2 引用文献本规程引用下列文献 JJF 1001-1998《通用计量术语定义》 JJF 1059-1999《测量不确定度评定与表示》 使用本规程时,应注意引用上述文献的现行有效版本。 概述工作用辐射温度计(以下简称温度计)是通过检测被测目标的辐射亮度或它在不同波长下的比值(转换成电信号),非接触地实现温度测量的仪器。温度计主要由光学系统、探测器、信号处理及显示部分组成。

4 计量性能要求 4。

1 允许误差限温度计的允许误差限应符合士(a%t)的规定,其中t为测量范围的上限值或测量值,a为温度计的准确度等级,a,。以温度计的技术指标为准。对于多测量范围的温度计,不同的温度范围允许有不同的a值。

2 重复性温度计测量同一温度的重复性应符合其技术指标的要求。

5 通用技术要求 5。

1 温度计铭牌应标明制造厂名(或商标少、产品名称、型号规格、出厂编号、测量范围、出厂日期、型式批准标志及编号或制造计量器具许可证标志及编号。

2 温度计各开关按钮接触良好,开关、接线端钮应有明确标记。

3 新制造温度计的外壳、零部件有良好的表面处理,不得有锈蚀、霉斑,各部分装配应正确、可靠、无缺陷。

4 温度计的使用说明书应给出测量范围、允许误差限、重复性、工作波段、距离系数、输出信号形式、工作环境温度、响应时间、工作电压等。

2 绝缘电阻 JJG 415- 2001 当环境温度为15-35 ` C,相对湿度为4596--75% RH时,采用交流供电的温度计的电源端子与外壳之间的绝缘电阻应不小于20 MS2o 5。

3 光学系统温度计的光学系统应清洁无损伤,有瞄准系统的应瞄准清晰,瞄准标记应处于瞄准视场中心。
