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
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
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
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
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
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
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
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
