Abstract

EL DISPOSITIVO SE UTILIZA PARA INFLUENCIAR CONTINUAMENTE UNAS CORRIENTES DE FLUIDO Y TIENE UNA PIEZA (2) CONTROLANDO LA CORRIENTE DE FLUIDO Y QUE SE AJUSTA A PARTIR DE UN ELEMENTO (2) PIEZOELECTRICO. PARA CONTROLAR LA CORRIENTE DE FLUIDO SE TIENE EN CUENTA UN CIRCUITO REGULKADOR CONECTADO A UN COMPARADOR DE VALOR NOMINAL QUE REGULA LA SEÑAL DE SALIDA DEL ELEMENTO PIEZOELECTRICO. EL ELEMENTO PIEZOELECTRICO (1) SE CONECTA CON LA PIEZA (2) DE AJUSTE PARA EVITAR MIEMBROS INTERMEDIOS ELASTICOS. PUEDEN COMPENSARSE PEQUEÑAS MODIFICACIONES DEL AJUSTE DEL DISPOSITIVO INDEPENDIENTE DE LAS MODIFICACIONES DE TEMPERATURAS Y SIN APLICACION DE MEDIDAS DE COMPENSACION COSTOSAS EN CONSTRUCCION, Y CUMPLEN EXACTAMENTE EL VALOR NOMINAL PRECALCULADO.
