The information coming from the diagnostic system is of vital importance for the correct functioning of many electromagnetic devices. In particular, for nuclear fusion devices, the magnetic measurements are used for a number of fundamental identification tasks such as equilibrium analysis and plasma boundary reconstruction. The quality and the reliability of the measurements strongly impact the final results; therefore, proper techniques able to detect faulty probes and to assess their effectiveness are very beneficial. When calibration and other self-consistency tools fail to detect loss of reliability, numerical approaches can help in detecting and eventually correcting information from the malfunctioning channels. This paper proposes a general approach for the fast identification of broken probes based on suitable reconstruction procedures. The approach is tested in Tokamak reactors, but it is quite general and it can be easily extended to other application fields.
