超小型高可靠三冗余角位移传感器研制CSCD

为了满足新型运载型号工程高可靠性要求,在闭和回路中起测量及反馈作用的角位移传感器采用串、并联相结合的三冗余设计,用于伺服机构输出轴转角测量,将机械摆角信号转换为电信号输出至控制器,实现电动伺服闭环控制。超小型高可靠三冗余角位移传感器形式为三冗余旋转式电位计,但采用了两环设计,其中一环为单路,另一环为双冗余设计,将电阻环进行重叠,从结构上组成了串并联相结合的方式,在电气上可单独使用也可以并联使用。传感器采用新型电刷结构,提高了产品的环境适应性,具有较大的社会、经济效益和推广价值。

Development of Three Redundant Angular Displacement Sensor with Subminiature and High-reliability

In order to meet the high reliability requirements of the new model to launch vehicle, the angular displacement sensor is designed by using series, in parallel with three redundancy in a closed-loop used as measurement and feedback. For servo output shaft angle measurement, the mechanical angular signal is converted to electrical signal output to the controller, so as to realize electric servo closed-loop control. Three ultra-small, high-reliability redundant angular displacement sensor is in the form of three redundant rotary potentiometer, but with two-ring design, one of the rings as the single way,another ring for double redundant design, the resistance ring will be overlapped , the structure is the combination of the series and parallel, can be used alone or in parallel electrically. This sensor using new brush structure, improving the environmental adaptability of the product, has significant social, economic benefits and promotional value.
