THERMOSRESISTIVE RADIOMETER WITH ANALOGUE COMPENSATION OF AMBIENT TEMPERATURE
Analog Temperature Compensation, Termorresistive Radiometer, Wheatstone Bridge.
The radiometers are devices used by measure incident energy by area. It’s useful for wide applications like solar radiation, chemical uv treatment, skin cancer prevention, atmosphere research, etc. A class of radiometers is thermoresistive sensor based and work by electrical compensation principle. The sensor are heat up to a constant temperature by electromagnetic waves absorption and by the joule effect. This type of radiometer is susceptible a significant uncertain in measurement due floating of environment temperature. This work bring up the hypothesis
of convert the constant temperature of operation point into floating operating temperature. For that, is propose a change in standard Wheatstone bridge setup
