光ファイバー温度センシング技術はどのように機能しますか?-イノ

1. 光ファイバー温度センシング技術はどのように機能しますか?

FJINNO’s fiber optic temperature sensing technology works on the principle of fluorescence decay. The system sends light pulses through an optical fiber to a phosphor sensor tip installed at the measurement point. The phosphor material absorbs this light and emits fluorescence. 励起光OFF時, 蛍光は放射し続けますが、徐々に減衰します。.

The key scientific principle is that this decay time (蛍光寿命) varies precisely with temperature—higher temperatures result in shorter decay times. By accurately measuring this decay time, our system determines the exact temperature at the sensor location. This measurement principle depends only on the time characteristic, not signal intensity, making it immune to fiber bending, コネクタの損失, または光源のバリエーション.

2. What makes fiber optic sensors immune to electromagnetic interference?

フジノさん光ファイバーセンサー電磁干渉の影響を完全に受けません (EMIの) due to their all-optical design with no metallic components. The sensors consist of:

Pure quartz optical fibers that transmit light signals without using electrical conductors
Non-metallic phosphor sensing elements that operate purely on optical principles
Dielectric materials for all sensor construction including protective coverings

Unlike conventional sensors that use electrical signals (which can be disturbed by magnetic fields), 私たちの光ファイバーセンサー transmit only light signals. Even in extreme environments with high-voltage equipment, powerful electromagnetic fields, or electrical transients, the measurement remains completely unaffected. This immunity is particularly crucial in electrical equipment applications where intense magnetic fields from high currents can cause significant measurement errors in conventional sensors.

3. What is the temperature measurement range of FJINNO fiber optic sensors?

4. What is the accuracy and response time of your sensors?

フジンノ光ファイバー温度センサー offer industry-leading performance specifications:

精度: ±1°C across the entire measurement range (higher accuracy options available for specialized applications)
解決: 0.1°C allowing detection of minute temperature changes
応答時間: 未満 1 second to full reading, significantly faster than conventional temperature sensors
Measurement cycle: Typically 200-500ms per channel, enabling near real-time monitoring of multiple points

The fast response time is particularly valuable for detecting rapidly developing thermal events in electrical equipment. Unlike conventional sensors that may have significant thermal mass and slow response, 私たちの fiber optic sensors can detect temperature changes almost immediately, providing crucial early warning of developing issues.
