CDX系列二氧化碳傳感器是一種低成本、高性能的二氧化碳傳感器。 該產(chǎn)品通過(guò)與樓宇自動(dòng)化系統(tǒng)協(xié)同工作，讓用戶(hù)毫不費(fèi)力地有效控制進(jìn)入?yún)^(qū)域的新鮮空氣，從而提供即時(shí)的節(jié)能效果。 使用CO2傳感器的按需通風(fēng)可以在保持室內(nèi)空氣質(zhì)量的同時(shí)防止過(guò)度通風(fēng)造成的能量損失。 該系列CDX變送器采用了的自動(dòng)背景校準(zhǔn)(ABC)邏輯自校準(zhǔn)系統(tǒng)。 ABC邏輯實(shí)際上消除了在室內(nèi)二氧化碳水平在空閑期間下降到室外水平的手動(dòng)校準(zhǔn)的需要。
