimetallic strip or bimetal strip is a strip that consists of two strips of different metals which expand at different rates as they are heated. They are used to convert a temperature change into mechanical displacement. The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. The metal with the higher coefficient of thermal expansion is on the outer side of the curve when the strip is heated and on the inner side when cooled.

The invention of the bimetallic strip is generally credited to John Harrison, an eighteenth-century clockmaker who made it for his third marine chronometer (H3) of 1759 to compensate for temperature-induced changes in the balance spring.[1] Harrison's invention is recognized in the memorial to him in Westminster Abbey, England...")
