FAQ
Battery life is approximately 3 years at 25℃. It is replaceable by opening the sensor cover (model CR2450).
Yes, the AHE100 is designed for medium and high voltage switchgear internal monitoring. Please ensure proper installation.
One ATC600-C coordinator can receive data from up to 240 AHE100 sensors.
The LED flashes each time data is transmitted. You can also check received data on the monitoring system (e.g., ATP007 touchscreen).
Summary
The AHE100 wireless temperature and humidity sensor provides reliable and cost effective monitoring for switchgear and distribution rooms. With dual power options, intelligent reporting, and long range wireless communication, it ensures timely detection of abnormal conditions, reducing maintenance costs and improving equipment safety.
