Abstract
Apparatus and method for identifying type and distillation properties of light oil. A pulse voltage is applied for a predetermined period of time to a liquid type identification sensor heater comprising a heater and an identification liquid temperature sensor provided in the vicinity of the heater; the light oil to be identified is heated by the heater; and the liquid type is identified with a voltage output difference V0, corresponding to a temperature difference between the initial temperature and the peak temperature of the identification liquid temperature sensor.
Claims20
A liquid type identification apparatus for a light oil, for identifying the type and distillation properties of a light oil, comprising:
- a liquid type identification chamber for a light oil, for allowing a light oil to be identified, which has been introduced into a liquid type identification apparatus body, to temporarily stay therein;
- a liquid type identification sensor heater provided within the light oil type identification chamber;
- and
- a liquid temperature sensor spaced by a given distance from the liquid type identification sensor heater and provided within the light oil type identification chamber,
- the liquid type identification sensor heater comprising a heater and an identification liquid temperature sensor provided in the vicinity of the heater,
- the liquid type identification apparatus further comprising an identification control unit;
- the identification control unit being constructed that a pulse voltage is applied to the liquid type identification sensor heater for a predetermined period of time, and the light oil to be identified which temporarily stays within the liquid type identification chamber for a light oil is heated by the heater, and the liquid type is identified with a voltage output difference V0, corresponding to a temperature difference between the initial temperature and the peak temperature of the identification liquid temperature sensor.
