1. Description
Displacement sensor inside a sensor box and fea-
turing a built-in precision potentiometer plus a ro-
tating pulley onto which a string can be wound in
order to measure displacement. Suitable for re-
cording periodic and oscillatory movements which
can be traced by the turning of the string on the
pulley without putting too much strain on the preci-
sion potentiometer when it reaches the limits of ro-
tation.
Automatic sensor recognition through CMA inter-
faces distributed by 3B.
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 interface or connect it to the com-
puter and start the Coach software. Connect
the displacement sensor with the sensor ca-
ble to one of the analog inputs of the inter-
face.
Wait for the unit to automatically detect the
sensor
