尿素液位传感器介绍
为了降低柴油车尾气所含氮氧化物(NoX)排放浓度,应对日益严厉的尾气排放标准,选择性催化还原系统(SCR)应运而生,SCR系统利用尿素溶液催化还原NoX.Ad系列高品质液位传感器专为柴油车SCR系统配套设计,产品用于检测尿素溶液(AdBlue)液位。Ad系列液位传感器利用多个舌簧开关并联构成的电阻回路来指示液面高低，传感器的长度，安装方式可以根据客户要求灵活调整。相比其他类型的液位测量技术，无需复杂电路，实施简单，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.
