Abstract

UN DISPOSITIVO Y UN METODO DE MEDIDA DE PRESION COMPRENDE COLOCAR UNA PILA PIEZOELECTRICA (16) EN UN ALOJAMIENTO ADYACENTE A LA TUBERIA EN LA QUE VA A MEDIRSE LA PRESION. EL ALOJAMIENTO CONSTA DE UN BLOQUE PRINCIPAL (11) Y UN BLOQUE SUJECION (12). LA PRESION DEL LIQUIDO EN LA TUBERIA DEFORMA A LA MISMA, DETECTANDOSE LA DEFORMACION EN LA PILA PIEZOELECTRICA (16), QUE GENERA UNA SEÑAL CORRESPONDIENTE A LA PRESION.
