ARRANGEMENT AND METHOD FOR OPERATING A SENSOR, IN PARTICULAR A BRIDGE SENSOR, AND A SENSOR ARRANGEMENT |
| 摘要 |
An arrangement for operating a sensor, in particular a bridge sensor, comprises a sensor input (Vin1, Vin2) for connecting the sensor (Brdg) and a clocked signal generator (Osc), which is coupled to the sensor input (Vin1, Vin2). Furthermore an amplifier (Amp) is provided for detecting sensor signals (Sn, Sn+1), which is connected on the input side to a signal input (IN+, IN−) for connecting the sensor (Brdg), wherein the detection takes place depending on the clock pulse of the signal generator (Osc). A signal processing device (PROC) is connected to an output (AOUT+, AOUT−) of the amplifier (Amp) and is arranged to demodulate the sensor signals (Sn, Sn+1) that follow one another according to the clock pulse. |
