摘要 应对海洋温度高精度测量需求,结合国家温度基准水三相点和镓熔点装置对海洋用国产负温度系数(NTC)热敏电阻元件长期稳定性进行考察,通过引入等温热管技术的恒温槽并采用“瞬时比较法”对NTC热敏电阻温度计进行校准方法探索。结果表明,经过筛选的国产NTC热敏电阻元件稳定性可达到海洋领域所需水平;常规封装工艺易导致NTC热敏电阻温度计稳定性下降,进行多次热循环是提高其稳定性的有效手段;校准点数量和分布对校准水平具有较大影响;存在高性能温度计在各点校准偏差很小且几乎不受选点分布影响。研究结果有助于建立NTC热敏电阻温度计评测方法和控制标准,为海洋测温领域计量体系发展指明方向。 To meet the demand for high-precision measurement of ocean temperatures,the long-term stability of domestic Negative Temperature Coefficient(NTC)thermistor elements for ocean temperature measurement was investigated by using the national temperature reference of water triple point and gallium melting point.The calibration method for NTC thermistor thermometers was explored by introducing the thermostatic bath with the isothermal heat pipe technique and adopting the“instantaneous comparison method”.The results showed that the domestic NTC thermistor elements can have a half-year stability better than 1 mK,but long-term evaluation is still necessary.The conventional packaging processes can easily decrease the stability of NTC thermistors,and multiple thermal cycles are an effective way to improve the stability.The number and distribution of calibration points have a great influence on the calibration.But there are high-performance thermometers with little calibration deviation,hardly affected by the distribution of selected points.The analysis of these thermometers can help establish NTC thermistor evaluation standards and shed light on the development of the field of ocean temperature measurement.
