Device and method for measuring a product characteristic with a microwave dispersion range sensor assembly

摘要

The device has a micro-wave scatter field sensor arrangement i.e. micro-strip conductor arrangement, comprising a product chamber arranged outside a microwave- scatter field resonator. A micro-wave generation device generates a micro-wave field in the resonator. An evaluation unit evaluates a signal for determination of product characteristics. The evaluation device is arranged for determination of the characteristics in dependent upon measurement values (G1, G2), which are associated with micro-wave damping of operating modes, whose resonance frequency ranges to three giga-hertz. An independent claim is also included for a method for measuring the characteristics of the product.
