ABSTRACT:
A sensor comprising a heating element and a temperature detecting element used to measure a temperature of the heating element are both held out of contact with each other within a sensor protecting tube. For fluid exhibiting slow changes in its state as time elapses, a fluid state is measured on the basis of a differential temperature between temperatures prior to and during heating of the heating element. For the fluid exhibiting rapid changes in its state as time elapses, the sensor is caused to generate heat while the temperature of this sensor is measured, and a separate temperature measuring sensor measures the temperature of the fluid. The fluid state is determined on the basis of the differential temperature between the temperatures of the sensor and the temperatures of the fluid.
