광섬유 온도 측정을 선택하는 방법

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, 등;

그 이상이 있을 때 30 측정 포인트, quasi 분산형 광섬유 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 킬로미터, Raman scattering distributed Raman temperature measurement can be used.

2. Measurement temperature range:

Fluorescent fiber optic temperature sensors can measure temperatures ranging from -40 °C에서 300 °씨;
The temperature measurement range of the 분산 광섬유 온도 측정 시스템: -40 ℃~120 ℃ (conventional fiber optic) -40 °C~250 °C (special fiber optic);
High temperature fiber optic grating sensor: 600 °씨 -800 °씨;

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

4. Selection of signal output interface:
The signal output is divided into analog output and digital output. There are two types of analog outputs: 0-5V/10V voltage output and 4-20mA current output. Digital outputs include RS-232; RS-485; USB; 이더넷, 등.

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 보드, 일반 데스크탑, 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.
