詳細(xì)介紹
EE046冷凝報(bào)警器有助于防止冷凝梁和其他關(guān)鍵冷點(diǎn)上的冷凝，并適用于安裝在平面和直徑為50毫米（2 "）的管道上.
當(dāng)物體表面周?chē)目諝庀鄬?duì)濕度（RH）達(dá)到RH時(shí)，表面會(huì)發(fā)生冷凝. 依靠與表面非常好的熱耦合，EE046可精確測(cè)量表面溫度下的空氣相對(duì)濕度.
在冷凝實(shí)際發(fā)生之前，繼電器輸出會(huì)在接近冷凝條件時(shí)發(fā)出預(yù)警. 該產(chǎn)品還會(huì)提示電源故障或電纜損壞. 狀態(tài)LED燈指示正常運(yùn)行，冷凝危險(xiǎn)或電源故障.E+E涂層保護(hù)濕度敏感元件免受灰塵和污染物影響.

EE046 condensation monitor is used for detecting the danger of condensation on pipes, ducts and other surfaces before condensation actually occurs.
The device measures the relative humidity at the surface to be monitored and provides an early warning signal (relay) when the humidity reaches 90% RH.
The signal can be used for initiating control steps such as increasing the water temperature in a chilled ceiling, reducing the cooling capacity or switching on the heating.A special coating protects electronics and sensor against contamination.
Key Features
- Early detection of condensation danger
- High accuracy and long term stability
- Compact design
- Fast response time
- Sensor protection
- Easy mounting and wiring
- LED status indication
Typical Applications
- Chilled ceilings
- HVAC, buliding automation
- Rectifier cabinets for wind power generatiors
- Switching and electronics cabinets
EE46結(jié)露報(bào)警器可以用來(lái)監(jiān)測(cè)制冷天花板的結(jié)露狀況，防止暖通空調(diào)系統(tǒng)在臨界點(diǎn)發(fā)生結(jié)露，它還可作為運(yùn)行于臨近露點(diǎn)附近其他系統(tǒng)的結(jié)露監(jiān)控。
由于結(jié)露報(bào)警器的溫度與環(huán)境溫度相一致，露點(diǎn)的測(cè)量實(shí)際是對(duì)相對(duì)濕度的測(cè)量，結(jié)露報(bào)警器基于高品質(zhì)電容型濕敏元件來(lái)測(cè)量接近露點(diǎn)時(shí)的相對(duì)濕度。在達(dá)到 90% RH 的切換點(diǎn)時(shí)，結(jié)露報(bào)警器會(huì)為后續(xù)控制程序（如增加水溫、降低制冷功能，打開(kāi)加熱系統(tǒng)等）的啟動(dòng)提供動(dòng)作條件，并發(fā)出報(bào)警輸出信號(hào)。報(bào)警器上的狀態(tài)指示燈能及時(shí)提醒用戶有結(jié)露危險(xiǎn)。
產(chǎn)品經(jīng)過(guò)特殊的鍍膜處理后，能有效保護(hù)電子部件及敏感元件免受環(huán)境污染的影響。
