ABSTRACT:
A method and device for the error-blanking and -compensation of interference signals caused by gammagraphy in radiometric measuring systems for process measurements. The device includes, an input for measured values Lm(t)of a process variable L(t)measured by the detector, an input for at least one, non-radiometrically measured and likewise monitored, first process parameter P1=P1(t-τ), whose change leads with delay by a possible delay time τk, which can also be τk=0, to a change ΔLm=Lm(U)−Lm(0+1)of the radiometric, measured value Lm(t); an output, which is connected to a process control system, and an evaluation- and error-compensation facility, which determines during operation the change ΔLm=Lm(u)−Lm(n+1)of the radiometric, measured values Lm(n)und Lm(ti+1)registered by the detector at two, arbitrary per se, times tiand ti+1following one after the other, and, by means of the calculative relationship ΔLm=f(ΔP1), compares such with a change ΔP1=P1(ti+1−r)of the first, non-radiometrically measured process parameter in the corresponding time interval.
