Abstract

Se revela un sensor de captacion capacitivo para un dispositivo de rnedicion de flujo másico. El dispositivo de medicion de flujo másico incluye un tubo sensor de flujo y un dispositivo de accionamiento para hacer vibrar el tubo sensor de flujo El sensor de captacion capacitivo incluye al menos una placa conductora conectable a un primer potencial de tension y que se adapta para que se situe adyacente al tubo sensor de flujo que está conectado a un segundo potencial de tension. La placa conductora se dispone en relacion al tubo sensor de flujo, de forma tal de definir un huelgo entre ellos. La capacitancia entre la placa conductora y el tubo sensor de flujo varía conforme al movimiento relativo de la placa conductora y el tubo sensor de flujo cuando vibra el tubo sensor de flujo. En otros aspectos de la presente, el tubo sensor de flujo está situado en un alojamiento y el dispositivo de accionamiento está posicionado fuera del alojamiento para hacer vibrar el tubo sensor de flujo.
