A method for the contactless temperature measurement, as well as a detector head for the contactless temperature measurement

摘要

A detector head for contactless measurement of a body (114)with a plurality of heat radiation detectors (111, 211), each of which a heat radiation sensitive detector surface (110) have,the article 34 detector surfaces (110) essentially on one surface of a body (114) are aligned, the surface temperature is to be determined,the heat radiation detectors (111, 211) have in each case a signal delivery unit for the output of a detector signal, which is a measure of the surface temperature, whereby no focusing optical system is provided, and wherein one adder for adding at least two detector signals is provided to form a sum signal,characterized by the,that the heat radiation detectors (111, 211) on the outside of a cone (126, 426) are arranged andthat the heat radiation detectors (111, 211) radiation filter for eliminating a the body (114) are assigned to be heated radiation.
