Abstract
UNA LINEA DETECTORA DE FILTRACION DE LIQUIDOS PARA DETECTAR CUALQUIER FUGA DE UN LIQUIDO TAL COMO ACIDO SULFURICO O ALCALI FUERTE DE UNA TUBERIA DE TRANSPORTE A UNA TANQUE DE ALMACENAMIENTO, COMPRENDE UN PAR DE ELECTRODOS ESTIRADOS, CADA UNO DE LOS CUALES CONTIENE UN CONDUCTOR (2) CUBIERTO CON UNA CAPA AISLANTE (4) HECHA DE UN MATERIAL MACROMOLECULAR QUE CONTIENE UN ENLACE ESTER, ESTANDO DISPUESTOS LOS ELECTRODOS SUSTANCIALMENTE EN PARALELO, Y UN MATERIAL (3) ABSORBENTE DEL LIQUIDO CUBRIENDO ESTOS ELECTRODOS. EL MATERIAL ABSORBENTE DEL LIQUIDO (3) PUEDE SER UN CUERPO TRENZADO HECHO DE UN HILO ABSORBENTE DEL LIQUIDO QUE ESTA COLOCADO FUERA DEL PAR DE ELECTRODOS ESTIRADOS, O PUEDE SER UNA CAPA DE CUERPO TRENZADO COLOCADA EN LA PERIFERIA EXTERIOR DE CADA UNO DE LOS ELECTRODOS. SI FUGA ACIDO SULFURICO O ALCALI LIQUIDO, EL MATERIAL ABSORBENTE DE LIQUIDO (3) QUE CUBRE LOS ELECTRODOS ABSORBE TAL LIQUIDO FILTRADO, LO QUE HACE QUE LAS CAPAS AISLANTES DISUELVAN HASTA CORTOCIRCUITAR LOS ELECTRODOS (2). LA RESISTENCIA DE AISLANTE ENTRE LOS CONDUCTORES (2) SE MIDE DESDE UN EXTREMO DE LA LINEA DETECTORA. SE DETECTA LA DISMINUCION EN LA RESISTENCIA DE AISLAMIENTO RESULTANTE.
