Abstract (en)
[origin: WO03052396A2] The invention relates to methods and devices for erasing errors and compensating interference signals caused by gammagraphy in radiometric measuring systems according to process measuring techniques. The inventive device comprises an input for measuring values Lm(t) of process variables L(t) measured by the detector, an input for at least one non-radiometrically measured and optionally monitored first process parameter P1 = P1(t- tau ), whereby the modification thereof leads to a delay in a modification of DELTA Lm = L(tj) Lm(tj + 1) of the radiometric measuring value Lm(t), amounting to a delay time tau k, which can also be tau k = 0; an output which is connected to a process control system, and a detection and error compensation device, which when an operational measuring mode determines the modification DELTA Lm = L(ti) Lm(ti + 1) on the basis of radiometric measuring values Lm(ti) and Lm(ti + 1) detected by the detector at two consecutive random times ti and ti+1 and a comparision is effected by means of the mathematical interrelation DELTA Lm = f ( DELTA P1,) with respect to a modification DELTA P1 = P1(ti - tau ) P1(ti+1- tau ) of the first non-radiometric measured process parameter detected in the corresponding time interval.
