HVAC用微型風(fēng)速變送器
EE671（EE575升級版本）系列是專為HVAC應(yīng)用而設(shè)計(jì)的一款緊湊型風(fēng)速變送器。
產(chǎn)品內(nèi)置VTQ型風(fēng)速敏感元件,該敏感元件結(jié)合了E+E研發(fā)的高品質(zhì)薄膜生產(chǎn)技術(shù)和*的塑封工藝的優(yōu)點(diǎn)。
它使用了新型的熱膜風(fēng)速工作原理，保證了測量的高精度和重復(fù)性， 并且使產(chǎn)品獲得了良好的長期穩(wěn)定性和優(yōu)秀的抗污染能力。
EE671風(fēng)速變送器提供電纜型和接頭型兩種安裝方式。其風(fēng)速測量范圍可達(dá)20m/s，模擬輸出方為0 - 1V, 0 - 5V 或0 - 10V的標(biāo)準(zhǔn)電壓信號。
產(chǎn)品的包裝盒內(nèi)配有標(biāo)準(zhǔn)的安裝法蘭。安裝法蘭用于現(xiàn)場風(fēng)速變送器的快速安裝， 同時(shí)，應(yīng)確保探桿上的風(fēng)速流向標(biāo)記和風(fēng)道中的實(shí)際風(fēng)流方向相一致。
用戶可選用E+E專業(yè)的組態(tài)軟件，通過E+E專用數(shù)字通訊接口對變送器進(jìn)行參數(shù)選擇和量程設(shè)置，并對探頭進(jìn)行校準(zhǔn)。

- HVAC暖通空調(diào)系統(tǒng)
- 流量監(jiān)測和控制
- 烘箱入口空氣監(jiān)測
EE671
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
- Inlet air monitoring in ovens

概覽
EE575 系列是專為大風(fēng)量環(huán)境應(yīng)用設(shè)計(jì)的一款緊湊型風(fēng)速變送器，小巧的設(shè)計(jì)使它可以應(yīng)用于許多不同的場合。EE575 使用E+E公司的薄膜敏感元件作為測量核心，基于熱膜風(fēng)速計(jì)原理研發(fā)出的高質(zhì)量敏感元件保證了測量的高精度和敏感度，創(chuàng)新的設(shè)計(jì)使益加義風(fēng)速計(jì)與傳統(tǒng)的熱絲式風(fēng)速計(jì)相比，對灰塵和其他污染的敏感度更低，測量的重復(fù)性和長期穩(wěn)定性更好。
EE575 安裝方便快捷，探頭桿上的對準(zhǔn)線與安裝法蘭能清楚的指示傳感探頭安裝的方向。安裝法蘭可隨意調(diào)節(jié)變送器探頭的插入深度。探桿內(nèi)的電子電路能提供一個(gè)線形的模擬輸出信號：0-5V 或 0-10V DC，對應(yīng)的風(fēng)速范圍可選 0...5m/s (0...1000ft/min) / 0...10m/s (0...2000ft/min)或者0...20m/s (0...4000ft/min)。
