Product Details


Process of Zirconia Plate Heater Chip for Oxygen Sensor

The zirconia ceramic plate B structure as show in Figure 1, the zirconia chip includes five layers, and they are protective layer, electrolyte layer, air layer, base layer and heating layer. 

The protective layer system includes electrode pad, porous protective layer and aluminum oxide layer.

The electrolyte layer system includes inner / outer electrode, YSZ electrolyte layer. And the airway layer consists of airway, alumina layer.

The base layer has a number of alumina layers (Can adjust based on customer requirements on the product thickness). The heater layer system includes heater, heater pad and oxidation Aluminum layer.


Engine Test of Zirconia Plate Heater Chip for Oxygen Sensor

After the assembly of the product, then test the leak rate under the temperature of 25℃± 10℃and the air pressure of 3.4 bar, and the engine bench test is carried out under the condition that the leakage rate is less than 0.2 cm3/ min.

Recommended Use Conditions

Conventional operating temperature range: 350℃~850℃

Maximum continuous operating temperature (250 h): 1000℃

Should be used in accordance with the provisions of the GB 17930 gasoline and meet the GB 18351 requirements of the vehicle ethanol gasoline.
