位置传感技术研究进展

物体的准确定位是实现工业自动化生产的前提,现已经有多种位置测量方法,并已经成功地应用到了实际中。基于传统理论的位置传感器主要有电容式、电感式、电磁式等几种,这些传感器还需进一步改进,以克服测量精度低、线性度差等缺点。此外,还开发出了一些新型位置传感器,以适应特殊的需求。位移传感器同其他传感器一样,在工业自动化中越来越突现出其重要作用,同时,也对位移传感器提出了更高的要求。

Research development of position sensor technique

Moving object orientation is very useful in industry and automation. Many methods have been put forward for orientation. Position sensors based on traditional theory such as capacitance, inductance, electromagnetism and so on are developed, but they also need to improve for measuring precision and linearity. Some new type position sensors are put forward for special requirement. Position sensor is the same as other sensors, and important effect has been unfolded in industry automation. It is a challenge to position sensor.
