MIIGO - EE671 Compact Air Velocity Sensor – High-Precision HVAC & Process Monitoring

DESCRIPTION

The EE671 Air Velocity Sensor operates on the hot-film anemometer principle, ensuring high accuracy, reproducibility, and long-term stability. Designed for HVAC, industrial flow monitoring, and inlet air measurement, it provides air velocity readings up to 20 m/s (4000 ft/min). The device is available with a fixed cable or plug connection, supporting analog (0-1V, 0-5V, 0-10V) and Modbus RTU outputs. Its alignment nut and mounting flange simplify installation, ensuring precise airflow measurement.
