热敏电阻器
许多热敏电阻具有负温度系数(NTC),也就是说温度下 降时它的电阻值会升高。在所有被动式温度传感器中, 热敏电阻的灵敏度(即温度每变化一度时电阻的变化)最高, 但热敏电阻的电阻/温度曲线是非线性的。

NTC热敏电阻、温度传感器产品选型方法与应用.

NTC热敏电阻/温度传感器产品选型方法与应用NTC是Negative Temperature Coefficient的缩写,意思是负的温度系数,泛指负温度系数很大的半导体材料或元器件,所谓NTC热敏电阻器就是负温度系数热敏电阻器。
它是以过渡金属氧化物为主要原材料,采用先进陶瓷工艺制造而成的。
这些金属氧化物材料都具有半导体性质,因为在导电方式上完全类似锗、硅等半导体材料。
温度低时,这些氧化物材料的载流子(电子和孔穴)数目少,所以其电阻值较高;随着温度的升高,载流子数目增加,所以电阻值降低。
NTC热敏电阻器在室温下的变化范围在100~1000000欧姆,温度系数-2%~-6.5%。
禾用这些特性,NTC热敏电阻器/温度传感器可广泛应用于温度测量、温度补偿、抑制浪涌电流等场合。

温度传感器选型[整理版]

NTC 温度传感器选型选择温度传感器比选择其它类型的传感器所需要考虑的内容更多。
首先,必须选择传感器的结构,使敏感元件的规定的测量时间之内达到所测流体或被测表面的温度。
温度传感器的输出仅仅敏感元件的温度。
实际上,要确保传感器指示的温度即为所测对象的温度,常常是很困难的。
在大多数情况下,对温度传感器的选用,需考虑以下几个方面的问题:(1)被测对象的温度是否需记录、报警和自动控制,是否需要远距离测量和传送。
(2)测温范围的大小和精度要求。
(3)测温元件大小是否适当。
(4)在被测对象温度随时间变化的场合,测温元件的滞后能否适应测温要求。
(5)被测对象的环境条件对测温元件是否有损害。
(6)价格如何,使用是否方便。
容器中的流体温度一般用热电偶或热电阻探头测量,但当整个系统的使用寿命比探头的预计使用寿命得多时,或者预计会相当频繁地拆卸出探头以校准或维修却不能在容器上开口时,可在容器壁上安装永久性的热电偶套管。
用热电偶套管会显著地延长测量的时间常数。
当温度变化很慢而且热导误差很小时,热电偶套管不会影响测量的精确度,但如果温度变化很迅速,敏感元件跟踪不上温度的迅速变化,而且导热误差又可能增加时,测量精确度就会受到影响。
因此要权衡考虑可维修性和测量精度两个因素。
热电偶或热电阻探头的全部材料都应与可能和它们接触的流体适应。
使用裸露元件探头时,必须考虑与所测流体接触的各部件材料(敏感元件、连接引线、支撑物、局部保护罩等)的适应性,使用热电偶套管时,只需要考虑套管的材料。
电阻式热敏元件在浸入液体及多数气体时,通常是密封的,至少要有涂层,裸露的电阻元件不能浸入导电或污染的流体中,当需要其快速响应时,可将它们用于干燥的空气和有限的几种气体及某些液体中。
电阻元件如用在停滞的或慢速流动的流体中,通常需有某种壳体罩住以进行机械保护。
当管子、导管或容器不能开口或禁止开口,因而不能使用探头或热电偶套管时,可通过在外壁钳夹或固定一个表面温度传感器的方法进和测量。

热电偶
▪ 热电偶由两种不同金属结合而成,它受热时会产 生微小的电压,电压大小取决于组成热电偶的两 种金属材料,铁-康铜(J型)、铜-康铜(T型)和铬铝(K型)热电偶是最常用的三种。
▪ 热电偶产生的电压很小,通常只有几毫伏。K型 热电偶温度每变化1℃时电压变化只有大约40μV, 因此测量系统要能测出4μV的电压变化测量精度 才可以达到0.1℃。

Series 65 Sensors are designed to meet the most critical parameters of international standards: IEC 751:1983, Amendment 1:1986 and2:1995 and DIN EN 60751:1996. This standardization provides sensor interchangeability without the need for transmitter circuitry adjustment.Enhanced performance and optimal temperature measurement accuracy is available for Series 65 Sensors coupled with a range of Rosemount Temperature Transmitters through calibration schedules and Callendar-Van Dusen constants.Series 185 Thermocouple Temperature Sensors conform to IEC 584:1982, Amendment 1:1989 and are available in types J, K, and N. Series 185 Sensors are available single ungrounded, or dual ungrounded, isolated.All sensors are available in a variety of lengths(1) and ranges with flying lead, terminal block, or ½-in. NPT spring-loaded adapter lead wire terminations.In addition to complete assemblies, Emerson offers a selection of separate accessory hardware including connection heads and thermowells.Selecting an extension and thermowellAside from ambient temperature variations, heat from the process, in a direct mounting configuration, is transferred from the thermowell to the transmitter housing. If the expected process temperature is near or beyond the transmitter specification limits,consider the use of additional thermowell extension length, an extension nipple, or a remote mounting configuration to isolate the transmitter from these excessive temperatures. Figure 3 provides an example of the relationship between transmitter housing temperature rise and extension length. Use Figure 3 and the accompanying example as a guide for determining adequate thermowell extension length.Figure 3: Transmitter Housing Temperature Rise vs. Uninsulated Extension Length605040302010075100125150175200225H o u s i n g R i s e A b o v e A m b i e n t (°C )Uninsulated Extension “N” Length (mm)A B CA.815 °C process temperatureB.540 °C process temperatureC.250 °C process temperature ExampleThe rated ambient temperature specification for the transmitter is 85 °C. If the maximum ambient temperature is 40 °C and the temperature to be measured is 540 °C, the maximum allowable housing temperature rise is the rated temperature specification limit minus the existing ambient temperature (85 – 40 °F), or 45 °C.As shown in Figure 3, an “N” dimension of 90 mm will result in a housing temperature rise of 22 °C. An “N” dimension of 100 mm would therefore be the minimum recommended length, and would provide a safety factor of about 25 °C. A longer “N” dimension,such as 150 mm, would be desirable in order to reduce errors caused by transmitter temperature effect, although in that case the transmitter may require extra support.Integral mount sensors and assembliesSeries 65 RTD and Series 185 Thermocouple Temperature Sensors may be ordered as complete assemblies, which provide a complete, yet simple, means of specifying the proper industrial hardware for most temperature measurements. One assembly model number, derived from one ordering table, completely defines the type of sensing element, as well as the material, length,and style of extension fittings and thermowells.All sensor assemblies are sized and inspected by Emerson to ensure complete component compatibility and performance.(1)Sensors over one meter long will be supplied coiled unless otherwise requested.Mounting configurationsSeries 65 Platinum RTDs and Series 185 ThermocouplesYou may order the Series 65 RTDs and the Series 185 Thermocouples with flying leads, a terminal block, or a ½-in. NPT spring-loaded adapter.Ordered with flying leads, the sensors are designed to be used with a head mount temperature transmitter attached directly to the sensor. The flying lead configuration allows the removal of the sensor and transmitter as one assembly.The BUZH connection head allows terminal block style sensors and transmitters to be mounted together. The transmitters in these assemblies will be mounted in the cover of the BUZH connection head.The sensors with a ½-in. NPT spring-loaded adapter are used with directly mounted Rosemount 3144P Field Mount Temperature Transmitters or through the use of Rosemount connection heads. This assembly requires a terminal block to be mounted inside the head.Hazardous area approvals are available with all three types of sensors, but they are dependent on the configuration of the entire temperature measurement assembly (see Product certifications).Temperature considerationsAmbient temperature limits for the connection head are –40 °C to +85 °C. The LT option may be extended down to a range of –51°C to +85 °C.Ambient temperature range addresses the connection head only, and requires suitable cable glands and field wiring provisions to meet the temperature requirements below –40 °C.Figure 4: Series 65 RTD Lead Wire ConfigurationSeries 65 RTD terminal block termination code 2Dual element (1)Red Red Wht321Red Red Wht654123456(1)The color of the terminal posts in the terminal block may not match the color of the lead wires connected to the capsule.Figure 5: Series 185 Lead Wire ConfigurationSeries 185 RTD thermocouple terminal block Dual elementSpecificationsSeries 65 Platinum RTD100 Ω RTD at 0 °C, α = 0.00385 °C-1Temperature range-50 to 450 °C (-58 to 842 °F) or -196 to 300 °C (-321 to 572 °F) depending on typeSelf heating0.15 °C/mW when measured per method defined in IEC 751:1983, Amendments 1 and 2Thermal response timeNine seconds maximum required to reach 50 percent sensor response when tested in flowing water according to IEC 751:1983, Amendments 1 and 2Immersion error60 mm minimum usable depth of immersion when tested according to IEC 751:1983, Amendments 1 and 2Insulation resistance1,000 MΩ minimum insulation resistance when measured at 500 Vdc and at room temperatureSheath material316 SST sensor tip (hot end) with 321SST mineral insulated cable constructionLead wirePTFE insulated, silver-coated, 0.21mm2 (24 AWG) stranded copper wire.

Rosemount Series 185 Thermocouple sensors are manufactured from selected materials to meet IEC 584 Tolerance Class 1. The junction of these wires is welded to form a pure joint, maintaining the integrity of the circuit and ensuring the highest accuracy. Ungrounded junctions are protected from the environment by the sensor sheath. The ungrounded and isolated junctions provide electrical isolation from the sensor sheath.Sheath materialRosemount thermocouples are made of a mineral insulated cable design with a variety of sheath materials available to suit both the temperature and the environment. For temperatures up to 800 °C in air, 1.4541 (321 SST) is standard. For temperatures from 800 to 1100 °C in air, 2.4816 (Alloy 600) is standard. For temperatures above 1100 °C, precious metal or ceramic protective sheaths are available upon request. For strongly oxidising or reducing atmospheres, consult your local Emerson representative.Lead wiresPTFE insulated, 0.52 mm2 (20 AWG) stranded thermocouple wire. Color coded per IEC 584.

除环境温度变化外,在直接安装组态中,来自过 程的热量自热电偶套管传导至变送器外壳。如果 预计过程温度接近或超出变送器技术规格极限要 求,应考虑附加热电偶套管延伸长度、采用延伸 接头或远程安装组态,从而将变送器与过量温度 隔离。图 1 给出了一个变送器外壳温度升高与延 伸长度的关系的实例。采用图 1 和随附的实例作 为指南,可以确定热电偶套管的足够延伸长度。
