When electrolyte is present, the use of different materials(such as A2-C2, A4-C4, or A2-A4 bolt-nut combinations)risks galvanic corrosion.
请注意,铂基热电偶的输出功率非常低,这就解释了为什么它们的使用仅限于测量高温。
Note the platinum based thermocouples have a very low output which explains why there use is limited to the measurement of high temperatures.
这一产生的电压虽然很小,但确实意味着热电偶(与RTD和热敏电阻不同)是自供电的,不需要激励电流。
This generation of a voltage, albeit small, does mean thermocouples(unlike RTDs and thermistors) are self-powered and require no excitation current.
基础金属热电偶的负载热电偶使用限制还涉及温度和使用次数以及日历时间。
Load thermocouple usage limits for base metal thermocouples also involve temperature and number of uses, as well as calendar time.
这些可靠的金属组合称为热电偶类型(它们也不时被非正式地称为热电偶校准)。
These reliable combinations of metals are called thermocouple types(they are also informally referred to from time to time as thermocouple calibrations).
这使得热电偶和红外线高温计或成像仪成为测量温度高于1000°C(1832°F)的最合适设备。
That leaves thermocouples and infrared pyrometers or imagers as the most suitable devices for measuring temperatures above 1000°C(1832°F).
这些暴露的交界处热电偶被认为是响应速度最快的,最适合非腐蚀性气体和干燥空气温度测量。
These exposed junction thermocouples are considered the fastest responding and the best suited for non-corrosive gas and dry air temperature measurements.
金铂热电偶通常选用铂-铑(R,S和B型)热电偶,稳定性和均匀性至关重要。
Gold-platinum thermocouples are often chosen above platinum-rhodium(Type R, S and B) thermocouples where stability and homogeneity are critical.
五年后,贝克雷尔提议用铂-铂热电偶进行温度测量,但直到1829年才由利奥波德真正创造了这个设备。
Five years later, Becquerel proposed using a platinum-platinum thermocouple for temperature measurement, but it took until 1829 for Leopoldi Nobili to create a working device.
AMS2750建立了控制热电偶使用的特定要求,过程所有者必须了解这些要求并且质量体系必须解决。
AMS2750 establishes the specific requirements for controlling thermocouple usage which the Process Owner must understand and the Quality System must address.
