Sartorius designed the PMD300 moisture analyzer series especially for online analysis. These machines provide the user with a complete overview of the current state of a production process or the state of a batch. Thanks to the use of microwave resonance technology, the user continuously receives the moisture content of his material within less than 1 s. Using this information, he can immediately adjust his process to the measurement results. The analysis is independent of matrix properties like product colour or density. As a result, different batches can be analysed without recalibrating. The PMD300 series averages the individual measurements over a user-defined period and then sends them to a PC, switch cabinet or PLC controller. Depending on the type of sensor, the measurable range lies between 0.1 % and 60 % moisture content. Due to the sensors’ compact form and high protection rating, they can be used in the food, chemical or pharmaceutical industry. The ultrasensitive planar sensors, featuring a special ceramic surface, are especially suited for use on conveyor belts or in hoppers. Bypass sensors, which can measure both density and moisture content, are especially suited for pourable or granulated products that are transported through pipes.
