EGE Elektronik Sensor Air Flow Sensors Productseries LN/LG 500

Description

The EGE Elektronik LN/LG 500 series is the authoritative choice for facilities requiring precise airflow supervision with zero mechanical maintenance. The LN 500 series typically features a compact housing for space-restricted applications, while the LG 500 series often provides extended probe lengths or specialized housing materials for larger ductwork and more aggressive industrial atmospheres. Operating on the calorimetric (thermal) principle, these sensors measure the heat dissipation from the probe tip caused by the moving air stream. Because there are no moving parts (no vanes, paddles, or bearings), the sensors are immune to mechanical fatigue and jamming—common failure modes in dusty, oily, or humid air streams. The 500 series is known for its enhanced temperature stability and rapid response times. Each unit includes a multi-segment LED chain on the housing, providing a real-time visual representation of flow velocity relative to the setpoint. This allows for effortless on-site calibration using the integrated potentiometer.

Features

Solid-State Calorimetric Sensing: No moving parts to wear out, ideal for high-vibration and contaminated environments.
High Sensitivity: Accurately detects air velocities even at low speeds (from 0.5 m/s).
Integrated Evaluation: Self-contained electronics eliminate the need for external amplifiers or controllers.
LED Status Display: Visual “thermometer” display provides immediate feedback on flow status and setpoint alignment.

Applications

Large-Scale HVAC: Monitoring supply and return air in industrial manufacturing plants and warehouses.
Exhaust System Safety: Ensuring that toxic or hot fumes are being actively removed from work areas.
Filter Supervision: Monitoring the air velocity drop across large filter banks to signal maintenance.
