Abstract

Industrial microwave sensors for technological processes dealing with sedimentable substances are considered These sensors are based on the use of waveguide resonators supporting TE_01n-modes. Inherent to them zero electric field at metal surfaces provides significant reduction of influence of dielectric sediments on measurements results. As examples circular and coaxial waveguide resonator-based sensors of liquid level in tanks are described. Methods for suppression of undesirable modes are described
