NEULOG ROTARY MOTION LOGGER SENSOR GUIDE
NeuLog rotary motion logger sensor
NUL-226
The NeuLog rotary motion sensor can be used for any science experiment which
involves rotary motion including angular velocity, angular acceleration and revolutions
per second such as in the fields of Mechanics, Physics, Biomechanics, etc.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using this guide.
Among hundreds of possible experimental subjects that can be studied with the NUL-
226 sensor are: rotary motion studies, angular velocity, angular acceleration, sine
waves, torque, engine studies, and many more.
The rotary motion sensor's measurement units are:
Degrees (°): The standard unit for measuring angles
Radians per second (rad/s): The angular displacement’s rate of change
Radians per second squared (rad/s2): The angular velocity’s rate of change
Revolutions per second (rev/s): The total number of complete revolutions
per second.
Using the rotary motion sensor:
The rotary motion sensor can be set up in your classroom or lab in many different
configurations:
Connecting the revolving head to a conveyor system
Rolling the revolving head along a surface
Spinning the revolving head manually.

Technical background:
The philosophy behind NeuLog’s plug and play technology is based on each sensor’s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (oC, oF, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in software in the logger can be
upgraded for free at any time using the provided firmware update.

NEULOG ROTARY MOTION LOGGER SENSOR GUIDE
The probe shaft is installed in a bearing and has a magnet at its end. A digital sensor
based on The Hall Effect sensor, an analog circuit and a very sophisticated digital
processor are located near the rotating magnet.
The analog and digital circuits analyze the rotating magnetic field and calculate the
angle, rotation speed, acceleration and revolutions, transferring this data to the
sensor's controller, upon its request.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the rotary motion sensor’s body.
After use, gently wipe away any foreign material from the rotary motion sensor.
Store in a box at room temperature out of direct sunlight.
Warranty:
We promise to deliver our sensor free of defects in materials and workmanship. The
warranty is for a period of 3 years from the date of purchase and does not cover
damage of the product caused by improper use, abuse, or incorrect storage. Sensors
with a shelf life such as ion selective probes have a warranty of 1 year. Should you
need to act upon the warranty, please contact your distributor. Your sensor will be
repaired or replaced.
