Abstract

Inventia se refera la o metoda si la un aparat pentru masurarea umiditatii pastelor si materialelor omogene supuse operatiilor de prelucrare si formare prin presare, laminare si uscare. Metoda pentru masurarea pastelor si materialelor omogene constaîn masurarea impedantei electrice dintre electrozii de testare care sînt presati pe materialul de testat precum si a impedantei determinate de adîncimea amprentei lasata de acestia în material, transformarea acestor impedante în curenti în asa fel încît raportul celo doi curenti rezultati sa varieze între 1 si 3 însumarea apoi a cestor curenti si afisarea pe scala instrumentului indicator a umiditatii obtinuta ca functie liniara de curent total. Aparatul, conform inventiei, cuprinde un circuit deintrare a impedantei determinata de adîncimea amprentei, un bloc traductor de umiditate si adancimea maprentei, constituit din doi electrozi de testare a caror presiune asupra probei este reglata prin intermediuzl unui arc prevazut cu un piston afla t în interiorul unui cilindru legat la un tub în forma de "U", umplut cu doua lichide nemiscibile de densitati diferite.The invention relates to a method and apparatus for measuring the humidity of pastes and homogenous materials subjected to processing and forming operations by pressing, laminating and drying. The method for measuring the homogeneous pastes and materials consists in measuring the electrical impedance between the test electrodes that are pressed on the test material and the impedance determined by the depth of the fingerprint left in the material, transforming these impedances into currents such that the ratio of the two resulting streams varies between 1 and 3 then summing up currents and displaying on the scale of the humidity indicator instrument obtained as a linear function of total current. According to the invention, the apparatus comprises an impedance damping circuit determined by the depth of the fingerprint, a moisture transducer block and the depth of the map consisting of two test electrodes whose pressure on the sample is adjusted through a spring provided with a piston located inside a cylinder connected to a U-shaped tube, filled with two immiscible liquids of different densities.
