DESCRIPTION■Model:
S3-FD : Accuracy：0.2%RON3-FD: Accuracy：05%RO
S3-FD transducer to measure power frequency and provide a DC
output directly proportional to the change of input within the
specified span. The input signal is shapped to square
wave by the wave shappers circuit. The duty cycle of the
square wave is change with the frequency of the input signal.
Then the square wave is fed into an integrated circuit and
the produced DC output is proportional to the
input frequency.
