【Abstract】 Based on that the dielectric permittivity of cell suspensions is monotonic function of the measuring frequency and cell concentration at radio-frequencies,a new method for detecting cell concentrations on-line and in-situ is proposed . An automatical detecting system and sensor are designed. The experiment results prove the feasibility of this detecting method and detecting system.更多还原
