Work features of titanium oxide sensor:

The structure of titanium dioxide type auto o2 sensor is shown in the figure. The titanium dioxide 

element is embedded with a platinum-shaped platinum electrode and is surrounded by ceramics. 

At one end of the insulator is the titanium dioxide element and thermistor, which leads to three leads 

from the junction of the poles and two components. On the surface of the insulator, the tungsten wire 

is wound around it as a heater for car lambda sensors and leads to two leads. When there is more 

oxygen around, the resistance of titanium dioxide increases. Conversely, when oxygen is small, around 

the resistance of the titanium dioxide is reduced, so the resistance of titanium dioxide car o2 sensor, a 

sharp change in the direction of the theory air-fuel analogy nearby is dramatically changing the output 

voltage. The customizde oxygen sensor made of titanium dioxide has three terminals, namely "reference

power", "output" and "iron". The thermo-sensitive resistance in series with titanium dioxide element is used 

to compensate the temperature. When the temperature is very low, the resistance of titanium dioxide is very 

large and can't work properly, so the sensor is equipped with a heater.
