Datum Electronics’ Series 420 PTO (Power Take-Off) drive shaft torque & shaft power monitoring system is designed to monitor and log torque, shaft speed and transmitted power from all standard PTO shafts. This type of efficient measurement and monitoring can be a useful tool in research and analysis related to the performance of a tractor’s transmission system, providing efficiency savings and control.

The PTO shaft power monitoring system has a non-contact transmission system that provides a digital output directly proportional to torque. It is supplied as a complete transducer and features bearings that support the stator unit on the rotating shaft. It is quick & easy to install, highly robust, and performs well in a wide range of mechanical and thermal conditions.
