- In various electrical applications, a dynamometer is a measuring instrument in which a pointer is deflected
as a result of the force exerted between fixed and moving coils, the
pointer being attached to the latter. It has applications in ammeters,
wattmeters, and voltmeters.
- Various types of mechanical dynamometer are used to measure the power output of a machine or of the force
of muscular contraction. A small hand-held dynamometer may be used to
record the strength of a patient's grip. A special optical dynamometer
measures the actions of the muscles controlling the shape of the lens
of the eye. The term torque meter is used to describe
a device for measuring the power of rotating engines.
