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, امیدواریم برای نمایندگان و شرکای که اندازه گیری دمای فیبر نوری را انتخاب می کنند مفید باشد.

ترکیب از سنسور دمای فیبر نوری

Fiber optic sensing systems usually consist of three parts: پروب های فیبر نوری, فیبرهای انتقال, and fiber optic signal decoders. When choosing fiber optic sensing products, نکات زیر باید در نظر گرفته شود. Once the applicability of the fiber optic sensor is determined, می توانید شروع به انتخاب محصولات حسگر فیبر نوری کنید.

How to choose a سیستم اندازه گیری دمای فیبر نوری

1. Choose the number of points for temperature measurement

بر اساس نیازهای اندازه گیری دما شما, we will determine whether to use فیبر نوری توزیع شده temperature sensors or fluorescent fiber optic temperature sensors, mainly relying on total cost accounting and the installation method of the temperature measurement system

زمانی که تعداد نقاط اندازه گیری دما معمولا کم است, a fluorescent fiber optic temperature measurement system or a fluorescent fiber optic temperature sensor can be used.

زمانی که بیشتر از 50 نقاط اندازه گیری دما, distributed fiber optic temperature measurement or fiber optic grating temperature sensors can be considered.

2. انتخاب محصول برای اندازه گیری دما

فضای اندازه گیری دما متعلق به منطقه اندازه گیری دما خطی است. When measuring multiple distances, distributed fiber optic temperature measurement is chosen. اگر نقاط اندازه گیری کمی وجود دارد, روش رنده الیاف براگ را می توان در نظر گرفت.

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℃; در محیط های با دمای بالا, 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, مایعات, 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, تابلو برق فشار قوی, 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. انتخاب رابط خروجی سیگنال:

خروجی سیگنال فیبر نوری به دو دسته خروجی آنالوگ و خروجی دیجیتال تقسیم می شود. Analog outputs include 0-5V/10V voltage output and 4-20mA current output, while digital outputs include RS-232; RS-485;USB； اترنت, و غیره, depending on which input method needs to be selected.

7. Is the price of سنسورهای دمای فیبر نوری گران قیمت

Traditional PT100 temperature sensors are very common in the market and have a low price, but they also have many temperature measurement defects. بنابراین, more and more manufacturers and agents are cooperating and bidding for temperature measurement systems to use fiber optic temperature sensors. انواع مختلفی از سنسورهای فیبر نوری وجود دارد, که هنوز محصولات با تکنولوژی بالا در چین هستند, 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.
