ABSTRACT:
A temperature to frequency converter includes two temperature detectors having an electrical characteristic, such as resistance, that varies proportionally with sensed temperature. These devices are connected into an oscillator circuit that provides an electrical signal output having a frequency inversely proportional to sensed temperature. An amplitude control feedback loop connected to the oscillator circuit maintains the amplitude of the output signal constant.
