Angular Speed Measurement Trainer

A proximity sensor uses an electromagnetic field to measure changes in the distance to an object. As a gear moves past the sensor, it measures a variation in distance; close (tooth) and far (notch). The rotation speed can be determined based on the time between these events.

The experimental setup helps to study the angular speed of a rotating wheel using Magnetic pick up Proximity sensor. Also verified by Contact type Digital Tachometer and Non – contact type Digital Tachometer.

The experimental setup consists of the following specifications :

    1. Teeth wheel fitted on a motor shaft.
    2. Motor speed controller.
    3. Magnetic pick up proximity sensor.
    4. Power supply.
    5. Digital Counter.
    6. Contact Type Digital Tachometer.
    7. Non-Contact Type Digital Tachometer.
