Thermal Xpert 25 (ETX25) brings Eaton Exertherm’s proven 24/7 hotspot detection into a single, self-contained gateway—making continuous thermal monitoring simpler, faster, and more accessible than ever before.
With no requirement for BMS, SCADA or EPMS, ETX25 delivers real-time thermal insight straight to a built-in web interface. Just connect, monitor, and act using any standard web browser, from anywhere.
ETX25 is the next evolution of Eaton’s industry-proven alarm relay module - ARM XL, re-engineered to remove integration barriers and simplify deployment across any site.
It aggregates data from Eaton Exertherm’s non-contact infrared and cable temperature sensors and presents live and historical thermal data through an intuitive, embedded web interface—no additional software required.
Conventional thermographic inspections provide isolated temperature readings at a single point in time. Thermal Xpert 25 enables a fundamentally different approach, continuous temperature monitoring, delivering persistent visibility of thermal behaviour across critical electrical connections.
By capturing and trending temperature data 24/7, ETX25 identifies abnormal thermal rise at its earliest stages, supporting proactive maintenance strategies, improved asset reliability, and reduced risk of unplanned failure.
