Temperature-Frequency Conversion Circuit is an indispensable part of radio telemetry temperature circuit. The principle of Temperature-Frequency Conversion Circuit is to convert the change of temperature to the change of voltage and use changing voltage to control the change of the oscillating frequency of oscillatory circuit. The changing frequency then is sent by wireless after signal encoding. After the sent signal is received by receiving set, the changing frequency would restore as value of temperature and display via the screen after demodulating, converting and decoding. The diagram of Temperature-Frequency Conversion Circuit composed of CD4046 is as shown in the picture.
