in f to V converter, input is frequencies . Is that electrical or Mechanical frequency?
To convert a frequency to a voltage, you need an electronic frequency (voltage varying in time).
One can use different types of transducers to get an electronic frequency from a mechanical one.
National makes a chip, LM2917, just for this application. Check out the typical application picture here where you can see the transducer (magnetic pick up).
sensor transduces electrical frequencies?
how to convert this frequency to mechanical frequency(RPM),,,
i ve seen a design before, they use scmitt's trigger before f to V converter
i think schmitts dont sense the frequency...(no magnetic pick up)?????
LM2917 only detect positive peak of sinusoidal wave?
