摘要： A potentiometric sensor for measuring a potentiometric variable of a medium comprises an ISFET whose gate region exhibits an ion-sensitive surface which can be exposed to the medium and which outputs an output signal that depends on the concentration of the ions at the ion-sensitive surface of the gate region. An evaluation circuit with a measuring input to which the output signal of the ISFET is applied is included, whereby the evaluation circuit is designed to output a measured value for the potentiometric variable, depending on the output signal. Also included is a measuring resistor which is arranged between the output of the ISFET and the input of the evaluation circuit, a monitoring circuit to determine the voltage drop over the measuring resistor, and a bridge section that is parallel to the measuring resistor to bridge the measuring resistor whereby the bridge section exhibits a switch with which the bridge section can be opened or closed.

摘要： A method for monitoring sensor function comprises the following steps: repeatedly acquiring data records comprising sensor-specific calibration data; storing the acquired data records comprising sensor-specific calibration data; analyzing changes of the calibration data over time using the stored data records; and determining time or time weighted with a load factor until the next calibration is due, using at least the changes of the calibration data over time. The resulting time or the determined time weighted with a load factor can, for example, be output in suitable form directly after determination, thereby allowing for a long-term planning of calibration, and/or it can be stored as a date or a remaining time. A comparison with a time signal or a count-down of the remaining time allows at the due date to output a request, or prompt, signal, optionally with a desired lead time.
