Abstract

"APARELHO SENSOR DE CIRCUITO". Aparelho sensor de circuito para detectar veículos que viajam ao longo de uma pista de uma estrada inclui um circuito externo produzindo uma região de campo magnético com a mesma polaridade e um circuito interno dimensionado para caber dentro desta região de polaridade constante. O circuito interno provê duas regiões de polaridade oposta, de forma que campo produzido pelo circuito externo tem um efeito nulo no circuito interno. Conjunto de circuito de detecção energiza ambos os circuitos externo e interno individualmente para detecção separada de veículos que passam sobre os circuitos.
