A tachometer is an instrument that measures the working speed of an engine, typically in revolutions per minute (RPM). A tachometer is a miniature low-voltage generator. It is widely used in control system servo systems and vehicles as a transducer for producing sound signals proportional to speed.
Given below are top 5 advantages of DC tachometer:
- It has linear characteristics
- In DC tacho-generator, temperature is easily compensated
- It does not have zero speed voltage error
- It is capable to generate high voltage from small size
- The generated voltages have no undesirable phase shifts or wave shapes
