TERMICS熱電偶產(chǎn)品介紹
熱電偶基本上由任意兩根異種金屬線組成,一端機械連接,稱為熱接點; 另一端(或冷端)處于已知參考溫度(通常為 0°C),該溫度低于熱端的溫度。
當(dāng)熱接點被加熱時,會產(chǎn)生通常與溫度成正比的電動勢。 溫度/電壓關(guān)系是可重復(fù)的。
優(yōu)點
任何一對導(dǎo)體都可以用作熱電偶,這就是選擇滿足以下要求的合金并使其標(biāo)準(zhǔn)化的原因:
每℃排放量高
良好的穩(wěn)定性和重復(fù)性
良好的機械性能
低成本
冶金純度
溫度/fem特性盡可能呈線性
以下是最常見的工業(yè)熱電偶
B型 : (Pt 30% Rh / Pt 6% Rh)
E型 : (Chromel / Constantan)
J型 : (Iron / Constantan)
K型 : (Chromel / Alumel)
S型 : (Pt 10% Rh / Platinum)
R型 : ( Pt 13% Rh / Platinum)
T型 : (Copper / Constantan)
N型 : (Nicrosil / Nisil)
A thermocouple basically consists of any two dissimilar metal wires mechanically joined at one end, called the hot junction; the other end – or cold junction – is at a known reference temperature (usually 0°C), which is lower than the temperature of the hot junction.
When the hot junction is heated, this generates an electromotive force that is normally proportional to the temperature. The temperature/voltage relationship is repeatable.
BENEFITS
Potentially any pair of conductors can be used as a thermocouple, which is why alloys meeting the following requirements have been selected and standardised:
high emission per °C
good stability and repeatability
good mechanical properties
low cost
metallurgical purity
temperature/fem characteristic as linear as possible
Here are the most common industrial thermocouples
Type B : (Pt 30% Rh / Pt 6% Rh)
Type E : (Chromel / Constantan)
Type J : (Iron / Constantan)
Type K : (Chromel / Alumel)
Type S : (Pt 10% Rh / Platinum)
Type R : ( Pt 13% Rh / Platinum)
Type T : (Copper / Constantan)
Type N : (Nicrosil / Nisil)
