Abstract :
Electronic circuit configurations for determining the dynamic response of thermoresistive sensors, using pulsed electrical excitation step and radiation step, are presented. Experimental results obtained with these circuits are included. The reduction in the response time of an instrument with these sensors in feedback structures is experimentally demonstrated
