Method offers fail safe variable reluctance sensors:
11/22/2001 EDN - Design Ideas / Variable-reluctance sensors are
preferred for industrial and automotive environments, because
they sustain mechanical vibration and operation to 300 C. In
most applications, they sense a steel target that is part of a
rotating assembly. Because the unprocessed signal amplitude is
proportional to target speed, a sensor whose signal-processing
circuitry is designed for high speed cease... |
