The invention discloses a friction nanometer generator-based pressure type
thermometer and a temperature measuring method thereof. The friction nanometer generator-based pressure type
thermometer comprises a
temperature sensing working medium, a liquid friction medium, an isolation medium, a gas buffer medium, a
temperature sensing shell and a
solid friction medium. According to the friction nanometer generator-based pressure type
thermometer and the temperature measuring method thereof of the invention, the liquid friction medium, the isolation medium and the gas buffer medium are utilized toperform sealing, so that the leakage of the
temperature sensing working medium is avoided; and the pressure of the temperature sensing working medium is obtained through the potential of an electrodelayer, so that online real-time
temperature measurement can be achieved. The structure of the friction nanometer generator-based pressure type thermometer is simple in structure and are insusceptibleto the influence of local
atmospheric pressure; the measurement result of the thermometer is convenient for long-distance transmission; and the thermometer can still read temperature on site under the condition of complete power failure. According to the friction nanometer generator-based pressure type thermometer of the invention, the
mechanical energy of the temperature sensing working medium in a
temperature measurement process is converted into
electric potential energy, and self-energized
temperature measurement is achieved. The friction nanometer generator-based pressure type thermometer has the advantages of simple structure, high precision, capability of achieving real-time measurement, self-energized operation, environmental friendliness, high efficiency and the like and has a great application prospect in the fields of material science,
medical treatment and health, environmental science, the
chemical industry and the like.
