rotation angle sensor for an electrical steering of a flurfu00f6rderzeugs

摘要

An automatic guided vehicle angle sensor has magnetic field sensors (1, 2) orthogonally arranged around a magnet on the shaft axis and processes (10) ideal geometry dependent output signals for comparison with measured values to produce a warning or stop signal if the difference exceeds a set value. Independent claims are included for voltage sensors (26, 28) provided to monitor the magnetic sensor supply voltages.
