Abstract: An electric field sensor comprises an insulating substrate, a plurality of non-contacting electrodes disposed on the substrate, and a plurality of conductors coupled to the electrodes, and extending transversely through the substrate. The electrodes comprise a first electrode portion, and a second electrode portion interlaced with the first electrode portion. The conductors comprise a first conductor portion and a second conductor portion. The first portion of the conductors are coupled to the first electrode portion. The second portion of the conductors are coupled to the second electrode portion.

Abstract: A computer-based fibre production monitoring system includes at least one sensor, and a computer server in communication with the sensors. Each sensor is configured to provide data packets each being associated with a respective threadline and providing a measurement of at least one physical characteristic of a fibre as it is drawn past the sensor on the threadline and wound onto a bobbin. The computer server is configured to provide an analysis of the physical characteristics on a per-threadline basis and/or per-bobbin basis from the measurements. The sensor is configured as an electric field sensor, and includes an insulating substrate, non-contacting electrodes disposed on the substrate, and vias extending transversely through the substrate. The electrodes are interlaced with one another. One portion of the vias is coupled to one portion of the electrodes, and another portion of the vias is coupled to another portion of the electrodes.
