摘　　要：为了实时监控我国地浸铀矿山井场群井水位,设计了一种基于法布里-珀罗腔(F-P)腔的地浸采铀水位实时监测传感器。该传感器的腔长由电动精密位移平台和定制夹具进行控制,传感头由硅片、基座、陶瓷插芯经胶粘耦合工艺加工而成,并在内蒙古某地浸采铀矿山进行了实地验证实验。实验结果表明,该传感器的压力测量范围为0~1.5 MPa,压力灵敏度为1.68μm/MPa,线性度为0.998,实现了地浸生产井水位参数在线监测。To monitor the water level of the well field in the in-situ leaching uranium mine in real time,a real-time monitoring sensor for the water level of in-situ leaching uranium mining based on Fabry-Perot(F-P)cavity is designed.The cavity length of t he sensor is controlled by an electric precision displacement platform and a custom fixture.The sensing head is fabricated by bonding and coupling silicon wafers,bases,and ceramic ferrules.Field verification tests are conducted in a certain in-situ leaching uranium mine in Inner Mongolia.The results indicate that the sensor's pressure measurement range is 0 to 1.5 MPa,with a pressure sensitivity of 1.68滋m/MPa and linearity of 0.998,achieving online monitoring of water level parameters in production wells.
