2 On Mill Unit (OMU) The OMU record, reduce and tranmit enor data by RF link to the Receive Unit. OMU and enor are mounted directly on the hell, rotating with the mill. The ytem i elf-powered by an integrated pendulum driven generator. No battery i needed. Receive Unit (RU) The RU i implemented a eparate unit to achieve a high flexibility. Thu it may be mounted at a place with optimal receiving quality. Via coaxial cable the ignal i ent to the next component: the Bae Unit. 6 V AC (0.5 W / elf-powered) / 200 ma (powered by BU) tranmitter UHF ISM 866 MHz, 2.4 GHz output 2 V pp / 50 Ohm (RG 58, max. 200 m) 23 kg 0.6 kg 300 mm 80 mm 400 mm 125 mm 230 mm 67 mm operating temperature C F operating temperature C F p.2

3 Bae Unit (BU) The BU i the control center of the SmartFill ytem. It perform all mathematical analyi of tranmitted data and link to the plant PLC. The device mut be mounted in an air-conditioned room. The indutrial PC contained require a cool and dut free environment. Temperature Senor The Temperature Senor meaure either the material temperature directly in the diaphragm or the hell temperature on the mill urface. It conit of the enor (right picture) and the amplifier (left picture). Both item are mounted directly on the mill hell and thu rotate with the mill. The pecial low power amplifier i powered by the OMU. 110 V AC / 60 Hz 230 V AC / 50 Hz 5 V DC / 20 ma (powered by OMU) (160 W) thermocouple j-type ignal 2 V pp / 50 Ohm analogue output (x3) / ma digital output (x4) / max. 100 ma output / 500 ma (for RU) amplifier enor 18 kg 600 mm 400 mm 220 mm 1.3 kg 1.2 kg 130 mm 500 mm 220 mm 570 mm 140 mm 15 mm operating temperature C F operating temperature C F C C F p.3

4 Sound Senor The Sound Senor ene the tructure-borne ound for 1 t, 2 nd and 3 rd chamber independently. For each chamber a enor i mounted directly on the mill hell and thu rotate with the mill. There i no amplifier. Thi enor type i intended for dry grinding procee (e.g. cement, mineral, etc.). It enure a very high preciion in fill level. Mounting plate i glued on the hell. Load Senor The Load Senor meaure the total load of the mill. It conit of the enor (right picture) and the amplifier (left picture). Both item are mounted directly on the mill hell and thu rotate with the mill. The amplifier i powered by the OMU. Thi enor type i predetinated for one chamber mill and grinding of material with widely varying moiture. none 5 V DC / 20 ma (powered by OMU) amplifier enor 0.3 kg 40 mm 40 mm 40 mm 1.3 kg 0.2 kg 130 mm 26 mm 220 mm 60 mm 140 mm 26 mm operating temperature C F operating temperature C F C C F p.4

5 Type Selection Module (optional extenion) The Type Selection Module i placed inide the BU and witche between different calibration for different material type. Active type i coded by four digital ignal, which are et by the plant PLC. Thi module i needed, when the different type are trongly varying in their material compoition. A ubequent intallation on ite i poible. Galvanic Iolation (optional extenion) The Galvanic Iolation i placed inide the BU and provide an electrical eparation for the final fill level and temperature output between the BU and the plant PLC. A ubequent intallation on ite i poible.

6 Getting it together d (Bae Unit) digtal in- & output analogue output load reitor 110 V AC / 60 Hz 230 V AC / 50 Hz ma (elf-powered current loop) 1000 Ohm (Receive Unit) p p ignal 2 V pp / 50 Ohm (RG 58, max. 200 m) I/O The analogue output are ued to ignal the calculated fill level ( % of calibrated range) and the meaured temperature ( C). Therefore, each enor ha got a eparate current loop (4..20 ma). The digital output ignal the operating tatu of the Bae Unit. Eay calibration (Sound and Load Senor) Calibration After intallation a calibration of the ound and load enor i needed. Therefore, the mill ha to be run empty and full. For maximum convenience, SmartFill offer automatic calibration mode which can be tarted and topped by uing the Diplay Unit inide the Bae Unit. The diplayed range i 130 % to enure a ignal if the level exceed 100 % of calibrated range. f f c f c f f c KIMA Echtzeityteme Gütener Straße Jülich GERMANY contact@kimae.de p.6
