A METHOD FOR MEASURNG THE TEMPERATURE OF RUNNING YARNS, WEBS AND THE LIKE COMPRISING IN SEQUENCE, (1) ROTATING A THERMOCOUPLE CYCLICALLY INTO AND OUT OF CONTACT WTH AN OBJECT TEMPERATURE OF WHICH IS TO BE DETERMINED IN A SENSE GENERALLY CO-DIRECTIONAL WITH THE DIRECTION OF TRAVEL OF SAID OBJECT DURING A PORTION OF EACH CYCLE OF ROTATION FOLLOWED BY EXPOSING SAID THERMOCOUPLE TO THE HEAT OUTPUT OF A REFERENCE HEATER DURING AT LEAST A PORTION OF THE REMAINDER OF SAID CYCLE OF ROTATION, (2) REMOVING SAID THERMOCOUPLE FROM CYCLIC CONTACT WITH SAID OBJECT BUT CONTINUING SAID EXPOSING OF SAID THERMOCOUPLE TO SAID HEAT OUTPUT OF SAID REFERENCE HEATER, DETERMINING THE DIRECTION AND APPROXIMATE MAGNITUDE OF HEAT TRANSFER OCCURRING BETWEEN (1) AND (2) WITH RESPECT TO SAID THERMOCOUPLE IN THE COURSE OF SAID CYCLIC CONTACT OF SAID THERMOCOUPLE WITH SAID OBJECT, ADJUSTING SAID HEAT OUTPUT OF SAID REFERENCE HEATER SO THAT SAID THERMOCOUPLE AND SAID OBJECT ARE AT SUBSTANTIALLY THE SAME TEMPERATURE LEVEL, AND THEN OBTAINING AN INDICATION OF SAID TEMPERATURE LEVEL AS A FUNCTION OF THE E.M.F. OUTPUT OF SAID THERMOCOUPLE.
