A system related apparatus for the calibration of a sensor for moisture measurement on sheet, tape or film materials

摘要

The present invention relates to a system for calibrating a sensor (14) for the measurement of the moisture contents of sheet, tape or film materials, characterized in that the calibration curve is determined on a remote sensor (9), said remote sensor (9) being built exactly in the same way as the on-line sensor (14), which remote sensor (9) is kept in a temperature and humidity-controlled room 6 in order to avoid the use of tightly sealed containers to protect sample (2) from moisture changes caused by temperature and humidity differrences between the surrounding environment and the sample, and in that the calibration curve as obtained on said remote sensor (9) is then applied to the line sensor (14).
