The piezoelectric ceramic element in the piezoelectric ceramic ultrasonic transducer is very sensitive to temperature, the higher the temperature is, the lower the electroacoustic conversion efficiency of the transducer is, and when the temperature rises to a certain value, the piezoelectric ceramic element loses the piezoelectric effect and even is directly damaged; the ultrasonic transducer can generate a heating phenomenon due to self consumption or the influence of external environmental factors in the working process, particularly the ultrasonic transducer working in a high-power state has extremely serious heating phenomenon, the larger the output power of the ultrasonic transducer is, the more serious the heating is, the position with the most serious heating is the center of the piezoelectric ceramic element, and the heat dissipation is generally carried out in an air cooling mode at present, namely, an axial flow fan is utilized to blow air to the transducer, although the surface temperature of the piezoelectric ceramic element is reduced by the air cooling energy, the internal heat of the piezoelectric ceramic element cannot be rapidly dissipated due to the poor heat conduction performance of the material of the piezoelectric ceramic element, and the temperature of the center of the piezoelectric ceramic element is still extremely high at the moment; the ultrasonic transducer is not provided with a temperature monitoring device, once the axial flow fan is damaged, the ultrasonic transducer can work in a high-temperature state, the working efficiency is extremely low, and the ultrasonic transducer is easily damaged; at present, some manufacturers can paste a temperature switch on the surface of the ultrasonic transducer, connect the temperature switch into an ultrasonic generator through an electric wire, and stop the ultrasonic transducer when the temperature rises to a certain value due to the action of the switch, but the disadvantage of the method is that: the wiring difficulty and workload of field installation are increased, and especially the workload and difficulty of remote control are higher; (II) the requirement of continuous operation cannot be met in the industry requiring continuous ultrasonic operation; and (III) the temperature switch attached to the surface of the ultrasonic transducer cannot detect the temperature of the highest heating point in the center of the piezoelectric ceramic element in the ultrasonic transducer, so that the ultrasonic transducer with the built-in wireless temperature measurement transmitting module is necessary.
