摘要：针对在工件尺寸测量精度要求较低的应用场景中，使用电感式笔式传感器成本偏高、操作不方便等原因，本文设计一款柱式容栅传感器。该柱式传感器基于容栅技术，通过对该传感器进行独特的柱式结构设计及基本硬件设计，使其能够实现工件尺寸的测量。本文设计的柱式容栅传感器采用RS485接口，可与大部分工控设备通信，其精度较高（0.01mm），尺寸较小（直径20mm），可尽可能多地布置于生产工件表面，实现多点以及多路测量，能够很好地满足中低端市场应用需求。

Abstract: In view of the high cost and inconvenient operation of the inductive pen sensor in the application scene with low accuracy of workpiece size measurement, a columnar capacitive grating sensor is designed in this paper. The column type sensor based on the capacitive technology, through the unique column structure design and basic hardware design of the sensor, it can measure the size of the workpiece. The columnar capacitive grating sensor in this paper adopts RS485 interface, which can communicate with most industrial control equipment; it has high precision (0.01mm) and small size (diameter 20mm), and can be arranged on the surface of the production workpiece as much as possible to realize multi-point and multi-channel measurement, which can well meet the application needs of the middle and low-end market.
Key words: capacitive technology; column type; sensor
