MICROWAVE RESONATOR, TEXTILE MACHINE COMPRISING SUCH A RESONATOR AND DIELECTRIC FOR SUCH A RESONATOR

摘要

A microwave resonator for or on a textile machine, especially a machine for carding, drafting, or combing, for connection to a measurement apparatus for the measurement of the thickness and/or the water content of fiber material (FB), which is continually being transported through the said resonator space (31), whereby, in the resonator (30), at least area-wise, at least one electrical, non-conducting dielectric (460; 460a, 460b) is provided, the dielectric constant of which remains essentially unchangeable at normal machine operational temperature variations, and whereby at least two tubes (460a, 460b), open at each end facing, are provided and placed in the resonator (30) which serve as said dielectrics characterized in that an inner guide tube (460b), which is provided for the throughput of fiber material (FB), is exchangeably inserted into an outer rube (460a).
