The high and low temperature test chamber can provide thecorresponding high and low temperature environment for instruments andmaterials, and its temperature field performance and measurementuncertainty are important indicators that affect the measurement resultsof the temperature test chamber. Through the uncertainty evaluation andinfluence analysis of temperature deviation calibration results, themeasurement performance of high and low temperature test chamber, errorsources and methods to reduce the influence of error are furtherunderstood. According to the calibration method specified in GB/T10592-2023 Technical Conditions for High and Low Temperature TestChamber, select the temperature sensor that meets the measurementrequirements and calibrate the temperature deviation of the high and lowtemperature test chamber. The calibration confirms that the temperaturefield performance of the high and low temperature test chamber meets thetolerance requirement of temperature deviation $\pm {2}^{\circ }\mathrm{C}$ , and themeasurement uncertainty meets the technical index requirement of $1/3$ maximum allowable error. Thetemperature field performance of the high-low test chamber is good, andthe short-branch A-class platinum thermal resistance selected by themeasurement standard meets the calibration requirements and has goodstability.

The high and low temperature test chamber can provide thecorresponding high and low temperature environment for instruments andmaterials, and its temperature field performance and measurementuncertainty are important indicators that affect the measurement resultsof the temperature test chamber.

高低温试验箱可用于大多数行业的温度计量以及各种材料的试验中, 电力行业的热工、电测、材料等方面能够实现测量的准确与便捷, 确保仪器仪表量值的准确与统一, 对试验箱实际应用提供数据参考 [ 1 - 2 ]
高低温试验箱温度范围可达 $-{65}^{\circ }\mathrm{C}$${200}^{\circ }\mathrm{C}$ ,其精度高、 操作简单、稳定性好、温场均匀性好, 满足大多数电工、电子及其他产品、零部件、材料进行高温或低温试验, 以及高低温循环试验的需求 [ 3 ] 。为了正确模拟产品环境温度条件就必须保证试验箱的温度场温度偏差等 技术指标符合产品温度试验标准的要求。
以下依据 GB/T 10592-2023《高低温试验箱技术条件》对其温度偏差 [ 4 ] 的校准结果及其测量不确定度进行分析和评定,就评定方法中的数学建模、不确定度分析 [ 5 ] 与计算等进行论述。
校准高低温试验箱的标准器选取为铂热电阻温度传感器, 电测设备为数字多用表, 测量系统如 图 1 所示:
被校高低温试验箱温度偏差校准根据试验箱测量范围 [ 6 ] 及使用范围, 所用传感器为铂热电阻 Pt100, 测量范围选取 $-{40}\sim {100}^{\circ }\mathrm{C}$
$\mathrm{A}$ 级工业铂热电阻作为测量标准器 [ 7 ] ,采用直接测量法, 对工作室容积不大于 $2{\mathrm{\;m}}^{3}$ 的温度试验箱进行校准。在试验箱工作室内定出上、中、下三个水平测试面, 简称上、中、下层。 上层与工作室的顶面的距离是工作室高度的 $1/{10}$ ,中层通过工作室几何中心,下层在最低层样品架上方 ${10}\mathrm{\;{mm}}$ 处。测试点位于三个测试面上, 中心测试点位于工作室几何中心, 其余测试点到工作室壁的距离为各自边长的 $1/{10}$ ,但对于工作室容积不大于 $1{\mathrm{\;m}}^{3}$ 的试验箱,该距离不小于 ${50}\mathrm{\;{mm}}$ ,工作室容积不大于
$2{\mathrm{\;m}}^{3}$ 的试验箱,测试点为 9 个,布放位置如 图 2 所示:
将工业铂热电阻置于试验箱工作室定好 9 个测试点位置处, 将试验箱传感器引线出口处按要求封堵好, 防止外界环境对试验箱温场的干扰 [ 8 ]
按照试验箱操作要求设定试验箱温场测试时的校准温度点 [ 9 ] , 当温度达到设定点温度并稳定 $2\mathrm{\;h}$ [ 10 ] ,确认试验箱温度场相对稳定后,在 ${30}\mathrm{\;{min}}$ 内每 $1\mathrm{\;{min}}$ 依次读取各测试点的温度传感器的输出值 1 次, 如此每个测试点共测量 30 次, 对测得的数据按要求进行计算。
校准高低温试验箱的数学模型 [ 11 ] 如式:
${\Delta T}= \overline{{T}_{i}}- \overline{{T}_{0}}$
其中:
$\overline{{T}_{i}}= T +\frac{\overline{{R}_{i}}- R}{\mathrm{\;d}R/\mathrm{d}t}$
$\overline{{T}_{0}}= T +\frac{\overline{{R}_{0}}- R}{\mathrm{\;d}R/\mathrm{d}t}$
则式 (1) 变为式 (4):
${\Delta T}= \frac{\overline{{R}_{i}}- R}{\mathrm{\;d}R}- \frac{\overline{{R}_{0}}- R}{\mathrm{\;d}R/\mathrm{d}t}$
整理后变为式 (5)
${\Delta T}= \frac{\overline{{R}_{i}}- \overline{{R}_{0}}}{\mathrm{d}R/\mathrm{d}t}$
式中:
${\Delta T}$ 一温度偏差, ${}^{\circ }\mathrm{C}$ ;
$T$ 一设定点温度, ${}^{\circ }\mathrm{C}$ ;
$\overline{{T}_{0}}$ 一工作空间中心点的温度平均值, ${}^{\circ }\mathrm{C}$ ;
$\overline{{T}_{i}}$ 一工作空间其他点的温度平均值, ${}^{\circ }\mathrm{C}$ ;
$R$ 一铂热电阻标称电阻值, $\Omega$ ;
$\overline{{R}_{0}}$ 一铂热电阻测得的工作空间中心点的电阻平均值, $\Omega$ ;
$\overline{{R}_{i}}$ 一铂热电阻测得的工作空间其他点的电阻平均值, $\Omega$ ;
$\frac{dR}{dt}$ 一铂热电阻在设定温度电阻值对温度的变化率, $\Omega /{}^{\circ }\mathrm{C}$ ( 查询分度表得出 )。
根据不确定度传播率通用公式, 合成标准不确定度为:
${u}_{\mathrm{c}}\left({\Delta T}\right)= \sqrt{\mathop{\sum }\limits_{{i = 1}}^{N}{\left(\frac{\partial f}{\partial {x}_{i}}\right)}^{2}{u}^{2}\left({x}_{i}\right)+ 2\mathop{\sum }\limits_{{i = 1}}^{{N = 1}}\mathop{\sum }\limits_{{j = i + 1}}^{N}\frac{\partial f}{\partial {x}_{i}}\frac{\partial f}{\partial {x}_{j}}u\left({{x}_{i},{x}_{j}}\right)} $
由于各输入量之间相互独立, 得到合成标准不确定度:
${u}_{c}\left({\Delta T}\right)= \sqrt{\mathop{\sum }\limits_{{i = 1}}^{N}{c}_{i}^{2}{u}^{2}\left({x}_{i}\right)} $
式中:
${u}_{c}\left({\Delta T}\right)$ 一合成标准不确定度;
$u\left({x}_{i}\right)$ 一输入量 ${x}_{i}$ 的标准不确定度;
$\frac{\partial f}{\partial {x}_{i}}$ 一被测量量与有关的输入量之间的函数对于输入量 ${x}_{i}$ 的偏导数;
$u\left({{x}_{i},{x}_{j}}\right)$ 一输入量 ${x}_{i}$${x}_{j}$ 的协方差。
由数学模型可得, 高低温试验箱温度偏差校准结果相关的标准不确定度 [ 12 ] 包括以下几项:
(1)工作空间中心点温度测量重复性引入的标准不确定度, ${u}_{1};\Omega$ ; ( $\mathrm{A}$ 类评定)
(2)工作空间其他点温度测量重复性引入的标准不确定度, ${u}_{2};\Omega ;\left({\mathrm{B}\text{ 类评定 }}\right)$
(3)A 级铂热电阻引入的标准不确定度, ${u}_{3};\Omega ;\left({\mathrm{B}\text{ 类评定 }}\right)$
(4)数字多用表对工作空间中心点铂热电阻引入的标准不确定度, ${u}_{4};{}^{\circ }\mathrm{C}$ ; ( $\mathrm{B}$ 类评定)
(5)数字多用表对工作空间其他点铂热电阻引入的标准不确定度, ${u}_{5};{}^{\circ }\mathrm{C}$ ; ( $\mathrm{B}$ 类评定)
利用公式 (1)、公式 (5) 对各影响量求偏导得到各标准不确定度的灵敏系数:
${c}_{1}= \frac{\mathrm{d}{\Delta T}}{\mathrm{\;d}\overline{{R}_{0}}}= \frac{-1}{\mathrm{\;d}R/\mathrm{d}t};\;{c}_{2}= \frac{\mathrm{d}{\Delta T}}{\mathrm{\;d}\overline{{R}_{i}}}= \frac{1}{\mathrm{\;d}R/\mathrm{d}t};\;{c}_{3}= 1 \\{c}_{4}= \frac{\mathrm{d}{\Delta T}}{\mathrm{\;d}\overline{{R}_{0}}}= \frac{-1}{\mathrm{\;d}R/\mathrm{d}t};\;{c}_{5}= \frac{\mathrm{d}{\Delta T}}{\mathrm{\;d}\overline{{R}_{i}}}= \frac{1}{\mathrm{\;d}R/\mathrm{d}t}$
根据公式 (8),得到合成标准不确定度 ${u}_{c}\left({\Delta T}\right)$ 的表达式为:
${u}_{c}\left({\Delta T}\right)= \sqrt{{c}_{1}^{2}{u}_{1}^{2}+ {c}_{2}^{2}{u}_{2}^{2}+ {c}_{3}^{2}{u}_{3}^{2}+ {c}_{4}^{2}{u}_{4}^{2}+ {c}_{5}^{2}{u}_{5}^{2}}$
代入公式 (9), 整理得到:
${u}_{c}\left({\Delta T}\right)= \sqrt{{\left(\frac{-1}{\mathrm{\;d}R}\right)}^{2}{u}_{1}^{2}+ {\left(\frac{1}{\mathrm{\;d}R}\right)}^{2}{u}_{2}^{2}+ {u}_{3}^{2}+ {\left(\frac{-1}{\mathrm{\;d}R\mathrm{\;d}t}\right)}^{2}{u}_{4}^{2}+ {\left(\frac{1}{\mathrm{\;d}R\mathrm{\;d}t}\right)}^{2}{u}_{5}^{2}}$
进行重复性试验时,当温度达到设定点温度并稳定 $2\mathrm{\;h}$ 后, 在 ${30}\mathrm{\;{min}}$ 内每 $1\mathrm{\;{min}}$ 依次读取各测试点的电阻输出值 1 次,共测量 30 次。
$-{40}\sim {100}^{\circ }\mathrm{C}$ 测量范围内,对校准点 $-{40}^{\circ }\mathrm{C}\text{、}{60}^{\circ }\mathrm{C}\text{、}{100}^{\circ }\mathrm{C}$ 按照要求进行重复测量,在 ${30}\mathrm{\;{min}}$ 内读取的 30 个数据作为重复性测量数据, 各测点位置的算术平均值见 表 1
由重复性引入的标准不确定度采用贝塞尔公式计算 [ 14 ] ,实验标准偏差 $s$ 计算见下式:
$ s =\sqrt{\frac{\mathop{\sum }\limits_{{i = 1}}^{n}{\left({T}_{i}- \bar{T}\right)}^{2}}{\left( n - 1\right)}}$
式中:
$s$ 一校准结果的实验标准偏差,单位: $\Omega$ ;
${x}_{i}$ 一第 $i$ 次校准结果,单位: $\Omega$ ;
$\bar{x}- n$ 次校准结果的算术平均值,单位: $\Omega$ ;
$n$ 一校准次数,取 $n ={30}$
3.2.1 工作空间中心点温度测量重复性引入的标准不确定度 ${u}_{1}$
${u}_{1}= s \\{c}_{1}= - 1/\left({\mathrm{d}R/\mathrm{d}t}\right)$
表 2 所示:
3.2.2 工作空间其他点温度测量重复性引入的标准不确定度 ${u}_{2}$
${c}_{2}= 1/\left({\mathrm{d}R/\mathrm{d}t}\right)$
表 3 所示:
根据相应的影响量对高低温试验箱温度偏差进行 $\mathrm{B}$ 类不确定度分析 [ 15 ] ,试验箱温度偏差的性能判定是在空载情况下进行实验性性能评判及不确定度分析 [ 16 ] 。具体 $\mathrm{B}$ 类不确定度分析如下。
工业铂热电阻在各校准点的测量不确定度为 ${U}_{3},{k}_{3}= 2$ ,即区间半宽 ${a}_{3}$ ,则标准不确定度按下式计算,计算结果见 表 4
${u}_{3}= \frac{{U}_{3}}{{k}_{3}}$
表 4
数字多用表在工业铂热电阻电阻测量时使用的直流电阻量程及最大允许误差为: ${100\Omega }$ 档: $\pm ({0.010}\%\times$ 读数+0.004% $\times$ 量程 ) $\Omega ,{1000\Omega }$ 档: $\pm \left({{0.010}\%\times \text{读数}+ {0.001}\%\times }\right.$ 量程 ) $\Omega$ ,区间半宽 ${a}_{4}$ 取最大允许误差绝对值,按均匀分布对待,取 ${k}_{4}= \sqrt{3}$ , 则标准不确定度按下式计算,计算结果见 表 5
${u}_{4}= {a}_{4}/{k}_{4}\\{c}_{4}= - 1/\left({\mathrm{d}R/{dt}}\right)$
表 5
3.3.3 数字多用表对工作空间其他点铂热电阻引入的标准不确定度 ${u}_{5}$
数字多用表在工业铂热电阻电阻测量时使用的直流电阻量程及最大允许误差为: ${100\Omega }$ 档: $\pm \left({{0.010}\%\times \text{读数}+ {0.004}\%\times }\right.$ 量程 ) $\Omega ,{1000\Omega }$ 档: $\pm \left({{0.010}\%\times \text{ 读数 }+ {0.001}\%\times }\right.$ 量程 ) $\Omega$ ,区间半宽 ${a}_{5}$ 取最大允许误差绝对值,按均匀分布对待,取 ${k}_{5}= \sqrt{3}$ , 则标准不确定度按下式计算,计算结果见 表 6
${u}_{5}= {a}_{5}/{k}_{5}\\{c}_{5}= 1/\left({\mathrm{d}R/{dt}}\right)$
表 6
根据不确定度传播律, 由于各标准不确定度分量彼此独立, 互不相关, 其合成标准不确定度如下:
${u}_{c}\left({\Delta T}\right)= \sqrt{{c}_{1}^{2}{u}_{1}^{2}+ {c}_{2}^{2}{u}_{2}^{2}+ {c}_{3}^{2}{u}_{3}^{2}+ {c}_{4}^{2}{u}_{4}^{2}+ {c}_{5}^{2}{u}_{5}^{2}}$
代入各标准不确定度分量,得到合成标准不确定度:
${u}_{c}{\left(\Delta T\right)}_{40}= {0.0434}^{\circ }\mathrm{C};{u}_{c}{\left(\Delta T\right)}_{60}= {0.0522}^{\circ }\mathrm{C};{u}_{c}{\left(\Delta T\right)}_{100}= {0.0749}^{\circ }\mathrm{C}$
高低温试验箱温度偏差的扩展不确定度表示为 $U ={u}_{c}\left({\Delta T}\right)\times k$ $\left({k = 2}\right)$ ,计算结果如下:
$U\left({-{40}}\right)= {0.087}^{\circ }\mathrm{C};U\left({60}\right)= {0.104}^{\circ }\mathrm{C};U\left({100}\right)= {0.150}^{\circ }\mathrm{C}$
被校高低温试验箱偏差校准结果和测量不确定度表述见下 表 7 :
通过对高低温试验箱测量方法控制及测量系统的确认, 高低温试验箱温度场性能校准结果满足温度偏差 $\pm {2}^{\circ }\mathrm{C}$ 的允差要求,测量不确定度结果满足 $1/3$ 最大允许误差的技术指标要求。 参考国标在校准过程中通过实际对试验箱工作室各位置点的布置,工作室上下层的测温元件端部与工作室壁距离 ${50}\mathrm{\;{mm}}$ 位置为最佳温度场性能符合要求的最大位置点, 校准结果得到高低试验箱校准温度场性能良好,测量标准器选取短支 $\mathrm{A}$ 级铂热电阻满足校准要求且稳定性良好符合长时间交替温度的测量使用。 高低温试验箱温度偏差的准确测量和合理评定保证了其测量的可靠性 [ 17 ] ,为其在实验室精密测量以及有特殊需求设备的现场检测工作 [ 18 ] 提供了相应的参考价值,为被试设备及材料提供准确的温度场量值。
