When fixing such an ultrasonic transducer to the wall surface of an object to be measured, if a space is partially created between the vibration surface of the ultrasonic transducer and the wall surface of the object to be measured, the propagation characteristics of the ultrasonic waves will be significantly affected. receive. Conventionally, when fixing an ultrasonic transducer, water, oil such as grease, paste, rubber film, etc. are interposed between the vibrating surface and the wall surface of the object to be measured.
The ultrasonic transducer was fixed by pressing it against the wall of the object to be measured using an appropriate tightening band.

When water is used, the water gradually decreases due to evaporation, so it cannot be used at high temperatures or for long periods of time. Furthermore, in the case of oil such as grease, when the temperature reaches high temperatures, the viscosity decreases and it flows out. Furthermore, in the case of rubber FFL film, although such evaporation and leakage do not occur, it is difficult to attach the vibrating surface of the ultrasonic transducer to the object to be measured if the wall surface is rough and rough.

It is an object of the present invention to provide a method for fixing an ultrasonic transducer that does not require any special attachment and is also suitable for soft objects to be measured.

算支障がなくなるという特長もある。[Effect of the invention 1] As is clear from the above detailed explanation, according to the method of fixing an ultrasonic transducer of the present invention, the oxime-free rubber seal adhesive is attached to the vibration surface of the ultrasonic transducer and the object to be measured. Since the ultrasonic transducer is fixed between the walls, not only is there little change in ultrasonic propagation characteristics over time, but the oxime-free rubber seal adhesive remains elastic even when it hardens, making it easy to use. Even if external vibrations are applied, there will be no positional deviation or change in signal level. Furthermore, even when the m-sound transducer is fixed to a hard vinyl hose or the like, it can sufficiently cope with slight twisting of the mounting surface. Furthermore, when fine powder dust is unavoidably attached, if it is thoroughly mixed with the adhesive and then adhered and solidified, it will be integrated and there will be no trouble.
