EST Temperature Monitoring Module
8/100-Channel Temperature Monitoring, Patented Algorithm + High-Precision Sensors, Making Data "Reliable" and "Smart-Controllable"
By monitoring hotspot temperatures such as switch contacts in real time, it detects early signs of abnormal heating to prevent failures. Temperature sensing relies not only on sensors but also on the module's temperature acquisition, analysis, and trend judgment, integrating "measure, control, transmit, and intelligize" in one unit.
Product Overview
The EST Multi-Channel Temperature Module uses proprietary software algorithm patented technology and embedded programs, matched with industrial-grade measurement and control chips, to accurately achieve data processing and predictive analysis. By Real-Time monitoring of switch contacts and other hotspot temperatures, it can detect abnormal heating failure signs, thereby preventing failures, and through temperature history records, provides scientific data basis for "condition-based maintenance" of switch cabinets.
Temperature sensing relies not only on sensors but also on the module's temperature acquisition, analysis, and trend judgment, making data "reliable" and "smart-controllable".
