A versatile sensor for measuring circular motion and oscillations. Combined with EasySense software it makes an ideal demonstration to explain wave phases in SHM and why circular motion can be described as a sine waveform.
This bi-directional 8 range sensor is ideal for Physics departments. Its three-tier low friction pulley is capable of measuring a variety of motions including pendulum, angular and linear.
On the front of the Sensor is a three-tier pulley with 49mm, 31mm and 1mm diameters.
The Rotary Motion Sensor is supplied with a mounting rod that can be attached to four sides of the sensor and then clamped into a suitable holding device in many different orientations. It has a reset button that sets the output of the Sensor to centre point of the scale.
The optional Rotary Motion Accessory kit widens the range of investigations this sensor can achieve as listed below.
The Rotary Motion Sensor can be used to investigate a number of scientific experiments such as:

When the optical encoder disc fitted to the shaft of the sensor turns it cuts through a light source and produce a pulse each time the beam is interrupted. The optical encoder will give a maximum of 1024 counts per revolution of the sensors shaft.
