PYROMETER OF SPECTRAL RATIO Russian patent published in 2013 - IPC G01J5/60 

FIELD: measurement equipment.

SUBSTANCE: pyrometer of spectral ratio comprises a lens, which fixes an image of a controlled body on a photodetector, in front of which a radiation filter is installed, an amplifier of a photodetector signal, a microprocessor with two analogue-to-digital converters, a temperature indicator and a power supply element. Additionally, a switch controlled by a microprocessor is introduced, one pole of which is connected to a power supply element, and the second one - to the amplifier's input, at the same time the common pole of the switch is connected to the photodetector.

EFFECT: simplified design of a spectral ratio pyrometer, higher sensitivity of a spectral ratio pyrometer.
