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 •...
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.
If a damage is found, it is to repaired before further operation of the instruments. Technical progress ENVEA - SWR engineering reserves the right to adapt technical data to the technical progress without • particular advance notice. If you have any questions, ENVEA - SWR engineering will be pleased to...
4. Montage and installation 4.1 Delivery parts Transmitter in the field housing • Sensor • Operating instructions • C1-box (optional) • Welding flange • 4.2 Auxiliary Screw driver 2.5 mm • Allen key 5 mm • 4.3 Mounting of the sensor M-Sens 2 is designed for continuous moisture measurement.

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...

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.

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.
4.4 Mounting of the transmitter The whole electronic equipment can be installed at a maximum distance of 300 m from the sensor. The housing is prepared for wall mounting. Fig. 9: Field housing for the transmitter Sensor 1 Transmitter Cable gland M 16 x 1,5 Fig.

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.
