Abstract

The invention discloses an infrared radiation measuring device. The infrared radiation measuring device comprises a shell, a first thermosensitive element and a second thermosensitive element, whereinthe shell is provided with a first cavity and a second cavity corresponding to the first thermosensitive element and the second thermosensitive element; a heat absorption element is arranged on the periphery of the first thermosensitive element; the first thermosensitive element and the heat absorption element are both arranged in the first cavity; the shell is provided with a light-transmittingwindow corresponding to the first thermosensitive element; external infrared radiation is radiated to the heat absorption element through the light-transmitting window and conducted to the first thermosensitive element, and therefore the external infrared radiation is measured.

Description

【Technical field】 [0001] The invention belongs to the field of testing equipment, in particular to an infrared radiation measuring device. 【Background technique】 [0002] The external thermal radiation measurement device is composed of optical system, photodetector, signal amplifier, signal processing, display output and other parts. The optical system collects the target infrared radiation energy in its field of view, and the size of the field of view is determined by the optical parts and position of the external thermal radiation measurement device. Infrared energy is focused on a photodetector and converted into a corresponding electrical signal. The signal is converted into the temperature value of the measured target after being calibrated by the amplifier and signal processing circuit according to the internally set algorithm and target emissivity. However, the circuit in the prior art is too complicated and the precision is too low, so it is not suitable for some s...
