Presentation Transcript

• They are very simple and easy to use. Their needle gives the current reading and marking shows the current and dangerous levels. But, they are not designed to store the readings and they cannot compute details like deviation and average.

• This type of tachometer is basically a permanent magnet generator. Its output is indicated as 2 to 10 volts per 1,000 rpm. For speed indications, there is a voltmeter with a high resistance value that is built with calibration in RPM

• As the name suggests it is an alternating current tachometer, which consists of revolving permanent magnet field with a stationary winding. The voltage output and frequency which it generates remains in proportion rotation speed.

• It is simple in construction and is just a linkage of shafts, gears, and rotating weights. The output you get with it is not very accurate and it also does not indicate the direction of rotation.

• They consists of LCD or LED readout and have enough memory for storage. These are known for performing statistical operations and gives precision measurements. Digital tachometers give accurate readings in numerical form, which is far better than using dials and needles

• Where contact tachometers remain in contact with the rotating shaft, the non-contact types do not need to have a physical contact with the rotating shaft.

• They calculate the speed by measuring the time interval between incoming pulses. And, in the case of frequency, speed is calculated by measuring the frequency of the incoming pulses.
