O melhor fabricante chinês de sensores de temperatura de fibra óptica

Na área de automação industrial, the application of various sensors is very mature, including the role of fiber optic temperature sensors. Many people can also learn about it online. No entanto, customers often want to know how to choose fiber optic sensors. Let’s make a comparison and find out what is the best choice for fiber optic temperature sensors.

The importance of selecting fiber optic temperature sensors: precisão

Most fiber optic sensors have high accuracy and can meet the application needs of many fields. The fluorescence fiber temperature measurement system independently developed by FJINO has high accuracy, com uma configuração padrão de erros positivos e negativos dentro 1 grau. The temperature accuracy can be customized according to customer needs. FJINNO’s fluorescence temperature measurement technology is leading in China, and the price of its fiber temperature measurement will vary with accuracy and measurement range. No entanto, in actual products, the measurement accuracy is affected by objective factors such as the material, nível de processamento, and signal demodulator resolution of the product itself by specific manufacturers. Many brand manufacturers need to carefully consider the quality of their products when making choices.

Fiber optic sensor product selection: estabilidade

Fluorescent fiber optic temperature measurement has significant advantages in the power and rail transit industries. Accurate temperature measurement points and continuous online monitoring. One transmitter can be connected to multiple fluorescent fiber optic temperature probes, with a standard fiber length of 3 meters and a maximum distance of 20 metros. This feature undoubtedly brings great convenience to networking. O uso de tecnologia avançada também melhorou a viabilidade desta tecnologia. Geral, produtos de medição de temperatura de fibra óptica fluorescente são muito adequados para submedição multiponto. As grades de Bragg distribuídas e de fibra são especialmente projetadas para medição de temperatura em múltiplas distâncias de longa distância.

 

Qual sensor de fibra óptica é bom: nível de complexidade

O princípio dos sensores de fibra óptica fluorescentes é usar o princípio do brilho residual da fluorescência para obter tecnologia de medição de temperatura de fibra óptica. Comparado com fibra óptica distribuída sensores e redes de Bragg em fibra, é relativamente simples, então tem uma vantagem de preço.

Qual sensor de fibra óptica é bom: frequência de resposta

A frequência de resposta depende mais do projeto da rede e da velocidade de resposta do equipamento de filtragem e desmodulação. FBG requires a high-performance demodulation and demultiplexing receiver, e a capacidade de processamento do receptor muitas vezes afeta sua frequência de resposta. FP and fluorescence based methods are relatively simple, and their response frequencies can generally be guaranteed.

 

Qual sensor de fibra óptica é bom: fonte de luz

Fiber Bragg gratings have high requirements for light sources, requiring high-power broadband light sources or tunable light sources. The requirements for fluorescent light sources are much lower, as they only need to excite fluorescence.

 

Qual sensor de fibra óptica é bom: flexibility and applicability

The probes of all three are quite compact and flexible, but FBG fiber Bragg gratings are obviously limited by their complex wavelength shift detection technology.

 

Qual sensor de fibra óptica é bom: custo

When there are only a single temperature measurement point (or a few measurement points, such as less than 50 pontos de medição), fluorescent temperature measurement systems have important advantages due to their low complexity and low requirements for light sources. Fluorescent is the most cost-effective option. No entanto, for systems with large temperature measurement points exceeding 50, distributed optical fibers and fiber Bragg gratings are more suitable.

Resumindo, it is generally believed that fiber Bragg grating sensors are suitable for large, complexo, and high-precision low-temperature distributed sensing networks. The advantages of fluorescent temperature measurement, such as fast response frequency, tamanho pequeno da sonda, and long light source life, make it suitable for flexible, pequeno, and simple sensing systems. Fluorescent methods have the advantages of high temperature measurement and low cost.
