摘要
在了解光纤传感器工作原理的基础上,结合具体工程实例,通过对光纤传感器、弦式仪器和差阻式仪器性能比较分析得出光纤传感器的各项性能指标均优于弦式及差阻式仪器,特别是具有量程大、精度高的优点,与弦式、差阻式仪器相比,其灵敏度要高1～2个量级。光纤传感器还能应用于一些特殊场合,如高温、强电磁干扰等环境,因此值得广泛应用。
Based on understanding the working principle of optical fiber sensor, and taking actual concrete project example, and via the optical fiber sensor, the string type instrument and the difference anti-instrument performance comparative analysis, we obtain that each performance index of the optical fiber sensor surpasses the stling type and the difference anti-instrument; and it has big measuring range and high, precision specially; compared with the string type and difference anti-instrument, its sensitivity wants the high 1-2 magnitudes, but also can be applied to some special cases; such as in high temperature, strong electronmagefic interference; therefore it is worth applying widely.
