Abstract

PURPOSE:To make it possible to perform measurement stably and not influenced by the concentration of a powder liquid by performing sampling intermittently and sample-holding the maximum or minimum value of varying outputs of infrared light and smoothening its results. CONSTITUTION:At preset time intervals, the sampling time and reset time are set, maximum value or minimum value of the output of infrared light quantity emitted from a powder liquid that varies at random is sample-held and the temperature of the powder liquid is measured from the value obtained by flattening the sample-held results. When, for example, a radiation thermometer 3 is used to measure temperature at one point near the discharge hole III of a pipe 1 as shown by the broken line V suitable measuring cycle T and reset period DELTAt are provided to sample-hole the peaks, a, b, ... of the curve. In this way an output that maintains a set value is obtained, and this output is passed through a means that has a large time constant such as a smoothing circuit and it is changed into an output with extremely little variation, and stable measurement can be obtained.
