1. Description
Displacement sensor inside a 3B NETlog
and featuring a built-in precision potentiometer plus
a rotating pulley onto which a string can be wound in
order to measure displacement. Suitable for recording
periodic and oscillatory movements which can be
traced by the turning of the string on the pulley with-
out putting too much strain on the precision potenti-
ometer when it reaches the limits of rotation.
The displacement sensor is detected automatically
TM
by the 3B NETlog
unit.
2. Operation
•
Set up the experiment with the displacement
sensor included.
•
If possible, select a zero point in such a way that
the limits of rotation of the pulley are never
reached.
•
Turn on the 3B NETlog
displacement sensor to one of the analog inputs,
A or B, on the 3B NETlog

•
Wait for the unit to automatically detect the
sensor (it will then display "S / U", meaning "dis-
placement per volt").
