Patents by Inventor Raymond B. Litteaur

Raymond B. Litteaur has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190226916
    Abstract: A temperature sensing assembly includes first and second temperature sensors disposed within an elongate mineral insulated conductive sheath. A junction point of the first temperature sensor is electrically connected to the conductive sheath. The second temperature sensor is electrically isolated from the conductive sheath. Measurements obtained from the electrically isolated temperature sensor can be used to test insulation resistance of the assembly or temperature indications from the electrically isolated temperature sensor can be compared to measurements taken from the electrically connected junction point to take a variety of corrective actions during use of the temperature sensing assembly, such as adjusting the installation of the assembly or applying correction factors to measurements obtained from one of the temperature sensors.
