Thermocouple Measurement
In 1822, Thomas Seebeck, an Estonian physician, accidentally joined semicircular pieces of bismuth and copper (Figure 1) while studying thermal effects on galvanic arrangements. A nearby compass indicated a magnetic disturbance. Seebeck experimented repeatedly with different metal combinations at various temperatures, noting relative magnetic fi eld strengths. Curiously, he did not believe that...
متن کاملUltrafast response micropipette-based submicrometer thermocouple
Submicrometer-size thermocouples at the tip of gold-coated glass micropipettes containing a platinum core were produced and tested. The response time of such thermocouples measured with different techniques appeared to be not bigger than a few microseconds. The calculations indicate that the spatial selectivity of this new class of thermocouple devices can be less than 2 pm along the pipette an...
متن کاملDecreasing of thermocouple inhomogeneity impact on temperature measurement error
One of the most effective methods of reducing the impact of error due to acquired thermoelectric inhomogeneity of thermocouples' electrodes is discussed in this article. The method consists in stabilizing the profile of the temperature field along electrodes of the main thermocouple (which measures the temperature of the object). There is also discussed the design of device for profile stabiliz...
متن کاملEffects of thermocouple electrical insulation on the measurement ofᅡᅠsurface temperature
Analytical, numerical and experimental analyses have been performed to investigate the effects of thermocouple wire electrical insulation on the temperature measurement of a reference surface. Two diameters of type K thermocouple, 80 mm and 200 mm, with different exposed wire lengths (0 mm, 5 mm, 10 mm, 15 mm and 20 mm) were used to measure various surface temperatures (4 C, 8 C, 15 C, 25 C and...
متن کاملfeatures of short story in translated and non-translated literature: a polysystemic perspective
ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
