1.Introduction:

The FPF type frequency transducer uses the latest electronic circuit to generate a standard frequency with a quartz crystal, and converts the difference after comparison with the input frequency into a DC analog power output. Using quartz crystal and drift-free digital circuit, the frequency transmitter has high accuracy, good temperature performance and stable and reliable operation.

The DC output of the transducer is proportional to the change of the input measured frequency, and the frequency offset with the center frequency of 50Hz and 60Hz can be accurately measured. And high-resolution frequency measurements can be made over a narrow frequency range. The input and output of this type of transmitter have more specifications for users to choose, and it is convenient to cooperate with the indicating instrument and RTU.
