温度测量仪表的分类温度测量仪表按测温方式可分为接触式和非接触式两大类。

通常来说接触式测温仪表比较简单、可靠，测量精度较高；但受耐高温材料的限制，不能应用于很高的温度测量。

非接触式仪表测温是通过热辐射原理来测量温度的，测温元件不需与被测介质接触，测温范围广，不受测温上限的限制，也不会破坏被测物体的温度场，反应速度一般也比较快；但受到物体的发射率、测量距离、烟尘和水气等外界因素的影响，其测量误差较大。

按工作原理分为膨胀式、电阻式、热电式，辐射式。

玻璃管温度计是根据液体热膨胀原理测温，双金属温度计是根据固体热膨胀原理测温，热电阻根据热阻效应原理测温，热电偶根据热电效应原理测温，辐射高温计根据热辐射原理测温。

一、热电偶热电偶是工业上最常用的温度检测元件之一。

其优点是：①测量精度高、热惯性小。

因热电偶直接与被测对象接触，不受中间介质的影响。

②测量范围广。

常用的热电偶从-50~+1600℃均可边续测量，某些特殊热电偶最低可测到-269℃（如金铁镍铬），最高可达+2800℃（如钨-铼）。

③构造简单，使用方便。

④输出信号为电信号，便于远传。

1．热电偶测温基本原理将两种不同材料的导体或半导体A和B焊接起来，构成一个闭合回路，当导体A和B的两个执着点1和2之间存在温差时，两者之间便产生电动势,因而在回路中形成一个电流,这种现象称为热电效应。

热电偶就是利用这一效应来工S、B、E、K、R、J、T七种标准化热电偶为我国统一设计型热电偶。

工业用热电偶的测温范围见下表：在使用热电偶补偿导线时必须注意型号相配，极性不能接错，补偿导线与热电偶连接端的温度不能超过100℃，B偶不用补偿导线，用普通的屏蔽线。

2、热电偶的结构一般由热电极、绝缘套管、保护管、接线盒组成。

普通型热电偶按其安装时的固定形式可分为固定螺纹连接、固定法兰连接、活动法兰连接无固定装置等多种形式。

热电极：一般金属Φ0.5~3.2mm，昂贵金属Φ0.3~0.6mm，长度与被测物质有关，一般为300~2000mm，通常在350mm左右；绝缘管：隔离热电偶与被测物，一般在室温下要5MΩ左右；保护套管：避免受被测介质的化学腐蚀和机械损伤；接线盒：固定接线座，连接补偿导线。

非接触式温度计的工作原理非接触式温度计是一种先进的测温工具，它能够在不接触测量目标物体的情况下，准确地测量物体的温度。

这种温度计广泛应用于医疗、工业生产以及家用电器等领域。

下面将详细介绍非接触式温度计的工作原理。

1. 红外线辐射测温原理：非接触式温度计通过利用物体的红外辐射来测量物体的温度。

根据斯特藩-波尔兹曼定律，这种红外辐射的强度与物体的温度成正比。

温度计接收到物体发出的红外线辐射后，经过特定的光学组件进行聚焦和收集，并转换为电信号。

2. 光电探测器：温度计内置了一种称为光电探测器的元件，它能够接收并转化光信号为电信号。

光电探测器的主要成分是半导体材料，通过与红外辐射相互作用，产生电荷并形成电流。

3. 红外传感器：非接触式温度计通常配备了一种称为红外传感器的装置，它能够探测环境中的红外辐射。

红外传感器常常是由红外探测元件和光电探测器组成。

红外辐射被物体发出后，会被红外传感器接收到。

4. 光学系统：非接触式温度计中的光学系统是至关重要的一部分。

这个系统主要包括透镜、滤光片和反射镜等。

透镜用于集中红外辐射，使其能够在红外探测元件上产生更大的信号。

滤光片的作用是选择性地通过红外辐射，并尽量阻止其他类型的光线干扰。

反射镜可将光线反射回红外传感器，提高仪器的测量精度。

5. 信号处理和显示：非接触式温度计通过信号处理和数字显示来输出温度测量结果。

信号处理部分负责对红外辐射信号进行放大、滤波和转换等处理。

经过处理后，信号被传输到数字显示屏上，以显示出物体的温度值。

非接触式温度计的工作原理可以总结为红外辐射测温原理、光电探测器、红外传感器、光学系统和信号处理及显示。

这种温度计具有测量速度快、无损伤、操作简便等优点，广泛应用于各个行业。

在医疗领域中，非接触式温度计可用于测量体表温度，如额头或耳朵温度，适用于接触传染风险较高的场合。

在工业生产过程中，非接触式温度计可用于测量高温物体或难以接触的物体的温度，为生产过程提供实时的温度监测数据。

单点温度的测量方法
单点温度的测量方法是指在一个物体或空间中，仅对一个位置的温度进行测量的方法。

这种测量方法广泛应用于工业生产、科学实验、医疗诊断等领域。

以下是常见的单点温度测量方法：
1. 接触式温度计：该方法通过将温度计的感应部分与被测物体接触，来测量该位置的温度。

常见的接触式温度计包括温度计探针、热电偶、热敏电阻等。

2. 非接触式温度计：该方法采用红外线技术，通过测量被测物体表面的辐射能量来推算出该点的温度。

常见的非接触式温度计包括红外线温度计、激光测温仪等。

3. 热成像仪：该方法利用红外线成像技术，可以同时测量多个位置的温度。

热成像仪可以将不同温度的区域呈现为不同颜色的热图，方便用户快速了解被测物体的温度分布情况。

无论采用哪种方法，单点温度测量都需要注意以下几点：
1. 测量前应保证被测物体表面干燥、清洁、无油污等干扰因素。

2. 测量时应遵循仪器的使用说明，按照标准操作流程进行，以确保测量结果的准确性。

3. 不同的温度测量方法具有不同的适用范围和精度，应根据实际需要选择合适的方法进行测量。

工业上常用的温度检测仪表分为两大类：非接触式测温仪表（如：辐射式、红外线）。

接触式测温仪表（如：膨胀式、压力式、热电偶、热电阻）。

本文将对实际工作中温度仪表出现的故障进行分析并说明处理办法，详情请看下文。

1热电阻测温计工业热电阻的常见故障是工业热电阻断路和短路。

一般断路更常见，这是因为热电阻丝较细所致。

断路和短路是很容易判断的，可用万用表的“×1Ω”档，如测得的阻值小于R0，则可能有短路的地方；若万用表指示为无穷大，则可判定电阻体已断路。

电阻体短路一般较易处理，只要不影响电阻丝长短和粗细，找到短路处进行吹干，加强绝缘即可。

电阻体断路修理必须要改变电阻丝的长短而影响电阻值，为此以更换新的电阻体为好，若采用焊接修理，焊接后要校验合格后才能使用。

热电阻测温系统在运行中常见故障及处理方法如下表：2热电偶测温计正确使用热电偶不但可以准确得到温度的数值，保证产品合格，而且还可节省热电偶的材料消耗，既节省资金又能保证产品质量。

除了补偿导线接反，用错及接线松动引起的常见误差外（处理方法：正确使用补偿导线，紧固接线端子），安装不正确，热导率和时间滞后等误差，它们是热电偶在使用中的主要误差。

2.1.安装不当引入的误差如热电偶安装的位置及插入深度不能反映炉膛的真实温度等，换句话说，热电偶不应装在太靠近门和加热的地方，插入的深度至少应为保护管直径的8～10倍；热电偶的保护套管与壁间的间隔未填绝热物质致使炉内热溢出或冷空气侵入，因此热电偶保护管和炉壁孔之间的空隙应用耐火泥或石棉绳等绝热物质堵塞以免冷热空气对流而影响测温的准确性；热电偶冷端太靠近炉体使温度超过100℃；热电偶的安装应尽可能避开强磁场和强电场，所以不应把热电偶和动力电缆线装在同一根导管内以免引入干扰造成误差；热电偶不能安装在被测介质很少流动的区域内，当用热电偶测量管内气体温度时，必须使热电偶逆着流速方向安装，而且充分与气体接触。

2.2.绝缘变差而引入的误差如热电偶绝缘了，保护管和拉线板污垢或盐渣过多致使热电偶极间与炉壁间绝缘不良，在高温下更为严重，这不仅会引起热电势的损耗而且还会引入干扰，由此引起的误差有时可达上百度。

非接触式温度传感器应用于医疗摘要——在这项研究中，我们已经开发出一种非接触式温度传感器，它使用卤化银红外光纤，用于医疗内窥镜。

我们测量的红外辐射，是通过热光纤光功率表，从热源由一银卤化物转移。

此外，一个热源和光功率测量温度之间的关系是确定的。

为了提高通过光纤银卤化物的红外辐射量和红外遥感的的一部分热光功率表，如红外线对焦镜头和光学设备准直器的使用。

热源和光功率测量温度之间的关系是确定的。

光纤温度测量范围：温度传感器采用热光功率表是从30至70摄氏度。

预计非接触式温度传感器采用红外光纤可根据本研究的结果为基础的医疗和工业应用开发。

关键词—红外光纤，光热功率计，非接触式温度传感器，红外线辐射I. 导言一般来说，非接触式温度计可以测量从一个遥远的红外辐射热源排放。

在没有明确的光纤温度传感器或一个红外光纤和红外线传感器组合许可的情况下，非接触式表面视线清楚。

这可能有助于确定了快速运动物体的表面温度，甚至在狭窄的地方和电磁场测量温度[1，2]。

作为一个红外波导，光纤的基于混合卤化银晶体，AgClxBr1 - X，被认为是为低温度下测量的最佳选择。

这些纤维的特点是灵活，不溶于水，且无毒[3]。

出于这个原因，卤化银红外光学纤维应用在红外光谱中，辐射测量和工业及医疗应用的热成像[4]。

在这项研究中，我们已经开发出一种使用卤化物红外线非接触式温度传感器，用于医疗内窥镜。

它可能会制造一个内窥镜系统，包括图像指导，光导和光纤温度传感器作为非接触式辅助通道。

通过使用热光功率表，光纤温度传感器测量的温度范围是30到70摄氏度。

II.物品和器材本次研究红外光纤选择的是卤化银红外光纤（红外900/1000，JT Ingram公司）。

这种纤维的外径为1.0毫米，包层的厚度为0.05毫米。

核心和包层的折射率是2.15和2.13，数值孔径（NA）为0.25。

银色金属卤化物的红外光学纤维是由纯氯化生产的：在一个核心包层结构的溴化银固溶体晶体。

非接触式温度计原理
非接触式温度计利用红外辐射原理来测量物体的温度，其工作原理可以简述如下：
红外辐射是一种位于可见光和微波之间的电磁波。

所有物体都会发射红外辐射，辐射强度和物体的温度成正比。

非接触式温度计利用可以感测的红外辐射来测量物体的温度。

当使用非接触式温度计时，首先需要对准目标物体。

然后，温度计会发射一束窄的红外线束或红外辐射波。

这束波会与目标物体表面的红外辐射进行相互作用。

根据斯特凡-波尔兹曼定律，辐射的强度与物体的温度是呈线性关系的。

非接触式温度计测量目标物体表面发射的红外辐射强度，然后通过一个内置的算法将其转换为相应的温度。

具体来说，温度计测量目标物体表面的红外辐射强度，然后将其转化为电信号。

该电信号经过放大、滤波和处理后，会被转换成所需的温度数值，并通过显示屏或指示灯显示出来。

非接触式温度计的优点是可以在远距离范围内测量温度，而不需要接触物体表面。

这使得它非常适用于测量高温物体、难以接触的物体、移动物体或不安全环境中的物体温度。

此外，它的测量速度快，方便易用。

然而，非接触式温度计也存在一些局限性。

首先，测量的是物体表面的温度，而非物体内部的温度。

其次，不同材料的表面
特性以及环境条件可能会对测量结果产生一定的干扰。

因此，在使用非接触式温度计时，需要根据具体情况选择合适的仪器和方法，并对测量结果进行适当的修正。
