Product Name : System Pumped - SY Series
Product Description

What is a System Pumping Motorcycle Oxygen Sensor?


“System Pumped” oxygen sensor means that instead of using “Referenced Air” as reference for oxygen sampling, the ECU send constant voltages to the sensor to pump oxygen from the exhaust gas to the sensor for air referencing.  This action fills the sensor body with oxygen and thus continue the flow of ions between electrodes in accordance to Nernst Law.  Like regular oxygen sensor, this flow of ions produces voltages that feedback to the ECU for emission optimization.

CERADEX’s System Pumped Motorcycle Oxygen Sensor (SY Series) is perfect choice for EFI system designers who look for solutions for better and accurate emission control from more stable sensor voltage feeds, all in a tiny sensor package that saves design space.  SY Series is about half the size of our PM Series.  With full sensor body sealing, designers does not need to worry about water, pollutant, and oil intrusion that lower sensor durability and induce sensor breakage.

To ensure the highest quality and stability, every piece of sensor manufactured undergoes strict simulated bench for function check of both lambda voltage, as well as pressurized sealing bench for leakage check. With 25 years of experience in the field, choose CERADEX’s System Pumped Motorcycle Oxygen Sensor for your design needs.
