Abstract

The modelling of temperature measurements using optical fiber pyrometers for different hot object sizes with new generalized integration limits is presented. The closed equations for the calculus of the radiated power that is coupled to the optical fiber for two specific scenarios are proposed. Accurate predictions of critical distance for avoiding errors in the optical fiber end location depending on fiber types and object sizes for guiding good designs are reported. A detailed model for estimating errors depending on target size and distance is provided. Two-color fiber pyrometers as a general solution are also discussed.

摘要

本文介绍了使用光纤高温计对不同尺寸热物体进行温度测量建模时采用新的广义积分限的情况。针对两种特定场景，提出了用于计算耦合到光纤的辐射功率的封闭方程。报告了根据光纤类型和物体尺寸对光纤末端位置避免误差的临界距离的准确预测，以指导良好的设计。提供了一个详细的模型，用于估计取决于目标尺寸和距离的误差。还讨论了作为通用解决方案的双色光纤高温计。
