EE820采用的是E+E單光源雙光速紅外線測量技術，可自動進行光源老化補充，并具有較高的抗污染能力，從而保證了產(chǎn)品的長期穩(wěn)定性。為了應對提高響應時間的要求，EE820過濾器的背面安裝了一個風扇，用于加速被測空氣的循環(huán)和流動。
配備的IP54防護等級的外殼和特殊的過濾器，使EE820可以應用在污染工況中，例如農(nóng)業(yè)和畜牧業(yè)。在進行清潔操作前，使用M12接頭可以方便拆除變送器。
典型應用
益加義技術--CO2自動校準程序采用了雙光源雙光束方法，通過測量固定波長的紅外線光強，將其轉換為CO2的吸收量。
兩個紅外線光源有著不同的工作周期：其中一個紅外光源作為測量光源，每隔30秒測量一次CO2濃度，并發(fā)送測量信號。另一個紅外光源作為對比光源，僅在自動校準時工作，每24小時被激活2次。對比光源的工作時間很短，老化漂移量可以忽略，因此可用來定期精確校準測量光源?！?/p>
益加義公司擁有多年薄膜技術的研發(fā)經(jīng)驗和現(xiàn)代化的潔凈室車間。紅外測量單元的測量腔體鍍金工藝和組裝工藝均在高等級的潔凈室完成，這對儀表長期穩(wěn)定的測量十分重要。

SupplyThe EE820 is designed for use in harsh, demanding applications. A multip-point CO2 and temperature factory adjustment procedure leads to an excellent CO2 measurement accuracy over the entire temperature working range.
The EE820 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability.For fast response time requirements there is an EE820 version with forced air circulation created by a fan installed behind the filter.With its robust, functional housing and a special integrated filter the EE820 can be installed in polluted applications such as agriculture and livestock barns. The M12 connector option facilitates easy removal of the EE820 before site cleaning operations.
An optional kit facilitates easy configuration and adjustment of the EE820.
