Product Overview
The ESF electrical Fire Monitoring Module uses proprietary software algorithm patented technology to accurately monitor and predict temperature and residual current in electrical systems. When electrical equipment residual current, temperature and other data indicators become abnormal, sensors collect indicator changes through electromagnetic induction principles and temperature change effects, izationInformation,transmitstosignalNo.Processingunit.
After intelligent analysis including filtering, amplification, A/D conversion, analysis, judgment, and comparison, real-time data is transmitted to the electrical fire monitoring system. High-speed chips capture key parameters accurately, fast, and stably, enabling early prediction while removing unnecessary parameters to focus on core safety indicators.
