The EGE Elektronik LNZ 450 GA-K is the authoritative choice for industrial applications that require more than a simple “flow/no-flow” signal.
The EGE Elektronik LNZ 450 GA-K is the authoritative choice for industrial applications that require more than a simple “flow/no-flow” signal. The “GA” designation indicates a 4-20 mA analog output, which transmits a continuous signal proportional to the airflow velocity. This allows your PLC or Building Management System (BMS) to perform advanced functions such as variable fan speed control, precise trend logging, and predictive maintenance based on declining flow rates.
EGE-Elektronik Spezial-Sensoren GmbH has been developing and manufacturing special purpose sensors for automation applications since 1976. The company serves leading international producers from a wide range of industries. Its product portfolio includes flow controllers, infrared, opto and ultrasonic sensors, capacitive proximity switches, light barriers and inductive proximity switches. EGE also provides sensors for highly sensitive applications, e. g. hazardous areas. The development department`s highly qualified staff cooperates closely with all customers, ensuring continuous product updates and enhancement.
EGE has been a pioneer in the field of flow controller and an innovator and decisive participant in the development of today's globally utilized thermal flow controllers. The in-house EMC and test laboratories ensure that all inspections and tests required for permits and conformity certificates are carried out quickly and reliably. Product quality is guaranteed with a continuously monitored quality management system in accordance with EN ISO 9001:2000.
