نحوه انتخاب اندازه گیری دمای فیبر نوری

Selection of fiber optic temperature measurement products

The fluorescent fiber optic sensing system is usually composed of three parts: a probe, a fluorescent transmission fiber, and a transmitter. When choosing a fluorescent fiber optic temperature sensing product, you need to carefully plan your selection.
After confirming that it can be used on the product you need, you can start selecting fluorescent fiber optic sensor products.

1. Select based on the number of temperature measurement points

If the total number of temperature measurement hotspots is less than 20, fluorescent fiber optic temperature sensors can be used, such as single channel fiber optic temperature measurement, fluorescent fiber optic temperature measurement devices with three, six, nine channels, و غیره;

زمانی که بیشتر از 30 نقاط اندازه گیری, quasi فیبر نوری توزیع شده temperature measurement products, such as fiber optic grating sensors, can be used;

When the temperature measurement space belongs to linear measurement and the measurement distance is relatively long, such as about 10 کیلومتر, Raman scattering distributed Raman temperature measurement can be used.

2. Measurement temperature range:

Fluorescent fiber optic temperature sensors can measure temperatures ranging from -40 ℃ به 300 ℃;
The temperature measurement range of the سیستم اندازه گیری دمای فیبر نوری توزیع شده: -40 ℃~120 ℃ (conventional fiber optic) -40 ℃~250 ℃ (special fiber optic);
High temperature fiber optic grating sensor: 600 ℃ -800 ℃;

3. Requirements for accuracy and resolution:
The usual temperature measurement accuracy is divided into five levels: ± 1 ℃;

4. انتخاب رابط خروجی سیگنال:
The signal output is divided into analog output and digital output. دو نوع خروجی آنالوگ وجود دارد: 0-5خروجی ولتاژ V/10 ولت و خروجی جریان 4-20 میلی آمپر. خروجی های دیجیتال شامل RS-232 است; RS-485; USB; اترنت, و غیره.

5. Selection of installation form:
Signal demodulators usually come in various forms, such as handheld portable and fixed, with or without a display. Fixed products include industrial standard DIN slide rail installation, PCB board, ordinary desktop, and standard industrial cabinet types. A portable demodulator can record measurement data anywhere and record the data on an internal storage medium, and then transmit the data back to the computing device when convenient.
The installation methods of probes usually include: embedding, implantation, tape binding, clip fixation, thread fixation, adhesive bonding, and other forms.

6. Choice of price point
Although various types of fiber optic sensors are still high-tech products, their prices have greatly decreased and are generally higher. Users usually need to choose between product performance/functionality and price. Choose the best cost-effective product.
