Design of Test System for Limiting Current Oxygen Sensor

Designed a set of system used to test the performance of limiting current type oxygen sensor.The test system contains mainly gas injection and ventilation set,rate of flow control and measure set,power supply and heat set,temperature control and test set,test circuit,etc.So it can simulate all the situations of the oxygen sensor's workspace very well,and can meets the requirement of the performance testing of limiting current type oxygen sensor.In addition,the system can test the performance of differential concentration type and semiconductor resistive type oxygen sensors while relevant test circuit was designed.
