High-temperature ultrasonic transducer

The utility model relates to the field of high-temperature fluid speed measurement, in particular to a high-temperature ultrasonic transducer. The high-temperature ultrasonic transducer provided by the utility model comprises a reinforcing module, a liquid waveguide module and a piezoelectric module, wherein the reinforcing module is arranged at one end of the liquid waveguide module, and the reinforcing module is in contact with high-temperature fluid; the end, deviating from the reinforcing module, of the liquid waveguide module is fixedly connected with the piezoelectric module. According to the utility model, the reinforcing module is used as a detection front end in contact with high-temperature fluid, so that the defects that the front wall structure of the liquid waveguide module is weak and is easy to deform and break in a continuous high-temperature environment are overcome; meanwhile, the liquid waveguide module can be matched with a plurality of piezoelectric elements, ultrasonic aliasing caused by
