Abstract

Un dispositivo vibratorio para medir la amplitud de vibración de un equipo eléctrico, estando destinado dicho dispositivo a ser puesto en vibración y comprendiendo una paleta unida a dicho dispositivo o miembro vibratorio para movimiento con el mismo; un manantial de luz, un receptor de luz, estando situados dicho manantial de luz y dicho receptor de luz para transmisión de luz desde el manantial al receptor, incluyendo la paleta una parte que se extiende en la trayectoria de la luz entre el manantial y el receptor y teniendo dicha parte una pluralidad de elementos para dirigir luz al receptor y elementos de absorción de luz que se alternan entre sí y que se extienden transversalmente a la dirección de movimiento del miembro vibratorio y espaciados uniformemente en dicha dirección, una máscara estacionaria que cubre el receptor de luz y que tiene al menos un elemento de transmisión de luz del mismo tamaño y de la misma orientación que los de los elementos de dirección de luz de la paleta, ydichos medios de recepción de luz incluyen medios de contador para contar el número de ocasiones en que se produce mínima transmisión de luz a los medios de recepción de luz.
