MOISTURESONO-VARIOSONO-VARIO SPECWATER/MOISTUREVIDEO/BROCHURE
The SONO-VARIO moisture level sensor uses Time Domain Reflectometry to measure the moisture of the material.
The SONO-VARIO moisture level sensor uses Time Domain Reflectometry to measure the moisture of the material.

Measuring range: 0 – 20% moisture, precalibrated for sand. Other ranges and materials on request.Can be calibrated for surface or total moisture, “wet” or “dry” calculation basis.
Material limits: From powder to 1.25″ (32 mm) aggregates and accuracy within 0.2% over this range.
Sensing volume: Measuring depth of approximately 1 ” – 2 ” (30 – 50 mm).
Analog output 1: 0-20mA, 4-20mA, Moisture reading.
Analog output 2: Temperature (0-70°C, 32-158°F), conductivity or standard deviation of moisture readings.
Digital RS485 connection: Bidirectional, industry standard protocol and command structure supports multiple moisture probes on the same RS485 multi-drop line.
IMP-Bus Isolated proprietary current bus solves many RS485 problems.
Power: 12 – 24 VDC, 3 W max.
Measuring cycles: From fast response with no filtering to averaging or Kalman filtering.  6 modes available.
Calibration curve storage: Up to 15 sets of calibration curves can be stored internally and called from the RS485 or IMP-Bus  interface.
Ambient temperature:  Sensor body temperature for full accuracy: 0-70°C (32-158°F).  
Construction: Stainless steel body and flange with extra hard alumina ceramic faceplate, 3 mm thickness.
Size: 4-1/4″ (108mm) diameter, 1.8″ (45mm) long with angled flange for correct positioning of faceplate under aggregate gate.
Guarantee: 1 year guarantee on material and workmanship; return for replacement.
