AOF1010 Short Term Ultrasonic Oxygen Sensor For Oxygen Gas Flow Concentration Sensing
Product Overview:
The AOF1010 ultrasonic oxygen sensor is an ideal, cost - effective, and practical oxygen concentration detection module based on the ultrasonic principle. It has the characteristics of high - precision, high - reliability, and ease of use, and can simultaneously detect concentration, flow, and temperature. It is widely used in agriculture, industry, commerce, environmental testing, especially in the oxygen generator industry.
Working Principle:
According to the physical transmission characteristics of ultrasonic waves, the sensor calculates the oxygen concentration by detecting the sum of the downstream and upstream times, and calculates the oxygen flow rate by detecting the difference between the downstream and upstream times. The temperature - measuring module in the sensor can detect the gas temperature and perform real - time temperature compensation on the gas concentration and flow rate through an algorithm.
