摘要： The invention relates to a NDIR-gas analyser comprising an infrared radiation source (1), a measuring vessel (3) containing a gas mixture (4) having a measuring gas component (5) that is to be detected, and a detector device (7) that is arranged behind the measuring vessel that can detect the influence of ageing of the radiation source (1) and optionally dirt deposits in the optical radiation path without interrupting measuring. According to the invention, at least one optopneumatic detector (15) is arranged in the beam path of the radiation source (1), said detector being filled with any gas (16) when arranged between the radiation source (1) and the measuring vessel (3). The concentration of measuring gas components is lower in the detector (15) than in the measuring vessel (3) if filled with the measuring gas components, and said detector is filled with a gas when arranged between the measuring vessel (3) and the detector device (7), the absorption spectrum of the detector being outside of the spectrum of the measuring gas components (5) and other transversal gases in the gas mixture (4). The measuring signal (12) of the detector device (7) is corrected by the detector signal (21) generated by the detector (15).

摘要： The invention relates to a NDIR two beam gas analyser in which infrared radiation is guided by modulation in an alternating manner through a measuring chamber and a reference chamber and is subsequently detected, a measurement signal being produced due to the analysis which determines the concentration of a measurement gas component present in the measurement chamber. The detection and compensation of error effects, in particular modifications on the infrared radiation source or detector arrangement, is simplified as a phase imbalance is produced in the switching of the radiation between the chambers, and the measurement signal is detected in a phase-sensitive manner for modulating the radiation, a measurement signal vector (SF) comprising amplitude information and phase information (ΦF) is obtained such that during calibration of the gas analyser for different known concentrations (K1, K2, K3, K4, K5) of the measurement gas components, measurement signal vectors (S1, S2, S3, S4, S5) having different amplitudes and phases are determined, vectors define a characteristic line (43), and when an unknown concentration of the gas component is measured, the unknown concentration of the measurement gas component is determined from the intersection point (45) of an obtained measurement signal vector (SF) or the extension thereof with the characteristic line (43).

摘要： A measurement method in which, at the start of a measurement chain, a measured variable is picked up and is further-processed over the course of the measurement chain by conversion to generate a measurement result, where the original or converted measured variable is modulated at a predetermined modulation frequency at a first point in the measurement chain. At a second point in the measurement chain or sequence, which is after the first point in the direction of further-processing, a variable is added to the converted measured variable. The measurement chain or sequence is calibrated using different known values for the measured variable, where different vectors are obtained that define a characteristic, and an unknown value for the measured variable is determined from that point of the characteristic at which the vector obtained in the process or its extension intersects the characteristic.

摘要： A detector arrangement for detection of a measuring gas component in a gas mixture is provided. The arrangement includes a gas analyzer, a first single-layer receiver and a further single-layer receiver, the first single-layer receiver containing the measuring gas component and the further single-layer receiver containing a transverse gas. A concentration of the measuring gas component in the gas mixture is determined from signals delivered by sensors of the single-layer receivers. An evaluating device includes an n-dimensional calibration matrix for obtaining matrix signal values. Signal values of different known concentrations of the measuring gas component in the presence of different known transverse gas concentrations are stored as n-tubules in the evaluating device. The concentration of the measuring gas component in the presence of unknown transverse gas concentrations is determined by comparing n-tuples of signal values thereby obtained with the n-tuples of signal values stored in the calibration matrix.
