HVAC用微型風速變送器
EE671（EE575升級版本）系列是專為HVAC應用而設計的一款緊湊型風速變送器。
產品內置VTQ型風速敏感元件,該敏感元件結合了E+E研發的高品質薄膜生產技術和*的塑封工藝的優點。
它使用了新型的熱膜風速工作原理，保證了測量的高精度和重復性， 并且使產品獲得了良好的長期穩定性和優秀的抗污染能力。
EE671風速變送器提供電纜型和接頭型兩種安裝方式。其風速測量范圍可達20m/s，模擬輸出方為0 - 1V, 0 - 5V 或0 - 10V的標準電壓信號。
產品的包裝盒內配有標準的安裝法蘭。安裝法蘭用于現場風速變送器的快速安裝， 同時，應確保探桿上的風速流向標記和風道中的實際風流方向相一致。
用戶可選用E+E專業的組態軟件，通過E+E專用數字通訊接口對變送器進行參數選擇和量程設置，并對探頭進行校準。
典型應用
- HVAC暖通空調系統
- 流量監測和控制
- 烘箱入口空氣監測

HVAC Miniature Air Flow Transmitter
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.
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 as linear voltage output 0 - 1 V, 0 - 5 V or 0 - 10 V.
The alignment strip on the probe and the matching mounting flange within the scope of supply simplify installation and correct positioning in the air flow. The flange enables the immersion depth to be infinitely variable.
With an optional configuration kit the user can set via a digital setup interface the output configuration and perform an adjustment of the probe.
Features
- High accuracy and long-term stability
- Outstanding resistance to contamination
- Easy and quick mounting
- User configurable
Typical Applications
- Heating and ventilation systems
- Flow monitoring and control
