The accuracy depends on the elevator speed, the type of crop and the moisture of the grain. Mass flow sensor. Yield and moisture data are collected simultaneously to obtain corrected yield. Moisture sensors are often located in the clean grain elevator or the clean grain auger. Moisture sensor installation.
Grain passing over the moisture sensing plate can leave deposits that can affect moisture readings.
Manual measurements should be taken periodically to check the performance of the moisture sensor, especially when operating in severe conditions that can coat the sensor with soil or plant sap. High moisture readings from a dirty sensor will underestimate yield. The console is also used to enter field names, grain type, calibration numbers, correction factors and other user-specified data. Yield monitor console. Electronic flags are often used to record the location of weeds known to be highly correlated with yield reductions.
