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 1,8 m connecting cable • Evaluation unit MME 100 resp. MME 300 in a field 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, wherefrom results a high resolution. As the materials sur- face and capillary moisture influences strongly its specific conductive capacity, the moisture can be measured exactly by a constant averaged bulk density. -
Page 5: Safety
The measuring system must be installed by trained and authorised personnel only. Switch off the supply voltage for all maintenance, cleaning or inspection works on the tubes or on components of the M-Sens 2. Follow the notes of the chapter "mainte- nance". ... -

3.4 Technical progress SWR reserves the right to adapt technical data to the technical progress without particular advance notice. If you have any questions, SWR engineering will be pleased to inform you on possible changes and extensions of the operating instructions. - 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. •...
- Page 8 Thus, M-Sens 2 avoids that too damp material reaches the next pro- duction level or arrives into the loading.
- 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 deten- tion time and dosage quantity can be controlled.

4.4 Mounting of the evaluation unit The whole electronic equipment can be installed at a maximum distance of 300m from the sensor. The housing is prepared for wall mounting Fig. 10: Field housing for the evaluation unit Fig. 11: Field housing for the C-box The C-box contains fuses and resistances in order to guarantee the communication by the Mod-bus between sensor and evaluation unit. -

Page 12: Commissioning
6. Commissioning AT the first commissioning of the M-Sens 2 it is necessary to calibrate the sensor. Please consider: Correct connection between sensor, C-box and evaluation unit 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 con- tact SWR. - Page 13 Analogue outputs The analogue outputs can be defined in menu point 5. They can be adapted to the operator’s requirements (e.g. 0-20mA). Basic points The measurement can be checked for linearity by means of varying moisture values. To improve the accuracy those values have to be determined.

Page 25: Wiring Example
In case of a defect during the warranty period, defective components are repaired or are re- placed free of charge. Replaced parts turn into the property of SWR. If desired by the cus- tomer that the parts should be repaired or replaced in its factory, then the customer has to take over the costs for the SWR-service staff. -
