新型压电加速度传感器

因压电陶瓷的性能以及机械结构易受温度影响，使压电陶瓷作为敏感元件制成的加速度传感器的应用温度范围受到限制。现在其中加入温敏元件，并利用软件进行温度补偿，使其应用温度范围得以扩大。这样的传感器具有灵敏度高、耐冲击、结构简单等优点。经车辆轴承动态监测系统实际运行结果表明，可以代替人工，实现轴承检测的自动化。

A New Piezoelectric Accelerometer

Accelerometers based on piezoceramics have such features as high sensitivity, simple structure, etc. However, the performance of piezocramics and mechanical structure are easy to change with temperature. Therefore, it cannot be used in a widely temperature range. Add temperature sensor, and compensate with PIC, and the temperature rang can be wider. Using the proposed accelerometer for axletree monitoring, the driving vehicle can be more safety.
