Title:
気温測定装置
Document Type and Number:
Japanese Patent JP7111352
Kind Code:
B2
Abstract:
To provide a temperature measuring device which can calculate a right temperature by estimating an error value of solar radiation from the output value of an optical sensor.SOLUTION: The temperature measuring device includes: a temperature sensor 20 detecting a temperature; an optical sensor 40 detecting an intensity of illumination; and a controller 70 for calculating an air temperature. The controller 70 corrects the detected temperature of the temperature sensor 20 by the output value of the optical sensor 40 and prevents the temperature from rising by solar radiation. It is preferable that the temperature measuring device includes the temperature sensor 20 and the optica sensor 40 in a first housing 10A containing a first air port 15 and a second air port 16 above the first air port 15, includes a second housing 50 above the second air port 16, and contains the controller 70 in the second housing 50.SELECTED DRAWING: Figure 1
