Abstract

Dispositivo de inspección de espesor de pared que comprende: un detector de capacidad electrostática para detectar la capacidad electrostática de una parte de un objeto sometido a una inspección de espesor de pared, y una unidad aritmética y de control para registrar la capacidad electrostática detectada por el detector de capacidad electrostática y convertir la capacidad electrostática en un espesor de pared, en el que el detector de capacidad electrostática incluye una unidad sensora puesta en contacto con la superficie de una parte del objeto sometido a la inspección de espesor de pared, y un cuerpo elástico para pretensar la unidad sensora hacia la parte del objeto; la unidad sensora presenta una superficie curvada con el radio R de curvatura; y la superficie curvada está formada uniendo una lámina de electrodo realizada a partir de resina sintética que tiene cada patrón de electrodo formado sobre la misma con un sustrato de unión de tipo cinta de modo que por lo menos el patrón de electrodo de un electrodo de medición de entre el patrón de electrodo del electrodo de medición y el patrón de electrodo de un electrodo de tierra esté posicionado sobre la superficie de una parte curvada del sustrato de unión, caracterizado por que el radio R de curvatura está representado por 2 mm <= R <= 10 mm.

Éste también es el caso en la botella elíptica 10B. Las figuras 16(1), 16(2) ilustran los resultados de medición del espesor de pared para la parte extrema superior del cuerpo de la botella elíptica 10B por toda la periferia utilizando el detector de capacidad electrostática 4 provisto del sensor 5 que presenta el radio R de curvatura de 4 mm para la superficie curvada 50. En el dibujo, los errores de medición se limitan a valores lo suficientemente
5 pequeños para cualquiera de la parte de diámetro corto 13 y la parte de diámetro largo 14 de la botella elíptica 10B.
