Description
The EGE Elektronik LC 521/2 GSP-Ex22 is the authoritative solution for monitoring airflow in large-scale industrial systems where combustible dust hazards are present. Certified to ATEX Category 3D, this sensor is engineered for Zone 22, providing a safe and reliable monitoring point for heavy-duty extraction systems, silos, and pneumatic lines without the need for additional intrinsically safe barriers. The defining feature of the LC 521/2 is its significantly extended probe length. In large-diameter ventilation shafts or heavily insulated piping, standard-length probes often fail to reach the laminar flow zone, leading to inaccurate readings. The double-length probe of the /2 variant ensures the calorimetric sensor tip is positioned perfectly in the air stream. Because it utilizes the thermal (calorimetric) principle, the sensor is completely solid-state—ideal for dusty environments where mechanical vanes or paddles would quickly jam or corrode.
