GPF FREQUENCY TRANSDUCER

Power transducer GP&EP series power Transducer

Quick Overview

The GPF frequency transducer converts AC voltage to a linear DC output signal proportional to the frequency of the input. Employing a crystal based oscillator conversion principle, the measured frequency band is accurately represented by proportional linear DC voltage or current output.

GPF FREQUENCY TRANSDUCER

1.Introduction:

The GPF frequency transducer converts AC voltage to a linear DC output signal proportional to the frequency of the input. Employing a crystal based oscillator conversion principle, the measured frequency band is accurately represented by proportional linear DC voltage or current output.
