Point type fiber optic temperature measurement system

The point type Sensor suhu gentian optik converts the temperature information of the monitored area into optical signals and transmits them to the fluorescence fiber optic thermometer. The probe of the fluorescence fiber optic sensor independently developed by FJINNO is the most advanced fluorescence fiber optic thermometer in China, which can be directly installed on the measured point, with accurate temperature measurement and fast response. The point type fiber optic thermometer receives real-time optical signals carrying temperature information sent by fluorescent fiber optic temperature sensors, and demodulates them into temperature values through the principle of fluorescent fiber optic temperature measurement, achieving temperature measurement of the monitored area. The monitoring system can set an alarm signal when the actual temperature measurement value is greater than the alarm set value, and can set the temperature control device to trip and other device settings. The point type fiber optic thermometer can work independently on a single channel, or can be used in a network with multiple multi-channel fiber optic temperature sensor systems.

The point type fiber optic temperature measurement system is a distributed temperature measurement system consisting of a fluorescent fiber optic temperature sensor probe, a fiber optic temperature sensor (fiber optic temperature transmitter module), a fluorescence transmission fiber optic, a monitoring host display screen, Dll. The fiber optic temperature sensor demodulates the optical signal of the temperature information carried by the fiber optic temperature sensor probe, converts it into a temperature value, and then uploads it to the monitoring host through the fluorescence fiber optic demodulator to complete the temperature monitoring of the measured part. The fiber optic device and high-temperature resistant insulation material are used as the fiber optic temperature measurement probe, and single-mode fiber optic is used to achieve long-distance signal transmission. Special signal demodulation and filtering algorithms are used to improve the measurement accuracy and stability of the product. Low product cost, strong anti vibration and anti electromagnetic interference capabilities, ketepatan tinggi, Kelajuan tindak balas yang pantas, resolusi tinggi, unrestricted transmission distance, dan kebolehskalaan. It can be used in situations such as difficult power supply, pengedap, voltan tinggi, medan magnet yang kuat, microwave field, nuclear radiation, strict explosion-proof, kalis air, anti-karat, small spaces or small workpieces.

Application of point type fiber optic temperature sensor in high-voltage switchgear equipment

The optical fibers are routed along the corners of the cabinet and the weak current cable trough, atau diikat bersama dengan tali penebat bersama wayar sekunder di dalam kabinet. This monitoring system has comprehensive monitoring and alarm functions, ensuring that high-voltage equipment is always in a monitored state and completely unaffected by human factors. Apabila penggera berlaku, sistem mengeluarkan isyarat penggera bunyi dan cahaya yang sepadan, and the on duty personnel have sufficient time to take corresponding measures. Ini amat penting untuk mengelakkan kemalangan atau menyebabkan kebakaran.

Aplikasi teknologi pengesan gentian optik jenis titik dalam pemantauan suhu alat suis voltan tinggi dalam sistem penghantaran telah mencapai pengesanan suhu dalam talian masa nyata di titik peralatan utama (Orang hubungan, sendi kabel). Pada masa yang sama, gentian optik khas dengan tahap voltan tinggi digunakan, kerana gentian optik mempunyai ciri-ciri seperti penebat elektrik, keselamatan intrinsik, dan imuniti terhadap gangguan elektromagnet, memenuhi keperluan peralatan suis kuasa voltan tinggi untuk tahap rintangan voltan gentian optik.
