摘要
根据多分量地震监测系统AETA的技术需求,完成一种感应式磁传感器的研制和工业化实现。通过分析电磁扰动的监测需求,确定感应式磁传感器磁棒的各项设计参数,并提出较优材料选取以及结构设计方案。磁棒的设计指标为0.1 Hz^10 k Hz,工作温度范围为-40~130℃,监测的磁场强度范围为1~1000 n T,灵敏度大于20 m V/n T@(0.1 Hz^10 k Hz)。测试结果表明,研制的磁传感器满足AETA的性能要求。该传感器已成功地投入应用,正在大区域规模化布设。
According to the multi-component seismic monitoring system＇s technology requirements, an inductive magnetic sensor is presented and the design analysis and industrial implement are discussed. According to the requirements of electromagnetic disturbance monitoring, the authors define the design parameters and propose a well-considered plan on materials choosing and architecture designing. The covered frequency range is 0.1 Hz – 10 k Hz, the temperature range is-40 – 130°C, the monitoring range of magnetic field strength is 1 – 1000 n T, and the sensitivity requirement is larger than 20 m V/n T@（0.1 Hz – 10 k Hz）. The final test shows that the performance is achieved. This sensor is applied in multi-component seismic monitoring system which is being installed widely.
