Measurement system, especially for detecting seat occupancy in motor cars, improved so measurements are little affected by monofrequency or narrowband noise

摘要

The measurement arrangement has at least one sensor (1.1,1.2,1.3) for producing a measurement signal, at least one signal generator (3) connected at its output side to the sensor for stimulating the sensor and at least one evaluation unit (8) for evaluating the sensor signal and forming a reference value. The stimulation signal is a broadband signal so as to suppress the influence of monofrequency or narrowband noise signals.
