A device was developed to evaluate the energy consumption in the vertical vibratory tillage of the induced type, to determine the energy consumption required to achieve the plowing of the soil. The equipment is made up of an octagonal extended ring transducer (OAE), a supporting structure, an oscillating mechanism, a floor rotating chisel and a hydraulic system for the drive. The present work considers, the calibration in laboratory of the sensors of the octagonal of extended ring that allows to measure the horizontal force and vertical force during the plowing of the ground, the sensor to measure the frequency of the vibratory rudder and the torque sensor that allows measuring the torque consumed by the oscillating mechanism for breaking the ground. The transducer calibration results (OAE) for the vertical force had a calibration constant of 75.00 N mV-1 with a linearity of 99.8%, for the horizontal force a constant of 47.74 N mV-1 with a linearity of 99.7% and for the torque transducer a constant of 0.4538 Nm mV-1 with a linearity of 98.8%, guaranteeing high reliability and precision of the measurements of forces and torque.
