The EGE Elektronik LN 450 GA-S is the authoritative choice for engineers who require quantitative airflow data within tight installation footprints.
The EGE Elektronik LN 450 GA-S is the authoritative choice for engineers who require quantitative airflow data within tight installation footprints. The “GA” designation identifies this sensor as an analog transmitter, providing a continuous 4-20 mA signal proportional to the airflow velocity. This functionality allows for seamless integration into PLCs for Variable Frequency Drive (VFD) control, trend logging, and energy-efficient ventilation management.
