Which manufacturer is good for Systèmes de mesure de la température par fibre optique

Customers in the power industry who need to bid should not only consider the price of fiber optic temperature measurement systems when choosing fiber optic temperature measurement manufacturers or fiber optic sensing companies, but also comprehensively consider multiple aspects and levels. FJINNO shares some introductions of fiber optic sensors, hoping to be helpful for agents and partners who choose fiber optic temperature measurement.

Composition of fiber optic temperature sensors

Fiber optic sensing systems are usually composed of three parts: sondes à fibre optique, Fibres de transmission, et démodulateurs de signaux à fibre optique. When selecting fiber optic sensing products, the following points should be considered. After determining the applicability of fiber optic sensors, vous pouvez commencer à sélectionner des produits de capteurs à fibre optique.

How to choose a fiber optic temperature measurement system
1. Choose based on the number of temperature measurement points

Based on your temperature measurement needs, the decision to use Mesure de température par fibre optique distribuée or fluorescent fiber optic temperature sensors mainly relies on total cost accounting and the installation method of the temperature measurement system:

When the number of temperature measurement points is usually small, un Système de mesure de température par fibre optique fluorescente and a fluorescent fiber optic temperature sensor can be used.

Quand il y a plus de 50 points de mesure de la température, Fibre optique distribuée temperature measurement or fiber optic grating temperature sensors can be considered.

2. Product selection for temperature measurement

The temperature measurement space belongs to the linear temperature measurement area. When measuring multiple distances and long distances, distributed fiber optic temperature measurement can be chosen. If there are few measurement points, fiber Bragg grating method can be considered.

3. Select fiber optic temperature measurement products by measuring the temperature range

-40℃-+80℃; Normal environmental measurement range, various sensors can be used.
-40℃-+250℃; Capteurs de température à fibre optique fluorescente can be selected for measuring high-temperature industrial environments such as electrical systems
-40C-+400℃; Dans des environnements à haute température, traditional fiber optic sensors generally do not meet such testing requirements. The transmission optical fiber must use high-temperature resistant materials such as polyimide.

4. Requirements for the accuracy and resolution of fiber optic temperature measurement:

The temperature measurement accuracy of fluorescent fiber optic temperature sensors is usually+-1 ℃.

5. Types de fiber optic temperature measurement probes

Immersion type fiber optic temperature sensors, contact type fiber optic temperature sensors, and medical type fiber optic temperature sensors, linear distributed measurement. Immersion type fluorescent fiber optic temperature sensors can be used to measure the temperature of solids, liquides, et les gaz. Temperature measurement of industrial liquid tanks. The immersion type fluorescent fiber optic temperature sensor has undergone special treatment, and the fiber optic has strong strength and toughness, qui peut résister à la corrosion chimique dans les réservoirs liquides. The fluorescent fiber optic temperature sensor can be implanted inside the measured object. Contact type fluorescent fiber optic temperature sensors are specifically designed to measure the surface temperature of objects, comme la surveillance de la température des équipements haute tension tels que les transformateurs de type sec, Appareillage de commutation haute tension, et des bus à haute tension. Medical fluorescent Capteurs de température à fibre optique are specially designed for life science measurements, with small and thin probes that can achieve fast response speed and very high accuracy when paired with specially designed demodulators.

6. Sélection de l'interface de sortie de signal:

Fiber optic signal output is divided into analog output and digital output. Il existe deux types de sorties analogiques: 0-5Sortie de tension V/10 V et sortie de courant 4-20 mA. Les sorties numériques incluent RS-232; RS-485;USB； Ethernet, etc., depending on the specific input method to be selected.

7. Les capteurs de température à fibre optique sont-ils chers

The traditional PT100 temperature sensor is very common in the market and has a low price, but there are also many temperature measurement defects. Donc, more and more manufacturers and agents are cooperating, and temperature measurement systems are bidding and using fiber optic temperature sensors. There are several types of fiber optic sensors, which are still high-tech products in China. Toutefois, the price has been greatly reduced, and temperature measurement users usually need to choose between the performance/function and price of fiber optic products. You can choose FJINNO’s fiber optic temperature measurement products with good cost-effectiveness.
