Abstract

The measuring system is used to sense two temporally variable primary measured variables (x1, x2) and/or a secondary measured variable (y1) derived therefrom. It comprises measurement electronics, an active sensor element (C1), a passive sensor element (R1) and electrical connecting lines. The sensor element (C1) generates a voltage dependent on x1, while the sensor element (R1) changes its resistance depending on x2. For a defined interval (t1), the measurement electronics drive a measurement current through R1 and interrupt this before (t2) and after (t3) this interval, with the result that rising and falling current flanks arise in the transitional intervals (t-4, t5). Moreover, the measurement electronics temporarily sense and analyse the voltages (u1, u2) and implement this measurement in particular time intervals in order to allow failure-free and precise evaluation.
