摘要：
A low-cost fluorescence temperature sensor using the decay-time principle has been constructed, using a milimeter size probe element, a dedicated microprocessor and simple logic circuitry with LED excitation of the material. Results in the region from minus 50 to plus 200 degree C have been reported with a approx. plus or minus 2 degree C accuracy using Q100 neodymium glass and comparisons made with commercially available sensors. Extension of the work to higher temperature measurement is discussed.
