摘要

"Fototu00e9rmico sensor and method for the analysis of materials by indirect impact of electromagnetic energy.The present invention consists of a sensor fototu00e9rmico for analysis of solid materials in form of powder, and liquid or viscosity varied through indirect incidence light radiation.Direct compaction of powdered sample into the apparatus, as well as the piezoelectric element is not directly exposed to the sample in order to prevent wear and tear.In this process, the indirect transmission light energy in the sample.To avoid this has its physical and chemical properties changed during the tests for the determination of their pattern of response to the transit of thermal energy through you.As well as prevents this pattern is influenced by the optical properties of the sample, ensuring that it reflects only the formation of the material analyzed.When this pattern is compared to a reference sample, you can then determine the degree of difference between them.When this degree is greater than a certain difference, predetermined experimentally, it can be concluded that materials sampled are distinct.This type of test can be performed for certification of products such as coffee and fruit juices.The present invention applies, therefore, for quality control in production lines for surveillance, as well as to certification systems for various of products in powder and liquid.
