Kavlico’s Exhaust Back-Pressure Sensors Help Maximize Engine Performance

Kavlico, a global company of Custom Sensors & Technologies (CST), has in their portfolio, a line of emission sensors for measuring exhaust back-pressure that aid in maximizing engine performance and efficiency. Robust and highly reliable, these high accuracy sensors can withstand operating temperatures of -15°C to +125°C.

Protecting the engine from damage due to over-pressure situations in systems with or without a Diesel Particulate Filter (DPF), Kavlico’s EBP sensors provide vital diagnostic information to the Engine Control Unit (ECU) for regeneration of the DPF.

Kavlico’s proprietary ASIC architecture, calibration, and compensation methods, along with the ceramic capacitive sense element make these sensors an ideal fit 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 also EMI/EMC protected, exhibit low hysteresis, and also have short circuit and reverse polarity protection.

Kavlico EBS sensors can be custom-configured with application-specific electrical and process connections to suit each individual OEM’s requirement. Custom pressure ranges, outputs, accuracy, and packaging is also available.
