CONTACT TYPE INTERNAL THERMOMETER

摘要

Provided is a contact type internal thermometer including: a measurement surface that is brought into contact with a surface to be measured of a measurement object; a first temperature sensor stack including a first measurement surface side temperature sensor arranged on a measurement surface side, and a first back surface side temperature sensor arranged on a back surface side; a second temperature sensor stack including a second measurement surface side temperature sensor arranged on a measurement surface side, and a second back surface side temperature sensor arranged on a back surface side; and a controller configured to calculate an internal temperature of the measurement object based on measurement results of the respective temperature sensors, in which the first back surface side temperature sensor and the second back surface side temperature sensor have different surface areas.

1. A contact type internal thermometer, comprising:
a measurement surface that is brought into contact with a surface to be measured of a measurement object so as to calculate an internal temperature of the measurement object; a first temperature sensor stack comprising a first measurement surface side temperature sensor arranged on a measurement surface side of a first flexible printed board, and a first back surface side temperature sensor arranged on a back surface side of the first flexible printed board; a second temperature sensor stack comprising a second measurement surface side temperature sensor arranged on a measurement surface side of a second flexible printed board, and a second back surface side temperature sensor arranged on a back surface side of the second flexible printed board; and a controller configured to calculate the internal temperature of the measurement object based on measurement results of the first measurement surface side temperature sensor, the first back surface side temperature sensor, the second measurement surface side temperature sensor, and the second back surface side temperature sensor, wherein the first back surface side temperature sensor and the second back surface side temperature sensor have different surface areas.
