PMSA At-line moisture analyser for determination of water content of single paper sheets


At-line moisture analyser with PC software for determination of water content of single paper sheets
The PMSA is a laboratory instrument for the determination of absolute water content of single paper sheets. Contrary to the traditional kiln-drying method,  the PMSA paper moisture analyser determines the water content within a few seconds. The PMSA can be used for analysing samples taken directly from the paper machine as well as for the incoming and exit control of paper sheets.

The analysis of the measuring results is effected on the PC – the intuitive software provides a user-friendly interface for the  display of measuring values, calibration of further paper types and the management of measuring data. The state-of-the-art and long-term stable sensor technology guarantees precise measuring values and extremely high repeat accuracy. To ensure a maximum of accuracy, the system performs a self-calibration of the sensor before each measurement.

Measuring procedure / handling

After installing the PMSA software on your PC, connect the PMSA moisture sensor to the PC via USB cable. Select the paper type to measure in the software and click the start button. To ensure a maximum of accuracy, the system performs a self-calibration of the sensor before each measurement – this only takes several seconds.
When the self-calibration is completed, insert the paper sheet to measure. After a few seconds the determined water content is shown on the screen.
Now additional data like a batch number can be added and the measuring values can be saved in a database. The measuring data can also be exported (csv, html, xls) or printed out. Via the software, further paper types can be created and calibrated easily.
