Rotary motion sensor - DT148

This Rotary Motion Sensor measures angular position in very high resolution and counts the sensor pulley turns. It can also be used to measure linear motion with a resolution of 0.1 mm. This is done by rolling the pulley along a plane, or by hanging a string over the pulley.

The Rotary Motion Sensor comes with a 3-step pulley and mounting rod. An optional accessory is also available: a pendulum that consists of a long light aluminum rod and two brass masses which can be attached at any point on the thin rod.

Fourier’s Rotary Motion Sensor is a sensitive, accurate angular and linear position sensor. Common experiments include: acceleration, pendulum, harmonic motion, torque, moments of inertia and for very accurate linear position in two slits laser interference.
