為了降低柴油車尾氣所含氮氧化物(NoX)排放濃度,應對日益嚴厲的尾氣排放標準,選擇性催化還原系統(SCR)應運而生,SCR系統利用尿素溶液催化還原NoX.Ad系列高品質液位傳感器專為柴油車SCR系統配套設計,產品用于檢測尿素溶液(AdBlue)液位。Ad系列液位傳感器利用多個舌簧開關并聯構成的電阻回路來指示液面高低，傳感器的長度，安裝方式可以根據客戶要求靈活調整。相比其他類型的液位測量技術，無需復雜電路，實施簡單，成本低，可靠性高。
In order to fulfill the legislation on the reductions of emission of Nitrogen Oxidaes(NOx) from diesel engine,after treatment systems, such as SCR(Selective Catalytic Reduction) has been developed to reduce NOx,SCR technology converts the NOx exhaust fumes into harmless water and nitrogen by chemical reaction of urea in a catalyst in the exhaust gas steam.Our state of arts AD series level sensor is designed for SCR system, and to detect the level of AdBlue.The measurements are done by a series of reed switches positioned inside the level tube,a float with built in magnet moving up and down when fluid level changes, would triger the reed switches inside the tube respectively, thus, generate a potential free resistance signal with a Ohm value to indicate the change of fluid level.Compare to other level sensing technologies, AD series of level sensor without complex electronic circuit,is a simple, robust solution for AdBlue tanks.
