Datasheet EE671 HVAC Air Velocity Probe

EE671 HVAC Air Velocity Probe The compact EE671 air velocity probe is dedicated for HVAC (Heating, Ventilation, Air Conditioning) applications. It operates on the hot-film anemometer principle and offers high accuracy and excellent long-term stability. Reliability The flow sensing element combines state-of-the-art E+E thin-film technology with modern transfer molding technology. By this, the EE671 is very robust and highly insensitive to contamination. Easy installation EE671 is available with M12 connector. The alignment strip on the probe facilitates the correct positioning in the air...
