This paper describes the design, construction and testing of a special oven developed by us to characterize fluorescent-decay temperature sensors. The oven is designed to hold sensitive materials of different type, shape and dimensions, and is equipped with a fibre-optic system to convey the pumping and the emission radiation to and from the sensitive specimen. The results obtained over the temperature range -20 to 200-degrees-C show an oven temperature stability of +/- 0.03-degrees-C (at 3-sigma level) and a temperature uniformity of +/- 0.03-degrees-C over the specimen. A transducer based on an Nd:glass phosphor, excited by a laser diode, is calibrated against a platinum resistance thermometer in order to assess the oven performance. A transducer resolution (sensor plus electronics) of +/- 0.2-degrees-C for temperatures between -20 and 100-degrees-C results.

Abstract
This paper describes the design, construction and testing of a special oven developed by us to characterize fluorescent-decay temperature sensors. The oven is designed to hold sensitive materials of different type, shape and dimensions, and is equipped with a fibre-optic system to convey the pumping and the emission radiation to and from the sensitive specimen. The results obtained over the temperature range -20 to 200-degrees-C show an oven temperature stability of +/- 0.03-degrees-C (at 3-sigma level) and a temperature uniformity of +/- 0.03-degrees-C over the specimen. A transducer based on an Nd:glass phosphor, excited by a laser diode, is calibrated against a platinum resistance thermometer in order to assess the oven performance. A transducer resolution (sensor plus electronics) of +/- 0.2-degrees-C for temperatures between -20 and 100-degrees-C results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
