A wireless electrical resistance detector has been developed in order to measure the real-time particle volume fraction in a centrifuge for controlling a rotational velocity and particle supply rate. The developed detector was attached around a cylindrical vessel to be mock a centrifuge. With the developed detector, the particle volume fractions in sodium chloride solution were measured under experimental conditions of various rotational velocities, particle supply rates and measurement cross section positions. The particle volume fractions are increased as the rotational velocities and the particle supply rates are increased, and the particle volume fraction is decreased as the measurement cross section position is increased. The measured particle volume fractions coincide with an anticipated tendency of particle volume fraction. The appropriateness of measurement results is qualitatively validated.
