The Development Of The Optical Fiber Infrared Radiation Thermometer

With the development of science and technology, temperature measurement has been paid more and more attention, and the requirements on the measurement accuracy of the increasingly high. optical fiber infrared thermometer is a non-contact measurement instrument using optical fiber technology, compared with other types of temperature meter, it has a long distance, no contact, no sampling, non disintegration, and has the advantages of accurate, fast, intuitive etc, can be in a certain distance, quantitative, real-time temperature online detection of hot spots. According to different objects, different occasions. The product is a metallurgical smelting, forging, rolling temperature measuring instrument for machining, heat treatment, silicate, refractory material, carbon products and scientific experiments and other widely used.In this paper, the infrared radiation temperature measurement theory and the functional requirements of infrared radiation thermometer, the overall design scheme of optical fiber infrared radiation thermometer is proposed. The hardware circuit and the corresponding software module are designed. The hardware structure and software flow chart are given in the paper, and the realization method of the function module is described in this paper.In this paper, design of optical fiber infrared radiation thermometer through a third party inspection institutions of electromagnetic compatibility test, the design is verified on the hardware, software, and the rationality of the practical and reliable product performance and achieve expected goals. To expand the application of infrared temperature measurement technology field.
