Abstract: Sensored mixer, comprising a mixing device for mixing two or more components to produce a mixed liquid at a mixer output, and a property sensor for determining a property of a liquid, the property sensor comprising a) a channel comprising a sensing zone through which the liquid flows; b) two electrodes for generating an electric field of one or more sensing frequencies in the sensing zone; c) a data storage device comprising a pre-stored set of calibration data representing calibration impedance responses measured previously at the one or more sensing frequencies and at different property values of the property of an identical liquid; and d) a device to repeatedly i) generate between the electrodes an electric field of in the sensing zone; ii) sense between the electrodes, a response impedance; iii) derive from the response impedance a property value of the property of the liquid, using the pre-stored set of calibration data representing calibration impedance responses, wherein the property sensor is in fluid communication with the mixer output such that the mixed liquid can flow from the mixer output through the sensing zone. A method for sensing a property of the liquid and a data set of calibration data representing calibration impedance responses usable with the sensor and the method are also disclosed.

Abstract: Multilayer damping material for damping a vibrating surface (10) including: at least one constraining layer (4); at least one dissipating layer (1, 3); at least one kinetic spacer layer (2) including multiple spacer elements (2b), the kinetic spacer layer being arranged between the constraining layer and the vibrating surface, when used for damping the vibrating surface, wherein each spacer element has opposite ends, at least one end of each of the multiple spacer elements is embedded in, bonded to, in contact with or in close proximity to the dissipating layer, such that energy is dissipated within the multilayer damping material, through movement of the at least one end of each of the multiple spacer elements; absorbing material as at least one additional layer (12) or within at least one of the above layers.
