In situ light attenuation and backscattering probes were designed, fabricated, and calibrated for monitoring the dust levels in grain elevators. The calibration was performed both in a dust cloud chamber using mixed grain dust and in an elevator facility with various types of grain. The true dust concentration was determined with an isokinetic sampling probe.
