Radio Frequency Diesel and Gasoline Particulate Filter Sensor


The CTS RF Sensor (RF-DPF, RF-GPF) is a radio frequency (RF) -based sensor, used to directly measure the state of diesel and gasoline emissions control systems. The technology provides real-time measurements and feedback control based on the actual loading state of particulate filters and catalysts in an on-vehicle sensor, not possible with current sensors in the market. The CTS RF sensor helps enable engine and vehicle manufacturers to meet increasingly strict, real-world emissions regulations, while reducing fuel consumption and decreasing the overall emissions system cost and complexity.
