Abstract :
In this paper, study of theory and technique experiment has done about noncontact fluorescence temperature detection technique. This system is particularly adapt to the temperature measurement in the rang of 0°C to130°C. The calibration graph was shown to be highly reproducible when the probe is temperature cycled. A change in drive current from 5 to 30mA yields a spectral shift of the peak emission of only a few nanometers. The drive current to the LED can easily be kept within the required narrowly defined bounds through the control circuitry. This system has resolved the temperature measurement problem in special environment and electromagnetic interference environmental.
