摘要：A measuring apparatus has a sensor element that produces an output signalproportional to a variable to be measured. An integrator which, beginning at a starting

value, integrates the output signal from the sensor element. A comparator is connecteddownstream of the integrator, compares the output signal from the integrator with athreshold value, and outputs an output signal corresponding to the result of the

comparison. A reset device that is likewise connected downstream of the comparator andresets the integrator to the starting value at specific times. This is a simple way ofachieving integrability in autonomous modules.
