Description

Верхний предел измерени  существующих термометров сопротивлени  не превышает нескольких сот градусов при точности и стабиль ности показаний, не удовлетвор ющих современным требовани м.The upper limit of measurement of existing resistance thermometers does not exceed several hundred degrees with an accuracy and stability of indications that do not meet modern requirements.

Предлагаемый чувствительный элемент термометра сопротивлени  дл  повышени  верхнего предела измерени  и увеличени  стабильности и точности показани  термометра сопротивлени  изготовлен из монокристальной проволоки.The proposed sensitive element of the resistance thermometer to increase the upper limit of measurement and increase the stability and accuracy of the resistance thermometer is made of a single crystal wire.

В св зи с возросшими требовани ми к качеству металлов, сплавов и других материалов по вилась необходимость более точного измерени  и регулировани  температуры технологических процессов до дес тых и сотых долей градуса при температуре измерени  пор дка + 1500-1800°.In connection with the increased quality requirements of metals, alloys and other materials, it was necessary to more accurately measure and control the temperature of technological processes to the tenth and hundredths of a degree at a temperature of the order of + 1500-1800 °.

Примен емые термо.метры сопротивлени  имеют верхний прелсл-г измерени  примерно 500-700°.The applied thermal resistance meters have an upper measurement height of about 500-700 °.

Точность измерени  температуры и верхний предел измерени  термометров сопротивлени  в большой степени зависит от скорости испарени  материала чувствительного элемента, а также от степени рекристаллизации проволоки чувствительного элемента.The accuracy of temperature measurement and the upper limit of measurement of resistance thermometers largely depend on the evaporation rate of the material of the sensing element, as well as on the degree of recrystallization of the sensing element wire.

В свете изложенного возникла необходимость изготовлени  более совершенных датчиков сопротивлени .In the light of the foregoing, the need has arisen to manufacture more sophisticated resistance sensors.

Применение монокристальной проволоки дл  изготовлени  чувствительных элементов термометров сопротивлени  позволит увеличить точность измерени  температуры и значительно повысит верхний предел измерени  термометров, так как испарение монокристаллов значительно меньше поликристаллов и в меньшей степени вли ют механические воздействи .The use of single-crystal wire for the manufacture of sensitive elements of resistance thermometers will increase the accuracy of temperature measurement and significantly increase the upper limit of measurement of thermometers, since the evaporation of single crystals is much smaller than polycrystals and to a lesser extent mechanical effects.

№ 147343- 2 No. 147343-2

Кроме того, при высоких температурах измерени  исключаетс  вли ние процесса рекристаллизации проволоки чувствительного элемента на точность замеров. In addition, at high measurement temperatures, the influence of the recrystallization process of the sensing element wire on the measurement accuracy is eliminated.

Предлагаемый чувствительный элемент получил положительную оценку.The proposed sensing element received a positive rating.
