EGE Elektronik Sensor Air Flow Sensors Productseries LN 450 GA-K

The EGE Elektronik LN 450 GA-K is the authoritative choice for engineers who require quantitative data from their ventilation systems but are limited by installation space.

Description

The EGE Elektronik LN 450 GA-K is the authoritative choice for engineers who require quantitative data from their ventilation systems but are limited by installation space. The “GA” designation signifies that this sensor is an analog transmitter, converting detected air velocity into a standardized 4-20 mA signal. This allows for sophisticated integration into PLCs for variable fan speed control, energy efficiency auditing, and precise environmental monitoring.

Features

  • Analog Output (4-20 mA): Delivers continuous data for real-time monitoring and advanced process automation.

  • 24V DC Operation: Optimized for standard industrial power supplies and control architectures.

  • Space-Saving Design: A smaller footprint than the LNZ series, making it ideal for electronic cabinets and small ducts.

Applications

  • Variable Fan Control: Providing feedback to VFDs to maintain constant airflow in small-bore cooling systems.

  • Cleanroom Monitoring: Continuous velocity tracking in specialized pharmaceutical or medical workstations.

  • Cabinet Thermal Management: Precise monitoring of airflow in high-density server or control racks.
