Method and apparatus for measurement by determining the temperature of a thermosensitive element heated by the joule effect
Abstract
Abstract METHOD AND APPARATUS FOR MEASUREMENT BY DETERMINING THE TEMPRATURE OF A THERMOSENSITIVE ELEMENT HEATED BY THE JOULE EFFECT UTILIZING A COMPENSATING THERMOSENSITIVE ELEMENT AND A THERMOSENSITIVE DETECTOR ELEMENT WITH THE COMPENSATING ELEMENT CONTINUOUSLY SUPPLIED WITH A DIRECT CURRENT WHILE THE DETECTOR ELEMENT IS SUPPLIED WITH SQUARE DIRECT CURRENT WAVES HAVING AN INTENSITY REGULATED TO A VALUE GREATER THAN THAT OF THE INTENSITY OF THE DIRECT CURRENT SUPPLYING SAID COMPENSATING ELEMENT. THE METHOD INVOLVES REGULATING THE DURATION OF THE SQUARE DIRECT CURRENT WAVES SO THAT THE RESISTANCE OF THE DETECTOR ELEMENT HAS THE SAME VALUE AS THAT OF THE COMPENSATING ELEMENT WHEREBY THE VALUE OF ONE OF THE VARIABLE CHARACTERISTICS OF THE SQUARE DIRECT CURRENT WAVES MAY BE TAKEN AS THE REPRESENTATIVE VALUE OF THE CHARACTERISTIC QUANTITY TO BE MEASURED.
