Page 3: System Overview
1. System overview A complete M-Sens 2 unit consists of the following components: 1 welding fl ange per sensor • 1 to 3 sensors with 2 m connecting cable • Transmitter MME 300 up to 3 sensors in a DIN rail 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 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.

Page 13: Commissioning
Correct installation of the sensor in respect to the wall thickness. • In case of negative results in spite of consideration of the points as stated above, please contact SWR. Commissioning of the M-Sens 2 After the delivery the sensor is not calibrated to the product(s), so each calibration and parameterization has to be executed during the commissioning. - Page 14 Analog output is modified in menu 5 and can be adjusted to user requirements here (e. g. 0… 20 mA). The calibration of the starting value takes place in menu items 5.7 and 5.8. Standard MIN = 4 mA MAX = 20 mA The measuring range filter makes it possible to adapt to slower recording devices or continuous output at the analogue output (power output).
