An Extended Octagonal Ring Transducer For the Compression Chamber of A Large Square Baler

An extended octagonal ring (eor) transducer was designed and developed tomeasure forces inside the compression chamber of a large square baler in differentdirections. the transducer was calibrated by applying forces in three directionssimultaneously and independently. the sensor revealed excellent linearity along withsmall cross sensitivities. horizontal and vertical primary sensitivities of the sensor were1,479.7 and 1387.8 ىvkn-1v-1, while horizontal and vertical cross sensitivities were 0.64and 2.85% of the sensor primary sensitivities, respectively. the sensor was used tomeasure the forces inside the compression chamber of a large square baler in differentdirections.
