  • Sensing device and method
    Patent number: 8044811
    Abstract: The invention relates to a method and sensing device capable of determining a temperature of a liquid and an electrical conductivity of the liquid at the temperature. The sensing device comprises at least one temperature sensor for providing temperature measurement data arranged such that the temperature sensor is physically isolated from the liquid when the sensing device is immersed in the liquid. The device further comprises an electrical conductivity sensor, storage means containing temperature characteristics and a processor. The processor is arranged for instantly measuring an electrical conductivity of a liquid and for evaluating temperature measurement data for determining the temperature of the liquid on the basis of the temperature characteristics.
