RX30 Inline Grain Moisture Meter

Inline Moisture Monitoring for Corn, Soybean, and Grain

The RX30 brings continuous moisture measurement into the grain flow for facilities handling large grains. Its single-kernel sensor installs inline, inside an elevator or bucket, and measures moisture as grain passes through, covering corn and soybean as well as barley, wheat, and rice. Operators see live moisture on a touch-panel controller and can act the moment readings drift, with no need to stop and pull samples. The system scales from a single measurement point to a full facility network.

Solving Real Process Challenges

• Spot checks miss what happens between samples: The RX30 reads continuously at roughly 60 kernels per minute, so you see moisture trends as they develop, not after the fact.
• One reading does not show consistency: Histogram and standard deviation reporting reveal how uniform your grain actually is, not just an average.
• Problems get caught too late: Set minimum and maximum moisture thresholds with siren alarms, so out-of-spec grain triggers an alert in real time.
• Multiple points mean multiple blind spots: Connect up to ten sensors to one system and monitor intake, drying, and distribution together.

Built for Plant Integration

The RX30 uses a Kett single-kernel electrical resistance sensor designed for larger grains, with calibration curves developed by Kett for corn, soybean, and a full range of cereal and rice grains. Readings flow to a touch-panel controller and to PC software that consolidates data across every connected sensor, generates PDF reports, and integrates with external databases. Cable runs reach up to 500 meters, so sensors can sit where the grain is while the controller stays accessible. Optional cloud storage adds remote monitoring and long-term comparison. The system includes five years of data updates and is backed by the One Year Kett Total Care Warranty, covering parts, labor, and specification compliance.

Measuring only rice, paddy, or wheat? The RX20 Inline Grain Moisture Meter offers the same inline system tuned for smaller grains.

Need a simpler single-point monitor without PC integration? The PT2700 Inline Grain Moisture Monitor mounts on a dryer and reads moisture on its own display, no computer required.
