Tachometers are instruments which are used to determing the speed at which something is turning [usually measured/indicated in Revolutions per minute]. There are many different tachs that accomplish this in several different ways. The tach that uses a "generator" is basically a voltmeter for the "read out," and a generator that creates a small electrical output which when supplied to [and properly calibrated to] the read out voltmeter guage, gives an indication of the Rpm of the shaft to which the generator is attached.

Why it is called as logic function generator?
this generator operates using logical function thats why is called as logic function generator
Does a generator produce ac or DC voltage?
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.
How do you polarize a 12 volt generator on 1968 VW?
Remove the fan belt.Connect a jumper from generator DF to the frame (or generator D- pole, if it exists).Pick up battery plus with a jumper cable and touch the generator D+ pole - the generator should start spinning. Do this only for a few seconds to avoid overheating. The generator is polarized now.
What does a generator hold?
A generator produces electricity. A battery holds an electrical charge.
What does it mean when rpm goes back to zero but car is still driving fine?
Your tachometer is broken.
What is the tachometer princibal?
THERE ARE TWO TYPES OF TACHOMETER. 1.D.C. TACHOMETER 2.A.C. TACHOMETER ALSO DIGITAL TACHOMETERS CAN BE CONSTRUCTED using various principles..... D.C. TACHOMETER its construction is very similar to a D.c. generator. it works on the principle of generation of emf wen a rotating conductor cuts the magnetic flux......when magnetic flux is constant then the emf produce is directly proportional to the speed of the armature that is coupled to the shaft of motor. A.C. tachometer its construction is similar to a two phase servo motor.... and works conversly of it....
What is the difference between tachogenerator and tachometer?
A tachogenerator is is an electric generator that generates a voltage that is accurately proportional to the speed of the shaft. Generating a voltage proportional to the speed is an inherent characteristic of all generators, but tachogenerators are specifically designed to provide an accurate signal over a specified range of load currents and operating temperatures. The output signal from a tachometer generator(tachogenerator) is often used to provide feedback to improve the regulation of an electric motor speed control. A tachometer is an instrument that measures and displays rotational speed. An electric tachometer combines the tachogenerator with a voltmeter that has the dial marked to show speed rather than voltage.
How do you install a tachometer on a 1991 mercury cougar?
Remove the instrument panel cover. Remove the tachometer retaining screws. Remove the tachometer cable from the back of the tachometer. Reverse the process to install the new tachometer.
How do you measure the RPM of motor shaft?
you need a tachometer
How does a DC generator used as a tachometer work?
Here we will just connect DC generator shaft with motor's rotating spindle. Now connect voltmeter across dc gen. and just calibrate voltmeter in terms of rpm. If you have worked with micro-controllers then it will be very easy using it's ADC input.
Mazda b2500 tach works speedometer does not?
The Mazda tachometer and the speedometer have separate cables. The tachometer cable probably does not work properly. Change the tachometer cable.
What causes the tachometer to stop working on a 1991 Acura Legend?
The tachometer cable may be faulty. The tachometer sensor, on the side of the engine might not be functioning properly.
Where can I buy a used portable tachometer?
You can perhaps buy a used portable tachometer by going on to www.amazon.com
Where can I buy a handheld tachometer?
Here's a site where you can buy a handheld tachometer: http://www.checkline.com/tachometers/
How do you install an after market tachometer on a 1999 Mercury Cougar?
you dont need to cause it has a factory tachometer
What is the difference between an auto-meter and a tachometer?
A tachometer and an auto-meter is an instrument measuring the rotation speed of a car or a motor. An auto-meter is more accurate and reliable than a tachometer.
What is needed to install a tachometer in a dunebuggy with a 1970's vw motor?
a tachometer, wire and wire terminals
