DMMS is especially suitable for challenging applications. Up to 16 sensors are able to communicate digitally with a central evaluation unit. Wiring becomes easy by using bus-technology. That makes it simple to upgrade the measuring points. The bus-system can manage a max. length of 1.200 meter which allows you to cover even spacious estates. The calibration is made on-line within the process, so after the sensor has already been implemented. As a result the influences caused by the assembly situation can be immediately detected and compensated. The kind of measurement can be chosen between constant and batch operation (via start and stop signal). It's also possible to change material (up to 16 different material curves/sensor). The transfer of the measuring values can be done digitally by Profibus DP or by standard signal (e.g. 4…20mA, 0..10V). If the sensor has to be exchanged the calibration curves can be completely adopted -there's no additional effort.
