Planar Ceramic Heater Sticks for DENSO Oxygen Sensor

Oxygen sensors are designed to monitor the amount of oxygen that's in the car's exhaust stream, while ceramic heating element plays an important role in O2 sensor. During heating, zirconia conducts oxygen ions, a characteristic that allows oxygen ions to flow from the high O2 concentration of air to the low O2 concentration on the exhaust side of the ceramic.

The oxygen sensor is an essential component on engines using three-way catalytic converters to reduce exhaust pollution. It uses ceramic sensitive elements to measure the oxygen potential in the exhaust duct of the car. There are two kinds of oxygen sensors in practical application: zirconia oxygen sensor and titania oxygen sensor.

Compared with traditional oxygen sensor is made of alumina and inserts into a zirconia ceramic tube and commonly takes 20 seconds to activate.
