控制棒位置是核反应堆最重要的运行参数之一。对于一体化的低温供热堆，棒位测量传感器必须安装在压力容器内，其运行环境及结构空间比压水堆更为苛刻。传统的线圈编码电感传感器线圈数量多、结构复杂。基于理论分析，提出了组合编码方案，所用线圈大大减少。进而进行了编码原理、环境温度影响等试验研究。结果表明：组合编码电感位置传感器原理正确、结构简单、运行可靠，可望发展成２００ＭＷ核供热堆控制棒位置测量的适用传感器
Control rod position is one of the most important operating parameters of nuclear reactors. For the integrated low-temperature heating reactor, the rod position measuring sensor must be installed in the pressure vessel, its operating environment and structural space is more demanding than PWR. The traditional coil code inductance sensor coil number, complex structure. Based on the theoretical analysis, a combined coding scheme is proposed, and the coil used is greatly reduced. Then the coding principle, the impact of ambient temperature and other experimental research. The results show that the combination encoder inductive position sensor has the advantages of correct principle, simple structure and reliable operation, and is expected to develop into a suitable sensor for position control of a control rod of a 200 MW nuclear heating reactor
