Moisture analysers of the MM 6000 series consist of a microprocessor-controlled evaluation unit and a planar sensor which are integrated in a housing. The MM 6000 series uses 2-PMR technology with patented reference resonator. The measuring field of the microwave resonator is filled with material. The resulting moisture-dependent change in the natural frequency and half intensity width is measured and evaluated considering the measured values of the reference resonator. The result is the density-independent moisture content of the sample.
Optionally, the measuring system can be expanded to a density analyser. The material moisture and density are then determined simultaneously. The moisture value is represented and stored, if desired. Up to 32 different articles with the belonging calibration curve can be stored in the EPROM memory of the system. The data can be copied to or from a connected PC with a backup function. A password protects all or only individual data levels against unauthorised access.
The system has user programmable analog inputs and outputs, control and alarm lines and a serial or TCPIP interface for the transmission of data to a PC. For the data transmission to higher-ranking process control systems, analog outputs (4 to 20 mA) are available.
