DEFINITION

Classification: 374/187

Mechanical (e.g., expansion or contraction of material):

(under subclass 100) Subject matter wherein the quantitative temperature determination is given by a variation of force, position, or motion caused by a variation in a temperature-responsive mechanical property of a sensing material.

(1) Note. Such mechanical properties include expansion or contraction.
