摘要

为了满足煤矿井下瓦斯压力监测的需要，设计了光纤F-P (Fabry Perot)压力传感器。该传感器基于多波束干涉原理，可以测量井眼任意段的气体压力。通过实验室标定，传感器灵敏度为0.9482 nm/Kpa;温度灵敏度为0.4429 nm /℃;基本误差为±1.06% F.S.，满足煤矿井下瓦斯压力监测标准。

Design of Fiber-Optic F-P Pressure Sensor in Boreholes of Coal Mines

In order to meet the needs of gas pressure monitoring in the boreholes of coal mines, an optical fiber F-P (Fabry Perot) pressure sensor was designed. Based on the principle of multi-beam interference, the sensor can measure gas pressure in any section of the boreholes. Through laboratory calibration, the sensitivity of the sensor was 0.9482 nm/Kpa; the temperature sensitivity was 0.4429 nm / °C; and the basic error was ±1.06% F.S. All of these can meet the monitoring standards of gas pressure in the boreholes of coal mines.
