Tachometers |
|
TACHOMETER [tachometer] , is an instrument that
indicates the speed, usually in revolutions per minute, at which
an engine shaft is rotating. Some tachometers, especially those
used in automobiles, are similar in construction and operation
to automotive speedometers . Other types, often connected
directly to the shaft whose speed they indicate, are small
electric generators whose output voltage is proportional to
speed. This voltage is applied to a voltmeter whose dial is
calibrated in speed units. Another type, used only with engines
having an ignition system, operates by counting the pulsations
of current or voltage in the ignition system, the number of
these being proportional to the speed of the shaft. |
