Measurement methods1. Set the upper limit of the instrument alarm:Press and hold the Mode key for 2 seconds, to enter instrument setting, and press MODE key to shift to alarm upper limit setting, in this case, Hi is displayed in the instrument function indication zone, and the alarm upper limit is displayed in the zone. Press ▲/▼ key to increase or decrease the alarm value, and long press ▲/▼ key to accelerate the increase or decrease of the set value.2: Set the low alarm value of the instrumentPress and hold the Mode key for 2 seconds, to enter instrument setting, and press MODE key to shift to alarm lower limit setting, in this case, Low is displayed in the instrument function indication zone, and the alarm lower limit is displayed in the zone. Press ▲/▼ key to increase or decrease the alarm value, and long press ▲/▼ key to accelerate the increase or decrease of the set value.3: Set the instrument radiancePress and hold the Mode key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the instrument radiance setting, in this case, the instrument radiance indication zone flashes. Press the ▲/▼ key to increase or decrease the radiation value, and long press the ▲/▼ key to accelerate the increase or decrease of the set value.44: Set the instrument temperature unitPress and hold the MODE key for 2 seconds, to enter the instrument setting, and press the MODE key to shift to the instrument temperature measurement unit, the unit symbol on the display flashes, and press the ▲/▼ key to change the unit symbol.5: Exit the settingPress the trigger or long press the MODE key, to exit the instrument setting.6: Turn on/off laserPress the key to turn on or off laser, and the instrument will display the laser symbol7:Turn on or off back-lightPress the key to turn on or off back-light.8: Non-contact temperature measurementAim the thermodetector at the object, and hold the trigger, to conduct continuous measurement of temperature. After displaying stably, release the trigger, and the5When holding the trigger, the secondary display of the instrument will display the maximum value of the measured temperature.When the measured value is greater than the upper limit of high alarm or the measured value is less than the lower limit of low alarm, the red alarm indicator will turn on to alarm.6. Target distance ratio (D:S ratio)The thermodetector has a certain visual angle and visual field, as shown in the following figure.The measured target Tube Light-sensitive componentIn order to guarantee the measured object fills in the visual field of the thermodetector, which means the thermodetector only "sees" the measured object rather than other objects. Larger objects may cause larger temperature measurement distances; for smaller objects, the measurement distances must be close. The ratio of measurement distance to the measured target (D:S) is 12:1, as shown in the following figure:677. RadianceThe radiance characterizes the ability of an object to radiate infrared ray. Larger radiance will lead to stronger radiation ability on the object surface.Radiance of the majority of organic matters or metal oxidized surfaces ranges between 0.85 and 0.98. The radiance of the thermodetector is 0.95 by default. During measurement, set the radiance of the instrument the same with the radiance of the measured object. During measurement, please pay attention to the impact of emissivity on measurement results.The following table is the radiance reference table.Measured surfaceRadiance Aluminum Oxidized0.2~0.4A3003alloy (oxidized)0.3A3003alloy (coarse)0.1~0.3Brass Polishing0.3Oxidized0.5 Copper Oxidized0.4~0.80.6Electrical terminalboardHastelloy0.3~0.8 Ferro-nickel Oxidized0.7~0.95Abrasive blasting0.3~0.6Electropolishing0.15Iron Oxidized0.5~0.9Rust0.5~0.7 Iron(casting)Oxidized0.6~0.95Unoxidized0.2Fusion cast0.2~0.3 Iron(casting)passivation0.9Lead Coarse0.4Oxidized0.2~0.6 Molybdenum oxidation0.2~0.68Nickel oxidation0.2~0.5 Platinum black0.9 Steel Cold rolling0.7~0.9Grinding steel plate0.4~0.6Polished steel plate0.1 ZincOxidized0.1 Asbestos0.95 Asphalt0.95 Basalt0.7 Carbon(unoxidized)0.8~0.9 Graphite0.7~0.8 Silicon carbide0.9 Ceramics0.95 Clay0.95 Concrete0.95 Cloth0.95 Glass plate0.85 Gravel0.9519LCD displayColor LCD display D:S12:18.

This voltage is called thermoelectric voltage or electromotive force (emf.). Its magnitude depends on the type of conducting materials and the temperature difference between the "measuring point" (the junction of the two conductors) and the "cold junction" (the open conductor ends). Accordingly, thermocouples primarily only measuredifferences in temperature. The absolute temperature at the measuring point can be determined from these if the associated temperature at the cold junction is known or is measured separately and compensated for. The material combinations and associated thermoelectric voltage/temperature characteristics of the most common types of thermocouple are standardized in the IEC 60584 and ASTM E230/ANSI MC96.1 standards.Measuring range Performance characteristicsAccuracyPermissible deviation limits of thermoelectric voltages from standard characteristic for thermocouples as per IEC 60584 or ASTM E230/ANSI MC96.1:InputDesignationMeasuring range limitsThermocouples (TC)1) as per IEC 60584Type J (Fe-CuNi)Type K (NiCr-Ni)Type S (PtRh10-Pt)Type R (PtRh13-Pt)Type B (PtRh30-PtRh6)-210… +1200 °C (-346… +2192 °F), typical sensitivity ≈ 55 μV/K -270… +1372 °C (-454… +2502 °F), typical sensitivity ≈ 40 μV/K -50… +1768 °C (-58… +3214 °F), typical sensitivity ≈ 11 μV/K -50… +1768 °C (-58… +3214 °F), typical sensitivity ≈ 13 μV/K 0…+1820 °C (+32... + 3308 °F), typical sensitivity ≈ 9 μV/K1) Typical sensitivity above 0 °C (+32 °F)StandardTypeStandard tolerance Special tolerance IEC 60584ClassDeviationClass DeviationJ (Fe-CuNi)2±2.5 °C (-40...333 °C)±0.0075 |t|1) (333...750 °C)1 ±1.5 °C (-40...375 °C)±0.004 |t|1) (375...750 °C)K (NiCr-Ni)2±2.5 °C (-40...333 °C)±0.0075 |t|1) (333...1200 °C)1 ±1.5 °C (-40...375 °C)±0.004 |t|1) (375...1000 °C)R (PtRh13-Pt) and S (PtRh10-Pt)2±1.5 °C (0...600 °C)±0.0025 |t|1) (600...1600 °C)1±1 °C (0...1100 °C)±[1 + 0.003(|t|1)-1100)] (1100 °C...1600 °C)S (PtRh13-Pt)21B (PtRh30-PtRh6)2±1.5 °C or±0.0025 |t|1) (600...1700 °C)--1) |t| = Absolute temperature value in °CTPC200Endress+Hauser 3Calibration specificationsEndress+Hauser provides comparison temperature calibration from -80 to +1400 °C (-110 °F to 2552°F) based on the International Temperature Scale (ITS90).

三系统组成及工作原理VST.R-200系列测温元件自动检定系统的组成如图1-1和图1-2所示。
当检定工业热电偶时:把标准热电偶放入一支内径6mm的石英玻璃管内并且和被检热电偶捆扎在一起,而且所有热电偶的感温头要处于同一截面上,然后装在管式检定炉的最高温区。
热电偶通过补偿导线延长至冷端与铜导线相接(标准热电偶可直接接铜导线),其接点置于冰点恒温器中以保正热电偶冷端为0℃。
与热电偶补偿导线相接的铜导线接至VST.R-200系列检测仪的信号输入端,VST.R-200系列检测仪可接受微机指令,按双极法的检定要求切换各检测通道,使高精度数字万用表的测量端与相应的测点回路相通,数字万用表按照微机的指令进行电势测量并把测得电势值送回微机。
微机是热电偶自动检定过程的控制者,它根据检定工作的需要,控制切换开关的切换工作和数字万用表的数据采样工作,根据测得的标准热电偶热电势换算出当前的炉内温度,并按照设定温度点的要求控制VST.R-200系列伺服器,改变检定炉的加热电流,从而实现检定炉炉温的自动控制。
当检定炉的炉温达到某设定温度的检定点要求时,微机则控制切换开关巡回切向标准热电偶和各被检热电偶,每切换一路,高精度数字万用表就测量该回路的热电势并把所测的热电势信号值传送给微机存储待用,当该检定点按要求检测完毕,微机自动转向下一个温度检定点。
当所设定的温度检定点都检测完毕,微机则按检定规程的要求做检定计算,然后整理检定结果并记录在固定格式的测量记录和数据综合表中,用户可在微机上随时调用所有检定报表,查看或打印。
当检定工业热电阻时,把标准铂电阻温度计和被检热电阻插入油槽(水槽)或冰点恒温器中,标准铂电阻温度计、标准电阻(100Ω)和被检热电阻分别经检测导线接至VST.R-200系列检测仪的信号输入端,并把标准铂电阻和被检热电阻以及标准电阻串联接上1mA的恒定电流,并使高精度数字万用表的测量端与VST.R-200系列检测仪输出端相接。
VST.R-200系列检测仪接受微机指令,按检定热电阻的要求巡回切换开关,高精度数字万用表由微机控制进行电势测量并把测得的数据送回微机。
微机是热电阻自动检定过程的控制者,它按照检定工作的要求,控制切换开关的切换工作和高精度数字万用表的数据采集工作,根据测得的标准铂电阻温度计和标准电阻的数据换算出当前的槽内温度,并按照设定温度点的要求控制VST.R-200系列伺服器,改变检定油槽的加热电流,从而实现恒温油槽或恒温水槽的自动控温。
当油槽的温度达到设定温度的检定要求时,微机则控制切换开关巡回检测标准铂电阻温度计、标准电阻和各被检热电阻的数据,每切换一路,就令高精度数字万用表测量该回路的数据,并把所测数据传给微机存储待用。
当所有的检定数据获得后,微机则可根据用户的选择,按照检定规程的要求进行检定计算,然后整理检定图1-1 热电偶检定原理图结果并记录在固定格式的测量记录和数据综合表中,用户可随时调用所有检定报表,查看或打印。
