1	RADARTRON by SCALE-TRON
2	WHY DO WE NEED MOISTURE MEASUREMENT? Wet cast – measurement in sand corrects both sand weight and water Dry cast – measurement in sand corrects sand weight only – additional measurement required in mixer Benefits in product: Consistent slump Consistent workability Consistent color/ texture Consistent maximum strength Less wasted batches Less testing labor
3	PRINCIPLE OF OPERATION Dual detector measures reflection distance Peak detection ignores voids when averaging 3 averaging methods – fast, slow, sampling THE 3 ESSENTIALS FOR ACCURACY: Measurement within flow region “Sampling” creates average during flow period Compaction of material gives constant density
4	COMPARISON WITH OTHERS Costs 30% less than Hydronix Hydro Probe-II while equal in performance Linear output – separate box not required Does not require separate power supply One-hole installation is simpler than any other Long enough for all hoppers – no adaptor needed Empty bin detection prevents spoiled batches The only sensor with 5 year wear guarantee Computer software gives 1-step calibration Fast service from Canada, instant engineering help Over 1000 installed, long track record
5	RADARTRON APPLICATIONS All types concrete plant (“star” plant shown) Conveyors and chutes Coal and carbon Mining, metal ores Grain, flour, meal Foundry sands Industrial clays Limitations are with chemically combined water, oil mixtures
6	INSTALLATION TIPS Must be in moving material – not weigh hopper Opposite wall from vibrator, away from heat Vibration and cooling kits available In bin or chute that gives compacted material Conveyors require deep bed of material New materials must be tested and sensor adjusted Not recommended for particles over 0.5 inch Only valid test is to use on-line, observe and measure results, compare performance
7	FUTURE DEVELOPMENTS New sensor will be unveiled at 2004 shows Density independent, giving higher accuracy Will handle many materials Analog and digital outputs Remote calibration Rugged surface-mount microstrip circuit
8	SALES CHANNELS As part of batching control systems for concrete and asphalt, to end users. One company has purchased 24 RadarTrons over 5 years As add-ons to existing and new plants Through batching control suppliers Through plant builders for concrete and asphalt and other OEMs Manufacturers of dryers for grain, chemicals, clays and mined products Moulding and extruding machinery
9	COMING IN 2005 VERSION FOR SUGAR REFINING Installs in evaporation vessels. Capable of operating at up to 200 F (95 C) temperature Also withstands partial vacuum Food quality materials Measures from 60 to over 95 degrees brix with 4 - 20 mA or 0 – 10 volt output
