The ultrasonic measurement technology is more and more widely used

there is some advantages that the temperature measurement in the air with ultrasonic in some special working condition. The theory that the air temperature is measured by the ultrasonic is analyzed. The experimental platform for measuring the temperature in the air is built. The temperature measurement of the constant temperature and a certain gradient temperature field in the air by ultrasonic is studied. The experimental results show that the error of air temperature measurement by ultrasonic is small

which proves that it is feasible to measure air temperature based on ultrasonic. This proves that it is feasible to measure the temperature in the air by ultrasonic wave under different working conditions. It provides technical support and lays the foundation for temperature measurement in the air under different conditions by ultrasonic.
