Design and Research of an Ultrasonic Grain Moisture Content Detection Device

In view of the current traditional grain moisture detection equipment is greatly affected by the environmental temperature and has long detection cycle, small detection range and other problems, this paper uses ultrasonic sensor technology, combined with automatic control principle, to study the current grain moisture detection problems. A kind of detection device for grain moisture detection by ultrasonic wave is designed. Compared with the traditional laboratory grain moisture detection, the detection device can feed back the transmission status of ultrasonic wave in the detection sample through the sensor in real time, and get the detection results in a short time. Compared with the traditional capacitive resistance grain moisture detection device, the ultrasonic grain moisture detection device is less affected by the environmental temperature and has a larger detection range. The research shows that the widespread use of the ultrasonic grain moisture detection device can effectively increase the grain detection efficiency and improve the measurement accuracy, which is of great significance for controlling the grain quality and ensuring the grain storage security.
