Abstract

MANOMETRO CON CONMUTADOR INDICADOR EN DONDE UN TUBO BOURDON Y UN CONMUTADOR ELECTRICO ESTAN ALOJADOS DE FORMA ESTANCA DENTRO DE UN COMPARTIMIENTO LLENO DE LIQUIDO, ESTANDO PREVISTO UN RECORRIDO DE LIQUIDO ENTRE EL TUBO BOURDON Y UN ACCESORIO EXTERNO. LOS CONDUCTORES DEL CONMUTADOR ELECTRICO PUEDEN CONECTARSE EN EL EXTERIOR DEL COMPARTIMIENTO Y EL TUBO BOURDON ESTA CONECTADO MECANICAMENTE CON UN INDICADOR DE PRESION CON EL FIN DE PROPORCIONAR UNA LECTURA ANALOGICA DE LA PRESION REAL DENTRO DEL TUBO BOURDON, ESTANDO DICHO TUBO BOURDON CONECTADO MECANICAMENTE CON EL CONMUTADOR DE PRESION PARA PROPORCIONAR EL ACCIONAMIENTO DEL CONMUTADOR SIEMPRE QUE LA PRESION DENTRO DEL TUBO BOURDON ALCANCE UN NIVEL PREDETERMINADO.
