Based on the online moisture measurement system MOCON with microwaves, we have developed a variant for online moisture measurement of waste paper / straw bales when transported by truck.
Description
MOCON-LKW is an online measuring system for determining the moisture in the cargo (paper, straw) of trucks using ultra-low frequency microwaves (925-980 MHz).
The loaded truck drives through the RGI 8406 microwave transmitter and receiver modules located on the left and right of the system.
Since microwaves penetrate the process material completely, the moisture of the load can be determined.
The technology guarantees a high level of measurement accuracy and precision: the color and surface structure of the material, dust and water vapor do not affect the measurement results.
The raw data of the microwave sensor measuring section are processed by the evaluation computer; the measurement result is the percentage moisture in the measured material.

High test accuracy: The repeatability for waste paper is 0.2 to 0.5% (automatic scan installation), for wood chips and straw 1%.
8 data can be measured per second, 128 data can be measured for the entire truck (depending on the speed),
It is easy and convenient to calibrate and operate the software.
Data will be immediately displayed simultaneously and in real time in a histogram and a trend diagram to reflect the moisture measurement.
30 different product qualities (e.g. paper of types 1 and 2, bark and corn stalks) can be saved with the software and 30 linear channel memories can be supported.
A multi-port output, 4-20 mA and Modbus RTU ensure data communication with ERP or PLC systems.
