Abstract:
The present disclosure describes a device and corresponding method for measuring tar in a tar environment, e.g., a tar producing environment such as a stove or a combustion engine, based on UV absorption spectroscopy. A first measurement along an optical path in the tar environment is performed at a wavelength less than 340 nm at which both tar and non-tar elements absorb. This measurement is compensated for non-tar absorption by means of a second measurement at a wavelength equal to or greater than 340 nm at which tar does not absorb. From the non-tar compensated absorbance value a measure of tar in the tar environment is derived and an air intake in the tar environment is regulated based on the measure of tar.

Claim (Index 44):
A method for measuring tar inside a tar-environment and for controlling a level of air intake in the tar-environment, comprising the steps of:\n generating light from at least one light generating element, emitting light into the tar environment such that the light has: i. a first wavelength less than 340 nm, whereby light is absorbed by both tar-elements and non-tar elements; and ii. a second wavelength equal to or greater than 340 nm, whereby light is absorbed by non-tar elements; directing the light onto at least one light detection element, such that said light has an optical path length through the tar-environment; obtaining a first light signal from the light having the wavelength less than 340 nm; obtaining a second light signal from the light having the wavelength equal to or greater than 340 nm; deducing a first absorbance value from the first light signal; deducing a second absorbance value from the second light signal; deducing a non-tar compensated absorbance value by relating the second absorbance value to the first absorbance value; correlating the non-tar compensated absorbance value to a measure of tar inside the tar-environment; and adjusting the level of the air intake based on the measure of tar inside the tar-environment.
