ARRANGEMENT FOR PROCESSING SENSOR SIGNALS |
摘要 |
The arrangement serves to process sensor signals which are furnished by a measuring sensor and by one or more further sensors. The measuring sensor generates a measuring effect which depends on a physical measured quantity to be determined and on physical disturbance quantities and each further sensor generates a measuring effect which depends substantially only on physical disturbance quantities. The arrangement includes a signal processing circuit which receives the measuring effects as input quantities. By analog processing of the sensor signals the signal processing circuit furnishes an output quantity, the ratio of which to a reference quantity in dependence upon the measuring effects forming the input quantities is governed by a transfer function defined in specific manner. The coefficients of the transfer function are adjustable for obtaining the desired transfer behaviour in dependence upon the properties of the measuring sensor, the influence of the disturbance quantities on the measuring effect of the measuring sensor thereby being compensated and errors in the relationship between the measured quantity and the measuring effect of the measuring sensor being corrected.
