The Rotary Motion sensor has is a low friction bi-directional position sensor, which can be used to perform a variety of investigations into rotational mechanics. It contains an optical encoder, which gives a maximum of 1 024 counters per revolution of the sensor’s shaft.
This sensor can be used to measure directly:
- Linear displacement by using any of the pulley ranges or the linear rack accessory.
- Angular displacement using the angular position or pendulum range
- Angular velocity using either the revolutions or radians per second range.
A spoked pulley (3177) can be used with this sensor to convert movement from one angle to another.
