APPARATUS FOR DECREPITOMETRIC SURVEYS BY MEASURING ACOUSTICAL VIBRATIONS

摘要

apparatus for decrepitofonice united, consisting of a probe block and a termoacustica signal amplification and incorporation, characterized by that,in order to reduce energy consumption and use in electric field, the probe is made up of a termoacustica casing provided with cooling profiles.fonoabsorbant fixed on a support material, at the upper casing is provided with an alcohol burner, a cloak of protectionin this burner being willing a vat of copper for the analyzed contemplated at the inferior with a steel rod guided through supports what it rests via a palpatora piezoelectric transducer attached through a mintura inside the support.
