Diesel Exhaust Back-Pressure Sensors

Kavlico, part of Custom Sensors & Technologies (CST), is offering a line of emission sensors for measuring diesel engine exhaust back-pressure (EBP). The sensors can withstand operating temperatures of -15ºC to +125ºC, Kavlico said. Protecting an engine from damage due to over-pressure situations in systems with or without a diesel particulate filter (DPF), Kavlico’s EBP sensors are designed to provide diagnostic information to the engine control unit for regeneration of the DPF.

Kavlico’s proprietary ASIC architecture, calibration, and compensation methods, along with the ceramic capacitive sense element make these sensors applicable for operation in the exhaust environment where there is severe vibration and caustic soot and acids. The sensors feature stainless steel housings and operate on 5 Vdc power supply, providing a linear amplified analog output of 0.5 to 4.5Vdc proportional to pressure. The available pressure ranges are (0 - 5.80 and 0 - 7.975 psig or 0 - 400 mBar and 0 - 500 mBar). The low power consumption, humidity tolerant sensors are EMI/EMC protected, exhibit low hysteresis, and also have short circuit and reverse polarity protection, Kavlico said.

Kavlico said its EBS sensors can be custom-configured with application-specific electrical and process connections. Custom pressure ranges, outputs, accuracy, and packaging is also available.
