一种能适应恶劣环境的位置测量器件及其装置

A Kind of Displacement-measuring Device Fit for Adverse Circumstances

介绍一种采用干簧管元件和永久磁钢构成的磁性编码器及采用单片微机应用系统和磁性编码器组成的位置测量装置．该装置具有结构简单、不受温度、压力、湿度、尘埃和酸碱等腐蚀性环境的影响，寿命长、价格低、可靠性高等特点．适用于量程大、环境恶劣，但分辨率要求不高的位置检测场合．

introduced are a magnetic coder consisting of torngue switch andpermanent magnet steel, and single-chip-microcomputer system and the abovementioned coder. The device is characterized by simple structure, longer servicelife, low price and high reliability and is not influenced by temperature, pressure, humidity, dust, acidity and basicity circumstances. It is applicable to thecases of displacement measurement with wider range, and under adverse circumstances, not requiring for high discrimination.
