Microwellenresonator, textile machinery with such a resonator and space unit of such resonator

It is a microwave resonator for or on a textile machine for connection to a measuring device for measuring the mass and / or moisture from continuously through the resonator chamber (31; 331; 431; 531) conveyed fiber material (FB) have been proposed. The object of the invention is to configure the resonator such that the measuring accuracy is improved. For this purpose, various advantageous embodiments are at least one electrically non-conductive space unit (60; 160, 161; 303. 307; 403, 407; 503; 603, 607) for disposition within the resonator cavity (31; 331; 431; 531) are proposed.
