Sensor, has converter to generate electrical signal and signal processing unit to generate output signal with switch unit for offset compensation and devices for frequency-dependent mode switching

摘要

The sensor has a converter (1,2) to produce an electrical signal and a signal processing unit (3-29) to generate an output signal. The signal processing unit has at least one switch unit (5) for offset compensation and devices (8-27) for frequency-dependent operation mode switching. The switch unit is operated with low frequencies in switched operation mode and with high frequencies in continuous operation mode.
