An Extended Octagonal Ring Transducer for the Compression Chamber of a Large Square Baler

An extended octagonal ring (EOR) transducer was designed and developed to measure forces inside the compression chamber of a large square baler in different directions. The transducer was calibrated by applying forces in three directions simultaneously and independently. The sensor revealed excellent linearity along with small cross sensitivities. Horizontal and vertical primary sensitivities of the sensor were ۱,۴۷۹.۷ and ۱۳۸۷.۸ μVkN-۱V-۱, while horizontal and vertical cross sensitivities were ۰.۶۴ and ۲.۸۵% of the sensor primary sensitivities, respectively. The sensor was used to measure the forces inside the compression chamber of a large square baler in different directions.
