一、前言传感器按系统类别可分为开环和闭环传感器。本传感器属于闭环传感器,利用力平衡原理测量过载参数。利用平衡原理是提高传感器精度的重要技术措施。用于惯导系统的加速度计大部分都采用这种原理,但这些加速度计为了千方百计提高精度一般都相当复杂,成本高,因此不宜作为测量用的传感器。本传感器从遥测本身要求出发,简化了力平衡系统的结构,满足了航天对高精度遥测小量程过载参数的需要。
First, foreword The sensor can be divided according to the system type open-loop and closed-loop sensor. The sensor is a closed-loop sensor, the use of force balance principle of measuring overload parameters. The use of balance principle is to improve the accuracy of the sensor an important technical measure. Accelerometers used in inertial navigation systems are mostly based on this principle, but these accelerometers are generally notoriously complicated to measure and cost as much as possible to improve accuracy. Based on the requirements of the telemetry itself, the sensor simplifies the structure of the force balance system and meets the aerospace’s need for high-precision telemetry with small range overload parameters.
