TASIMER
Ta*sim"er, n. Etym: [Gr. -meter.] (Physics)
Definition: An instrument for detecting or measuring minute extension or
movements of solid bodies. It consists essentially of a small rod,
disk, or button of carbon, forming part of an electrical circuit, the
resistance of which, being varied by the changes of pressure produced
by the movements of the object to be measured, causes variations in
the strength of the current, which variations are indicated by a
sensitive galvanometer. It is also used for measuring minute changes
of temperature. T. A. Edison.
