Photometric process measurement arrangement and a photometric measurement method

Abstract

A photometric process measurement arrangement and a photometric measurement method. The invention refers to a photometric process measurement arrangement (10) comprising a photometric immersion probe (20) comprising a photometer flashlight source (61) for providing photometric light impulses, a photometric detector arrangement (70) comprising a separate wavelength-selective detection element (71, 72, 73), and a photometer control (80) controlling the photometer flashlight source (61) and the detector arrangement (70), The photometer control (80) comprises: An impulse signal integrator (819, 829, 839) for integrating the electric impulses having the impulse intensity (Ui) generated by the detection element (71, 72, 73) of one impulse integration cycle (204; 221; 264), a measurement cycle control (90) for adapting the total number of 20 integrated cycle impulses of an impulse integration cycle (204; 221; 264) to the impulse intensity (Ui) of the single electric impulses, an A/D-converter (81, 82, 83) for converting the voltage of the impulse signal integrator (819, 829, 839) in an optional compulsory A/D conversion interval (100) after the impulse integration cycle (204; 221; 264), and an A/D-conversion management module (150) for balancing the total number of A/D conversion intervals (100-111) within a time frame (F), whereas the number of supplementary A/D conversion intervals (101-111) after the compulsory A/D conversion interval (100) depends on the length of the corresponding impulse integration cycle (204; 221; 264).
