Which is a good manufacturer of fiber optic temperature measurement system

Customers who need to bid in the power industry 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 take into account comprehensive considerations from all aspects and levels. Fuzhou Huaguang Tianrui shares some introductions of fiber optic sensors, hoping to be helpful for agents and partners who choose fiber optic temperature measurement.

Composition of I-Fiber Optic Temperature Sensor

Fiber optic sensing systems usually consist of three parts: fiber optic probes, transmission fibers, and fiber optic signal decoders. When choosing fiber optic sensing products, the following points should be considered. Once the applicability of the fiber optic sensor is determined, you can start selecting fiber optic sensor products.

How to choose a fiber optic temperature measurement system

1. Choose the number of points for temperature measurement

Based on your temperature measurement needs, we will determine whether to use distributed fiber optic temperature sensors or fluorescent fiber optic temperature sensors, mainly relying on total cost accounting and the installation method of the temperature measurement system

When the number of temperature measurement points is usually small, a fluorescent fiber optic temperature measurement system or a fluorescent fiber optic temperature sensor can be used.

When there are more than 50 temperature measurement points, distributed fiber optic 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, distributed fiber optic temperature measurement is chosen. If there are few measurement points, fiber Bragg grating method can be considered.

3. Choose fiber optic temperature measurement products based on temperature range measurement

-40℃-+80℃; Various sensors can be used within the measurement range of ordinary environments.
-40℃-+250℃; Electrical and other high-temperature industrial environment measurement can choose fluorescent fiber temperature sensors
-40C-+400℃; In high-temperature environments, traditional fiber optic sensors generally do not meet such testing requirements. Transmission optical fibers must use high-temperature resistant materials such as polyimide.

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

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

5. Types of fiber optic temperature probes

Immersion embedded fiber optic temperature sensor, contact type fiber optic temperature sensor, and medical type fiber optic temperature sensor for linear distributed measurement. Immersion type fluorescent fiber optic temperature sensors can be used to measure the temperature of solids, liquids, and gases. Temperature measurement of industrial liquid tanks. The immersion type fluorescent fiber temperature sensor has undergone special treatment, and the fiber has strong strength and toughness, which can resist chemical corrosion in liquid tanks. The fluorescent fiber temperature sensor can be implanted inside the object being measured. Contact type fluorescent fiber optic temperature sensors are specifically designed to measure the temperature of object surfaces, such as temperature monitoring of high-voltage equipment such as dry-type transformers, high-voltage switchgear, and high-voltage busbars. The medical type fluorescent fiber optic temperature sensor is specially designed for life science measurement, with a small and thin probe that, when used in conjunction with a specially designed demodulator, can achieve fast response speed and very high accuracy.

6. Selection of signal output interface:

Fiber optic signal output is divided into analog output and digital output. Analog outputs include 0-5V/10V voltage output and 4-20mA current output, while digital outputs include RS-232; RS-485;USB； Ethernet, njll., depending on which input method needs to be selected.

7. Is the price of izinzwa zokushisa ze-fiber optic expensive

Traditional PT100 temperature sensors are very common in the market and have a low price, but they also have many temperature measurement defects. Ngakho-ke, more and more manufacturers and agents are cooperating and bidding for temperature measurement systems to use fiber optic temperature sensors. There are several types of fiber optic sensors, which are still high-tech products in China, but the price has been greatly reduced. Temperature measurement users usually need to choose between the performance/function and price of fiber optic products. You can choose FJINNO fiber optic temperature measurement products with good cost-effectiveness.
