Abstract

"SISTEMA DE CONTROLE E PERCEPçãO DE NìVEL, DE FLUIDO RESISTIVO" Um sistema de percepção de nível de fluido incluindo um elemento resistivo possuindo uma parte de extremidade superior disposta em uma parte superior de um recipiente e uma parte de extremidade inferior disposta em uma parte de inferior do recipiente. A resistência do elemento resistivo varia entre as partes superior e inferior do recipiente. Uma tira pelo menos parcialmente condutora possuindo substancialmente o mesmo comprimento que o elemento resistivo é disposta no recipiente geralmente de forma paralela e aproximadamente no mesmo nível no recipiente que o elemento resistivo. Uma fonte de sinal de entrada é acoplada ao elemento resistivo por um resistor em série.
