摘要： An electrostatic encoder (40) detects the rotation angle of a rotor (42) with great accuracy based on the change in the capacitance between electrodes arranged on a stator (41) and the rotor (42). Detection electrodes (44a to 44d) and transmission electrodes (45a to 45d) are arranged circumferentially and alternately on the stator (41). Detection signals (phase A, phase B) amplitude-modulated based on the rotation of the rotor (42) and having a mutual phase difference of 90 degrees are output from adjacent ones of the detection electrodes. Modulated signals (V1, V2) are generated by demodulating the detection signals having a mutual phase difference of 90 degrees. Applying resolver-digital (RD) conversion processing to the modulated signals allows obtaining the rotation angle of the rotor.

摘要： A meteorological system for calibrating a field measurement apparatus includes a field measurement apparatus coupled to a field device. The measurement apparatus is configured to generate measurement signals corresponding to a physical measurement associated with the field device. The measurement signals define a raw data stream. The system also includes a mobile calibration device including a transfer function module with a resident corrective algorithm. The mobile calibration device also includes a calibration standard data module including calibration standard data associated with the measurement apparatus resident thereon. The mobile calibration device is configured to establish bi-directional communication with the measurement apparatus, facilitate shifting the measurement apparatus to a calibration mode, receive the raw data stream from the measurement apparatus, transmit the raw data stream to the transfer function module, and calibrate the field measurement apparatus. The transfer function module is configured to generate a difference data stream through the corrective algorithm.

摘要： The invention relates to a device (1) for measuring a rotor parameter, comprising: an incremental material measure (11), which is connected to a rotor or stator in a rotationally fixed manner and which has increment marks (12), an increment-measure sensor (15), which is arranged facing the incremental material measure and which is arranged on the stator if the incremental material measure is connected to the rotor in a rotationally fixed manner and which is arranged on the rotor if the incremental material measure is connected to the stator in a rotationally fixed manner, and an evaluating unit (30). The device has a timer (40), which is reset and restarted each time an increment mark passes by the increment-measure sensor. In dependence on a value of the timer, the evaluating unit determines the rotor parameter for an intermediate rotational position of the rotor lying between two rotational positions of the rotor that correspond to two adjacent increment marks (12.1, 12.2) that the rotor passes by in succession. The invention further relates to a method for measuring a rotor parameter and to a method for reducing rotational differences of a rotor.
