A baler with automatic sensor calibration

摘要

A baler (10) comprises a baling chamber (24) and a sensor arrangement. The sensor arrangement comprises at least one sensor (34) arranged to provide information about a mechanical property of a bale (32) built in the baling chamber (24) and a control unit (50) receiving signals from the sensor (34). The control unit (50) is operable to automatically calibrate the signals from the sensor (34) based upon at least one signal from the sensor (34) received in at least one known state of the sensor (34).
