摘要
介绍了石英挠性加速度计及倾斜传感器、水平仪的基本工作原理,分析了传统提高倾斜传感器精度的方法和措施及各自的局限性。根据倾斜传感器在0°和180°两个位置的输出特性提出了零位自标校技术,它可有效地减小零位误差,使倾斜传感器的精度在全温范围内达到20″。
Basic operation principles of crystal flexibility accelerometer, inclinometer and leveler have been sim- ply introduced. Classical methods of improving accuracy of tilt sensor have been analyzed and limitation of each method has been pointed out. Auto-zero technology based on output characteristics of tilt senor at 0° and 180° two positions has been proposed, zero error can been effectively decreased based on this technology. The accuracy of tilt sensor can reach 20＂ throughout the whole operation temperature range.
