Introduction: What is an Oxygen Sensor? An oxygen sensor is a key device for measuring the oxygen concentration in exhaust gas. At its core, the sensor relies on a zirconia or ceramic sensing element, supported by a built-in heater, which provides real-time feedback to the engine control unit (ECU). This feedback ensures that the engine maintains an ideal air-fuel ratio, thereby enhancing fuel efficiency, reducing emissions, and improving the overall performance of the engine.   Applications of Oxygen Sensors Automotive   Installed both upstream and downstream of catalytic converters   Fundamental to meeting emission compliance standards (OBD-I and OBD-II)   Industrial They are widely used in boilers, furnaces, and other combustion monitoring systems.   Environmental Applied in gas detection, air quality monitoring, and safety systems   Types of Oxygen Sensors (Bosch Case Study)   Thimble Sensors: Traditional ceramic type, highly durable, requiring an ...

 Innovacera Ceramic Oxygen Sensor Heater is suitable for use in Bosch, Denso, Delphi, NTK & NGK Oxygen Lambda Sensor, Oxygen sensors are designed to monitor the amount of oxygen that’s in the car’s exhaust stream, while ceramic heater plays an important role in the 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. Innovacera produces ceramic heating rods and planar ceramic sensor elements, the rod shape is used for the thimble oxygen sensor and the planar ceramic heater is used for the planar oxygen sensor.

The core component inside an oxygen sensor is the zirconia ceramic heating element, which will heat the O2 concentration on each side, turn the O2 to the voltage signals and send to the ECU. Innovacera provides three types of oxygen sensor chip that can help to improve the performance of the oxygen sensor: 1. SWITCH TYPE OXYGEN SENSOR 2. WIDE BAND OXYGEN SENSOR 3. AIR-FUEL RATIO SENSOR Till now, those zirconia ceramic heating element has been used on the automotive such as TOYOTA, LEXUS, AUDI, Santana, Magotan, etc.
