  • Self-heated liquid level sensor
    Patent number: 7181965
    Abstract: A liquid level sensor comprising a thermistor probe and a power source connected to the thermistor probe to heat the thermistor probe. A cover encases the thermistor probe and includes openings allowing liquid to enter and exit an interior of the cover and contact the thermistor probe. A detector detects a liquid level in response to a voltage at the thermistor probe.

  • Sensor and temperature sensor capable of automatic installation
    Patent number: 7153024
    Abstract: A temperature sensor includes a substantially rod-shaped guide portion 28 vertically protruding from a vertical wall 20c of a substrate. A harness 40 is fixed to the guide portion 28 in a contacting state by accommodating the guide portion 28 and the harness 40 in a vinyl tube 44. Because of this configuration, a root portion of the harness 40, which extends from the substrate 20, is unlikely to be bent, broken or disconnected due to the rigidity of the guide portion 28.
