In the field of industrial automation, the application of various sensors is very mature, including the role of fiber optic temperature sensors. Many people can also learn about it online. Gayunpaman, 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: accuracy

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, with a standard configuration of positive and negative errors within 1 degree. 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. Gayunpaman, in actual products, the measurement accuracy is affected by objective factors such as the material, processing level, 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: stability

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 meters. This feature undoubtedly brings great convenience to networking. The use of advanced technology has also improved the feasibility of this technology. Overall, fluorescent fiber optic temperature measurement products are very suitable for multi-point sub measurement. Distributed and fiber Bragg gratings are particularly designed for temperature measurement over multiple long-distance distances.

 

Which fiber optic sensor is good: complexity level

The principle of fluorescent fiber optic sensors is to use the principle of fluorescence afterglow to achieve fiber optic temperature measurement technology. Compared with distributed fiber optic sensors and fiber Bragg gratings, it is relatively simple, so it has a price advantage.

Which fiber optic sensor is good: response frequency

The response frequency depends more on the design of the network and the response speed of the filtering and demodulation equipment. FBG requires a high-performance demodulation and demultiplexing receiver, and the processing capability of the receiver often affects its response frequency. FP and fluorescence based methods are relatively simple, and their response frequencies can generally be guaranteed.

 

Which fiber optic sensor is good: light source

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.

 

Which fiber optic sensor is good: 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.

 

Which fiber optic sensor is good: cost

When there are only a single temperature measurement point (or a few measurement points, such as less than 50 measurement points), 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. Gayunpaman, for systems with large temperature measurement points exceeding 50, distributed optical fibers and fiber Bragg gratings are more suitable.

In summary, it is generally believed that fiber Bragg grating sensors are suitable for large, complex, and high-precision low-temperature distributed sensing networks. The advantages of fluorescent temperature measurement, such as fast response frequency, small probe size, and long light source life, make it suitable for flexible, small, and simple sensing systems. Fluorescent methods have the advantages of high temperature measurement and low cost.
