La celda de presi\u00f3n de empuje de cuerda vibrante mide la presi\u00f3n total de la tierra en todos los tipos de suelo.\u00a0La celda tiene forma de pala y puntiaguda en un extremo.\u00a0Un piez\u00f3metro dentro de la unidad permite la medici\u00f3n de la presi\u00f3n del agua intersticial y, por lo tanto, la derivaci\u00f3n de la presi\u00f3n efectiva.<\/p>\n
La celda est\u00e1 formada por dos l\u00e1minas de acero soldadas alrededor de la periferia, llen\u00e1ndose de aceite el estrecho espacio entre las placas.\u00a0Un transductor de presi\u00f3n de cuerda vibrante est\u00e1 conectado por un tubo de acero corto, formando un sistema hidr\u00e1ulico sellado.<\/p>\n
Se incorpora un disco de filtro poroso en la celda y se conecta a un segundo transductor de cuerda vibrante, formando juntos un piez\u00f3metro integral.\u00a0Los dos transductores de cuerda vibrante est\u00e1n montados en t\u00e1ndem detr\u00e1s de la celda en forma de pala y protegidos dentro de la tuber\u00eda de instalaci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
