Improve sensor life in high radiation environments

April 29, 2013


Extending the life of sensors in a high radiation environment



Battelle Memorial Institute, the world’s largest nonprofit R&D organization was working with Oak Ridge National Labs on a manipulator to be used in a hot cell. The robotic arm originally utilized a resolver, which is less than ideal in a high radiation environment. So they tapped Betatronix to come up with a solution.

Managed by the U.S. Department of Energy, Oak Ridge National Labs (ORNL) has a distinct interest
in safety and efficiency. But using inductive sensors in a high radiation environment can increase both cost and design complexity. Radioactive fields can induce erroneous signals, significantly reduce operational life, and drive the requirement for expensive shielding to protect the sensor.

Working closely with ORNL and Battelle, the Betatronix team was able to develop a radiation-hardened ceramic feedback component for the robotic arm. Another critical feature of this miniature direct contact component is that it was designed to be remotely replaceable, allowing for extended operations in some of the harshest environments any robotic system might encounter – on earth or in extraterrestrial applications.
