  • Temperature sensor
    Publication number: 20020090019
    Abstract: A temperature sensor is provided which includes a measurement element, which changes its electrical resistance when the temperature changes. The measurement element is located in a protective sleeve, which may be provided with openings. A terminal-side area of the measurement element including its terminals and the surrounding area of the protective sleeve is potted in a temperature-resistant, electrically nonconductive material. The terminals are connected directly to two conductors within a jacketed tube.
