Which sensor is used to measure the rotational speed of an element in yield monitoring?

The shaft speed sensor is essential in yield monitoring systems as it provides accurate measurements of the rotational speed of various components, such as the harvesting equipment's augers or the drive shafts. This data is crucial because it allows for the calculation of yield rates by correlating the speed of the equipment with the amount of material harvested. This sensor typically employs methods such as magnetic or optical sensing to detect how fast the shaft is turning, enabling the system to adjust yield calculations in real-time based on the operational conditions. Therefore, the shaft speed sensor plays a central role in ensuring that yield data is precise and actionable, which is crucial for farm management and optimizing production efficiency.
