An important factor affecting the operation of any mechanical unit is the vibration of its individual components. Therefore, the development of tools for the continuous monitoring of vibration loads at critical points in the design of assemblies and mechanisms can be considered one of the most promising ways of increasing the quality and reliability of the technological equipment. Contactless fiber optic sensors with external amplitude modulation of the radiation flux can be a good basis for creating built-in vibration diagnostics of a wide class of industrial facilities, from high-precision robotic systems to systems operating in conditions of strong electromagnetic interference and harsh environments. The paper analyzes the main factors affecting the accuracy of the non-contact displacement measurement of an object via a fiber-optic sensor with external modulation. The structure and the algorithm of forming the measuring data of the sensor with automatic compensation of the influence of external factors intended for measuring the amplitude of vibration in industrial conditions are described. The results of the experimental research of the accuracy of the developed sensor on shape and surface quality of the controlled object, the sensor positioning errors during installation and state of the environment in the control zone are considered. |
