When combined with basic electronic circuitry, the sensor detects the change in presence or proximity of ferrous objects. With more complex circuitry and the addition of software and specific mechanical hardware, a VR sensor can also provide measurements of linear velocity, angular velocity, position, and torque. A VR sensor used as a simple proximity ensor PDF can determine the position of a mechanical link in a piece of industrial equipment.

Dieses Buch führt Sie in eine dunkle und höchst eigenwillige Nische der Kunstgeschichte. Es präsentiert das Werk des belgischen Sonderlings James Ensor und spürt seinem einzigartigen Repertoire an makabren Szenerien voller Galgenhumor nach.

This sensor consists of a permanent magnet, a ferromagnetic pole piece, and coil of wire. VR sensor interface circuits VR sensors need waveform shaping for their output to be digitally readable. The normal output of a VR sensor is an analog signal, shaped much like a sine wave. The frequency and amplitude of the analog signal is proportional to the target’s velocity. This waveform needs to be squared up, and flattened off by a comparator like electronic chip to be digitally readable.

To measure angular position or rotational speed of a shaft, a toothed ring made of ferrous material can be attached to the shaft. When the gear tooth is close to the sensor, the flux is at a maximum. When the tooth is further away, the flux drops off. Although VR sensors are based on very mature technology, they still offer several significant advantages. The first is low cost – coils of wire and magnets are relatively inexpensive. Unfortunately, the low cost of the transducer is partially offset by the cost of the additional signal-processing circuitry needed to recover a useful signal.
