Abstract

sensor de fluxômetro eletromagnético que pode detectar um campo magnético e uma permeabilidade magnética [001] trata-se de um sensor de fluxômetro eletromagnético que pode detectar um campo magnético e uma permeabilidade magnética e que compreende um flange (11) e um tubo de medição (12). uma bobina de referência (14) e uma bobina de excitação (13) são fixadas ao tubo de medição (12). a bobina de referência (14) e a bobina de excitação (13) são enroladas separadamente e são mantidas a uma certa distância. entre sinais da bobina de referência (14), uma proporção de sinais que reflete o fluxo medido principal aumenta para mais do que quatro vezes àquela de uma bobina de referência convencional, de tal modo que se torne possível medir um fluido com permeabilidade magnética variável, e, ainda, a estabilidade zero e a precisão de medição também são aumentadas.
