Abstract
Dispositivo para la manipulación y detección de nivel de líquidos. El dispositivo comprende una sonda integrada por un cuerpo envolvente portador interiormente de un tubo capilar de recogida de muestras así como de un cono receptor de puntas desechables acoplables y desacoplables mecánicamente, estando conectada la sonda que actúa como condensador variable, a un oscilador de baja frecuencia, combinado con un segundo oscilador de frecuencia mucho más elevada, a través de un dispositivo contador que realiza un contaje de frecuencia durante un período de ventana correspondiente a un número definido de ciclos de la frecuencia de oscilación del primer oscilador a efectos de medir con precisión la frecuencia variable del primer oscilador, pasando la señal de contaje a un microprocesador para decidir la detección de nivel, presencia de punta desechable u otras características preprogramadas.
