  • Patent number: 8137625
    Abstract: A urea sensor includes a detecting portion which, in use, is immersed in a liquid accommodated in a urea solution tank for detecting the thermal conductivity of the liquid to detect whether the liquid accommodated in the urea solution tank is an aqueous urea solution; and an enclosing member enclosing a periphery of the detecting portion and including one or more vents penetrating the enclosing member. At least one of the vents is a lower vent being of a configuration and size such that a first hypothetical circle having a diameter of not less than 3.5 mm can be wholly contained within the lower vent. At least a portion of the lower vent is positioned below the detecting portion when the urea sensor is positioned for installation in the urea solution tank.
