本文介绍了一种新型的1128型电感、电容传感器机组的轴角编码系统。该系统采用了粗精两通道,粗编码器由高精度电感移相器来完成,精编码器由电容传感器来完成。由于采用了具有反馈补偿绕组及水银液体电刷等新技术,使得系统性能大大改善。本机系统精度1.3弧秒,角分辨率0.5弧秒,数据重复性1弧秒,允许最大转速36°/秒,可以实时取样输出。通过摇摆及振动等实验表明,该系统对于较恶劣的环境,如:温度、湿度、气压、摇摆、振动、冲击的影响,适应性能良好。
This article describes a new type of 1128 inductance, capacitance sensor shaft angle coding system. The system uses a rough two-channel, coarse encoder phase shifter to complete the high-precision inductance, precision encoder by the capacitive sensor to complete. Due to the use of feedback compensation winding and mercury liquid brush and other new technologies, making the system performance greatly improved. Native system accuracy of 1.3 arc seconds, angular resolution of 0.5 arc seconds, 1 arc seconds of data repeatability, allowing the maximum speed of 36 ° / sec, real-time sampling output. Experiments show that the system is suitable for harsh environments such as temperature, humidity, air pressure, rocking, vibration and impact.
