The sensor includes a tube and three or more conductors which are wound in a continuously parallel helix around the tube such that the conductors are interleaved. The tube is non-porous and electrically insulative. Both the proximal end and the distal end of the tube are open. Each turn of each conductor is equally spaced from the adjoining turns of the other conductors, and the conductors have a common helical length. The sensor can also include a first cap which seals the proximal end of the tube and a second cap which seals the distal end of the tube such that the interior of the tube is always filled with air."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Helical sensor for testing a composite medium","description":"A sensor is provided for testing a composite medium.
