In this paper we are introducing a new inductive sensor for temperature measurement in induction heating industries and simulation of a colpitts oscillator circuit that produces an inversly varying frequency output, according to the inductance value of the induction coil is done in LABview software. LABview is a software virtual instrumentation tool in which hardware configuration is possible. The oscillator circuit is coupled with the software by using Arduino kit. Different types of contact and non contact temperature sensors were analysed. We have done a comparison and analysis of contact temperature sensors like thermistor, RTD, thermocouple and the non contact sensor like infrared sensors. It was found that high frequency oscillators can be used to detect the frequency variations in the induction heating device. Colpitts oscillator was found more suitable for the detection of frequency variations, so we have selected the colpitts oscillator for this purpose. The colpitts oscillator have the frequency range of 20KHz to 300MHz.
