  "term": "Deformation thermometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A class of thermometers that operates on the principle that a change in temperature causes a predictable physical deformation in a sensing element. This category includes bimetallic thermometers, where two bonded metals with different expansion coefficients bend, and Bourdon tube thermometers, where a sealed, curved tube straightens as the internal fluid expands. The magnitude of the deformation is calibrated to a temperature scale.",
