Monitoring method for sensor, e.g. inductive sensors used in car control systems
摘要
<p>The appliance monitors at least one sensor (103) and includes a first switching circuit (303) for connecting one terminal of the sensor to a power supply and an evaluator circuit (201) for assessing the resultant signal potential at the sensor terminals. The current supplied to the second sensor terminal is adjusted by operation of a second switchable circuit (304). The evaluator circuit can contain at least a first and a second group of circuits connected to the first or the second sensor terminal and also a microprocessor for processing the signals provided by the two circuit groups or for operating the first switching or the second switch able circuit</p>
