(Tachymeter); The tachometer division on the dial of a chronograph serves to measure the speed, e.g. of a car on a measured course of 1 km or 1 mile. At the moment the car passed the starting point of the course, the chronograph is set and stopped at the final point of the course. The position of the stopped hand on the tachometer scale corresponds to the speed in km (miles) per hour. The speed over the whole test run must be the same.

Displays, the number of 'Revolutions Per Minute' (RPM) of the engine.

Function that measures the speed at which the wearer has traveled over a given distance. The scale is calibrated to show the speed of a moving object over a known distance. The standard length on which the calibration is based is shown on the dial - ex: 100, 200 or 1,000 meters.

(1) A small ac or dc generator, sometimes referred to as a rate generator, that converts its shaft speed into an electrical output. The tachometer is frequently used in servo-systems to sense the velocity of a load. (2) An instrument that measures the rate at which a shaft is turning.

A device that can measure engine speed in revolutions per minute RPM.

An instrument for measuring the speed of engine rotation (RPM).

A device used to indicate the speed of the engine in rpm (revolutions or cycler per minut). The tachometer is mounted on the dahboard or the steering wheel. It helps the driver to know the optimum rpm for changing gears on manual transmissions. A tachometer is also a diagnostic device which a mechanic uses to determine idle speed and other carburetor and running settings. Also called a "rev counter".

It is an indicator of the number of revolutions per minute at which the engine is turning.

A device which measures the revolutions per minute of a revolving shaft. To tach means to measure speed with a tachometer.

An instrument drivers use to determine engine speed and performance. It measures the number of revolutions per minute.

Itsâ€(tm) an instrument that shows how fast the engine is running.

Instrument for measuring speed. In watchmaking, a timer or chronograph with a graduated dial on which speed can be read off in kilometres per hour or some other unit (see timer).[ Back to the top

An instrument used to measure engine speed in revolutions per minute (rpm). It can be used to support proper shifting of a manual transmission.

A feature of some chronograph watches for measuring the speed traveled over a measured distance. Also known as ?Tachometer?.

An instrument that indicates the revolutions per minute (RPM) of the engine.

An instrument for measuring revolutions of a shaft, used on band machines to indicate band speed in surface ft. per min. (sfpm).

1. instrument for measuring velocity and giving revolution per minute as indication; 2. name given to a counter for indicating the number of propeller revolutions per minute

A device that measures rotational speed in revolutions per second.

Speedometer or revolution recorder on bezel.

A small generator normally used as a rotational speed sensing device. Tachometers are typically attached to the output shaft of DC or AC inverter motors requiring close speed regulation. The tachometer feeds its signal to a control which adjusts its output to the DC motor or AC inverter motors accordingly (called "closed loop feedback" control).

An electromagnetic feedback transducer providing an analog voltage signal proportional to rotational speed.

A digital Tachometer provides very precise speed sensing to assist in producing the highest possible degree of DC motor speed regulation, linearity and repeatability. Acrison SCR controllers that provide a 50:1 drive turndown ratio, or those used in conjunction with Acrison weigh feeders, utilize a Tachometer for speed feedback data. The Tachometer is directly connected to the output shaft of the DC motor, through a specially designed gear-reducer.

an instrument which measures the working speed of an engine, typically in revolutions per minute.

A long-standing method of collecting information about a vehicle's journey, mainly used in heavy goods vehicles (HGVs). It records the times the vehicle is active and plots its speed on a graph against time (the tachograph).

An optical sensor designed specifically to count light impulses through a turning propeller and read out the engine RPM.

A gauge that measures how fast an engine is spinning. The measurement is usually expressed in revolutions per minute. Also: "tach."

Function measuring the speed at which the wearer runs over a given distance. The tachometer scale is calibrated to show the speed of a moving object, such as a vehicle, over a known distance. The standard length on which the calibration is based is always shown on the dial, e.g. 1,000, 200 or 100 meters, or - in some cases - one mile. As the moving vehicle, for instance, passes the starting-point of the measured course whose length corresponds to that used as the basis of calibration, the observer releases the chronograph hand and stops it as the vehicle passes the finishing point. The figure indicated by the hand on the tachometer scale represents the speed in kilometers or miles per hour.

Measures engine RPM.

A device for measuring the number of times a shaft rotates, usually calibrated in "revolutions per minute," abbreviated "rpm." The most common use of this in modeling is to measure motor speed. Most model tachometers operate optically, by being pointed at the rotating propeller.

A device for measuring engine rpm. Many cars with manual transmissions have a dashboard tachometer to aid in changing gears. A portable tachometer is used to adjust idle speed as part of a basic tune-up. Often, a tachometer is combined with a dwell meter in a single unit called a tachldwell meter.

This sits on the instrument panel and shows the speed that the crankshaft is rotating at in RPM (revolutions per minute) to give a measure of how hard the engine is working.

the measurement scale that determines the speed at which the wearer of the watch has traveled over a measured distance.

An instrument for measuring the speed of a rotating shaft or a moving vehicle.

A timer or chronograph with a graduated dial or bezel which enables you to measure a vehicles speed per hour. The figure indicated by the tachometer scale graduation is calculated on the basis of one kilometer or one mile. This is done by measuring the time elapsed over a fixed distance.

An instrument that measures the speed of rotation, usually in RPM.

Non-recording instrument which indicates the speed of an engine in RPM; or, simply, a speedometer that measures RPM instead of MPH; helps driver to select gear steps that will keep the engine operating within the proper speed and pouter range.

An Instrument to indicate rotational speed, usually calibrated in RPM (revolutions per minute).

An instrument for measuring the speed of a rotating device, such as a motor.

A tachometer gauges the speed of rotation of a shaft or disk (from Greek: tachos = speed, metron = measure), as in a motor or other machine. The device usually displays the rate of revolutions per minute on a calibrated analog dial, but digital displays are increasingly common.
