Карактеристики на Fiber Optic Temperature Measurement Technology

Fiber optic temperature measurement technology is a new temperature measurement technology developed in recent years, and has demonstrated many characteristics that are different from other temperature measurement methods in multiple monitoring locations. Сепак, users who require fiber optic temperature measurement systems should understand that fiber optic temperature measurement systems have similarities with other newly developed technologies. Fiber optic temperature measurement technology is not a universal temperature measurement technology, and its main purpose is not to replace traditional temperature measurement methods, but to supplement and improve traditional platinum resistance temperature measurement methods. Fiber optic can fully utilize its optical properties and develop new temperature measurement solutions, which are suitable for technical applications in different environmental fields.

Application Fields of Fiber Optic Temperature Measurement Technology

Application of fiber optic temperature measurement in temperature measurement under strong electromagnetic field.

High frequency and microwave heating methods are being applied in various fields of electromagnetic fields and are expanding into more diverse areas: high-frequency metal melting, welding and quenching, rubber vulcanization, drying of wood and fabrics, as well as pharmaceuticals, chemicals, and even microwave cooking. Fiber optic temperature measurement technology has great advantages in these different temperature measurement fields, because fiber optic does not have additional temperature rise caused by conductive parts and is not affected by electromagnetic field interference.

Temperature measurement of high-voltage electrical appliances. Fiber optic temperature sensors can be used for temperature measurement of winding hotspots in high-voltage transformers. Enable high-voltage transformers to operate safely under overload, ensuring that the high-voltage power system is in a good power distribution state. Fiber optic temperature measurement can be applied to various high-voltage devices, such as generators, high-voltage switches, and overload protection devices.

The fiber optic temperature measurement system can be applied to overhead power lines, cables under comprehensive pipe galleries, as well as temperature measurement in the production process of flammable and explosive materials, and fiber optic temperature measurement of different equipment. Fiber optic sensors are essentially fire-resistant and explosion-proof components. Fiber optic sensors do not require explosion-proof measures and have great safety and reliability. Compared with electrical sensors, it can greatly reduce costs and improve the sensitivity of temperature measurement. For example, the reaction tanks in large chemical plants work under high temperature and pressure conditions. The real-time monitoring of the surface temperature characteristics of the reaction tanks by the fiber optic temperature measurement system can ensure their correct operation. By laying the fiber optic cables along the surface of the reaction tanks into a temperature sensing grid, any hot spots generated by the reaction tanks can be monitored in a timely manner, effectively preventing accidents caused by temperature rise.

Temperature measurement of high-temperature media. Bridge safety inspection. Huaguang Tianrui can use fiber optic grating sensors in the temperature safety detection project of the bridge. Fiber optic sensors can detect the stress-strain and temperature changes of the bridge under various conditions. Fiber Bragg grating strain sensors and fiber Bragg grating temperature sensors are installed on the selected end faces of the bridge to achieve centralized management of the bridge. From the test results, it can be seen that the temperature measurement data obtained by the fiber optic sensor is consistent with the actual results.
