    摘要： A thermal sensor in which, when an object to be measured is a water-based liquid, attachment of air bubbles to the external surface of the sensor is reduced to improve measurement accuracy. The thermal sensor has a sensing element (21a) including a heat producing body and a temperature sensing body, a resin mold (23) for sealing the sensing element (21a), and a heat transmission member (21c) for transmitting heat between the sensing element (21a) and a water-based object to be measured. A part of the heat transmission member (21c) is exposed from the resin mold (23) to form an exposed surface section. A hydrophilic film (50) formed of a silicon oxide film is applied to the exposed surface section and to that part of the surface of the resin mold which is positioned around the exposed surface section.

    摘要： The types of gasolines having different distillation characteristics and various compositions are identified accurately and rapidly. A pulse voltage is applied for a predetermined time to a liquid type identifying sensor heater including a heater and an identifying liquid temperature sensor provided in the vicinity of the heater and an identified gasoline is heated by the heater and the liquid type is identified with a voltage output difference V0 corresponding to a temperature difference between an initial temperature and a peak temperature in the identifying liquid temperature sensor. Furthermore, a gasoline is introduced between electrodes of an alcohol concentration detecting sensor, and a change in a specific inductive capacity of the gasoline between the electrodes is measured with an oscillation frequency thereby detecting an alcohol concentration in the gasoline. Moreover, based on the alcohol concentration detected by the alcohol concentration detecting device, correcting liquid type identification data in the identification control portion on the basis of alcohol concentration data which are prestored in the identification control portion, thereby identifying a liquid type.
