Abstract

LA INVENCION SE REFIERE A UN APARATO PARA TRANSFERIR UN LIQUIDO CAPAZ DE REALIZAR EXACTAMENTE LA DETECCION DEL NIVEL DEL LIQUIDO UTILIZANDO UNA SONDA DE EFECTO PIPETA INCLUSO EN EL CASO DE UNA ALTA CONDUCTIVIDAD ELECTRICA DE UN FLUIDO QUE SE MUEVE EN UN CONDUCTO DE FLUJO QUE TRANSMITE LA OPERACION DE ASPIRACION Y DE DESCARGA DE UNA JERINGA (107) A LA SONDA DE EFECTO PIPETA (100. 400, 500, 600). LA SONDA TIENE UN ELECTRODO DE DETECCION DEL NIVEL DEL LIQUIDO (103, 401, 501, 601) Y UN TUBO INTERNO (102, 402, 502, 602). EL ELECTRODO DE DETECCION DEL NIVEL DEL LIQUIDO CAPAZ DE ESTAR EN CONTACTO CON UN LIQUIDO A SER ASPIRADO ESTA ELECTRICAMENTE SEPARADO DEL TUBO INTERNO LLENO CON EL FLUIDO EN MOVIMIENTO, Y AMBOS ESTAN AISLADOS POR UN MIEMBRO DE AISLAMIENTO ELECTRICO (104B, 403, 503) ENTRE ELLOS. UN CONTENEDOR (111) QUE CONTIENE EL LIQUIDO A SER ASPIRADO ESTA SUJETO MEDIANTE UN DISPOSITIVO DE SUJECION DEL CONTENEDOR (112) Y EL NIVEL DEL LIQUIDO PUEDE DETECTARSE MEDIANTE EL CAMINO EN LA CAPACITANCIA ELECTROSTATICA ENTRE EL DISPOSITIVO DE SUJECION DEL CONTENEDOR Y EL ELECTRODO DE DETECCION DEL NIVEL DEL LIQUIDO DE LA SONDA CUANDO LA SONDA SE MUEVE HACIA ABAJO. DURANTE LA ASPIRACION DEL LIQUIDO, EL TUBO INTERNO NO SE PONE EN CONTACTO CON EL LIQUIDO. EL TUBO INTERNO Y EL DISPOSITIVO DE SUJECION DEL CONTENEDOR ESTAN PUESTOS A TIERRA.
