Non contact heat measurement sensor

摘要

The sensor has a thermo-element (9) attached to a shield (8) to measure the actual temp. at the sensor. A further thermo-element (10), for comparison with the first unit (9), is at the centre of the sensor near its axis, and pref. on the base surface (61) of the cylindrical body (6) under the shield (8). The paired thermo-elements are connected in series with the thermo columns (3,4), with a polarity so that the heat current effect is against the signal interference in the measurement chain of the columns (3,4).
