摘　　要：开发了一种耐高温、高稳定性、高可靠性、质量轻的小型磁电式转速传感器。该传感器采用变磁通式结构,可以满足直升机发动机转速测量的需求。针对航空高温恶劣的测试环境,优化设计传感器结构、封装和测试系统。通过对传感器的仿真分析和高温转速测试表明,该传感器在160℃高温下能够保持高的可靠性和稳定性。A Compact type magnetoelectric rotational speed sensor with heat resistance, high stability and light weight is designed. It is the variable reluctance type structure and can meet the demand for the measurement of helicopter engine＇ s speed. Due to high temperature and harsh environment of test, its structure and sealing are optimized. The simulation and experiment results show that the sensor can still maintain high reliability and stability in the high temperature environment of 160℃.
