Why Choose the Rittal CMC III Analog Airflow Sensor DK7030.140?
The Rittal CMC III Analog Airflow Sensor DK7030.140 is a compact and reliable analogue airflow monitoring sensor designed for continuous monitoring of airflow conditions in IT racks, industrial enclosures and facility management applications. As part of the advanced Rittal CMC III monitoring system, it provides accurate airflow measurement and helps identify changes in cooling performance, ventilation and filter condition.
This sensor connects directly to the CMC III Processing Unit through a CAN bus interface, allowing automatic detection and simple plug-and-play integration. Its external airflow probe measures air movement within the enclosure, enabling operators to monitor airflow trends and configure warning and alarm limits through the CMC III system.
With a compact enclosure measuring 110 × 30 × 40 mm and a robust IP20 housing, the Rittal DK7030.140 is ideal for monitoring cooling systems, fans, filters and climate control equipment where reliable airflow supervision is required.
