| EE671 | HVAC Miniature Air Flow Probe |
| EE671 is a compact air velocity probe for HVAC applications. The built-in flow sensing element VTQ combines the advantages of state-of-the-art E+E thin-film manufacturing and of the newest transfer molding technology. | |
| Type | EE671 air velocity sensor cable version |
| EE671 air velocity sensor plug version | |
| Detail | It operates on the hot-film anemometer principle and ensures high accuracy and reproducibility as well as long-term stability and outstanding resistance to pollutants. |
| EE671 is available with fix installed cable or with plug connection. The measured air velocity up to 20 m/s (4000 ft/min) is available at voltage output 0 – 1 V, 0 – 5 V or 0 – 10 V or on the Modbus RTU interface. | |
| The alignment nut on the probe and the matching mounting flange simplify the installation, the correct orientation in the air flow and the precise control of the immersion depth. | |
| With an optional configuration kit the user can set via a digital setup interface the output configuration and perform an adjustment of the probe. | |
| Typical Applications | Heating and ventilation systems |
| Flow monitoring and control | |
| Inlet air monitoring in ovens | |
| Key Features EE671 | High accuracy and long-term stability |
| Outstanding resistance to contamination | |
| Easy and quick mounting | |
| User configurable | |
