1. Description

Displacement sensor inside a 3B NETlog

sor box and featuring a built-in precision potenti-

ometer 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 without putting too much

strain on the precision potentiometer when it

reaches the limits of rotation.

The displacement sensor is detected automati-

cally by the 3B NETlog

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

the displacement sensor to one of the ana-

log inputs, A or B, on the 3B NETlog



Wait for the unit to automatically detect the

sensor (it will then display "S / U", meaning

"displacement per volt").
