Working Principle
Two fully independent parallel analog signal conditioning and digital processing subsystems simultaneously compute vibration, temperature and rotational speed metrics from field sensor inputs; internal cross-voting logic validates matching measurement results before threshold comparison; dual redundant safety relay circuits execute machinery shutdown interlock only after synchronized validation from both processing cores; measurement data transmits over isolated dual Ethernet communication paths to plant safety control systems.
