Measuring temperature based on the use of electric or magnetic elements directly sensitive to heat {; Power supply therefor, e.g. using thermoelectric elements} using thermoelectric elements, e.g. thermocouples the object to be measured not forming one of the thermoelectric materials the thermoelectric materials being arranged one within the other with the junction at one end exposed to the object, e.g. sheathed type
