  • Page 3: System Overview

    1. System overview A complete M-Sens 2 unit consists of the following components: Flange (mounting in screw, hopper) • 1 to 3 sensors with 2 m connecting cable • Transmitter MME 300 for 2 to 3 sensors in a fi eld housing •...
  • Page 4: Function

    2. Function The M-Sens 2 sensor functionality is based on precise high-frequency measurement and direct digitalization of measured values, where from results a high resolution. As the material surface and capillary moisture influences strongly its specific conductive capacity, the moisture can be measured exactly by a constant averaged bulk density.

  • Page 7 APPLICATIONS - PRACTICAL EXAMPLES Installation in a screw • The installation of a moisture sensor in screw feeders proved to be very advantageous, since the material passes by the sensor window in even intervals and with relatively constant bulk density. 13,1 Moisture Screw feeder...
  • Page 8 Installation in a bin • Another installation alternative is to mount a sensor at a bins outlet. Due to constant bulk density in case of a filled bin, the sensor finds an almost unchanging measuring field for monitoring the residual moisture.
  • Page 9 Moisture measurement in a mixer • M-Sens 2 can be installed, even later on, in all types of mixers. The measuring values logging is done by within the moving material during the mixer procedure. With the measured moisture value of the material in the dryer process parameters like detention time and dosage quantity can be controlled.
