Scale-Tron RadarTron 2250D
Download Specifications

The RadarTron 2250D accurately measures the moisture of fine aggregates such as sand and crushed stone. Its microwave technology eliminates all errors associated with resistance and capacitance methods, guaranteeing an accurate reading every time. RadarTron 2250D adds digital technology to make it even easier to calibrate than before, as well as adding several important new features. It is easily installed in any bin wall and is suitable for digital display as well as direct connection to almost all batching controllers.

There is no mystery in obtaining accurate moisture measurements. The RadarTron sensor is designed to ensure control of the following factors:

• Material Compaction
  No moisture sensor can give you accurate readings unless the material is compacted uniformly when the reading is taken. RadarTron's sensing head packs the material precisely during the flow period.
   
• Material Flow
  Unless the whole sensing element is in the material flow region, which extends vertically above the discharge gate, readings will be affected by the static material in the bin sides. RadarTron adjusts to accomodate all bin shapes.
   
• Averaging Over The Feed Period
  Sensors measure only a few cubic inches of material. As the material flows, the sensor will detect wetter and dryer regions. RadarTron averages these variations to obtain the best readings on every batch.
   
• Material Temperature
  Some sensing methods are very sensitive to the material temperature and must be compensated to obtain even moderately accurate results. RadarTron 2250D's measurement method is not sensitive to temperature. The slight remaining variation in the dielectric constant of the water being measured is compensated by an internal temperature sensor to give the highest accuracy of any sensor available.

The RadarTron 2250D sensor guarantees: consistent yield; consistent colour/texture; consistent workability; consistent strength and durability.
