ANSI/IEEE impulse tachometric dynamo symbol
IEEE-library impulse tacho form for a speed sensor that outputs pulses at a rate set by shaft speed.
In plain English
What does ANSI/IEEE impulse tachometric dynamo mean?
The impulse form represents a speed device that turns a measured quantity into a signal whose output is a pulse train, for example a magnetic pickup reading gear teeth or a pulse generator on the shaft. The receiving device counts pulses, so the number of pulses per revolution is the scaling factor that must accompany the symbol.
A simple example
Pulse transducers may be passive magnetic pickups with amplitude rising with speed, or active sensors needing a supply. The symbol does not distinguish these, so supply wiring and input type at the receiver should be checked separately.
What the drawings help you do
Record pulses per revolution for scaling. Check whether the sensor is passive or needs a supply. An impulse device that turns a measured quantity into a signal outputs a pulse rate; a tachometric dynamo outputs an analogue voltage.

How to read it
- Record pulses per revolution for scaling.
- Check whether the sensor is passive or needs a supply.
Information to show or reference
- State pulses per revolution
- Show sensor supply if active
- Use screened cable to the counter input
A distinction that matters
An impulse transducer outputs a pulse rate; a tachometric dynamo outputs an analogue voltage.
