Measurement of particles in oil using shear horizontal surface acoustic wave sensor
A shear horizontal surface acoustic wave (SH-SAW) device is used as a sensor for the liquid environment. As a main particle displacement of the SH-SAW is parallel in the propagation surface and perpendicular in the propagation direction, the SH-SAW does not radiate its energy into the liquid. Therefore, SH-SAW is suitable for the liquid measurement. In this paper, particles in oil are measured by using the SH-SAW. The experimental results show that the velocity and attenuation changes increase with increasing the amount of the iron particles. Whereas the velocity change obtained is qualitatively explained by the perturbation theory for the mass loading, the attenuation change cannot be explained. Therefore, it is necessary to develop the new theory for particle loading in oil environment.
