Title:
【発明の名称】改良された光フアイバ遠隔センサ
Document Type and Number:
Japanese Patent JPS61502077
Kind Code:
A
Abstract:
An optically driven, electromagnetically oscillating resonant sensor subjected to a stress force wherein the optical driving energy and the optically communicated signal generated in response to the stress force are both communicated a substantial distance along a single optical fiber (14). A portion of the supply energy (19) drives the oscillatory mechanism (20) and a portion is reflected to a frequency detector (18) by the shuttering action of the resonant element. The device may be configured so as to be electrically driven and optically sensed, optically driven and electrically sensed, or both optically driven and optically sensed for maximum retrofit versatility in past, present, and future process control systems.
