Explosion protection of the non-electrical parts of the equipment based on the sliding monitoring
The current international standards specify the explosion protection of the non-electrical parts of the equipment. A risk of explosion can occur when the drive and the output device of the system are interlocked. The article analyses the potential consequences of such interlock and evaluates the potential ignition sources. Also discussed are the explosion protection solutions based on the rotational speed monitoring in order to identify the signs of sliding, an indicator of occurrence of a dangerous situation. The article covers the commercial modules for implementation of such solutions.
