Design of an Ultrasonic Transducer for Measuring Transient High Temperature

Aim\ To study a new sensor for measuring transient high temperature. Methods\ According to the ultrasonic theory, temperature of a gas can be deduced by the velocity of ultrasonic transmitting in the gas. The velocity is measured by using a specially designed ultrasonic transmitter and receiver. Results and Conclusion\ As this is a non contact temperature sensor with good dynamic response, it can be used in many testing situations such as the rocket launching, the burning in cylinders, the intaking of gas turbine and explosive exploding.
