Sensor for Paper Thickness Measurement

[Revathysrini]

Hi all,

Which type of sensor is more accurate for Paper thickness Measurement (75-85 micron).

Thanks,

Hi,

if there is a fixed dielectric constant then i´d use a capacitive sensor.

a mechanical solution can be to push the paper between two ball bearings and measure the distance..

optical: light shine through

it depends on some parameters wich solution to choose.
