style="text-indent:25px">利用溫差電偶來測量溫度的溫度計。將兩種不同金屬導(dǎo)體的兩端分別連接起來，構(gòu)成一個閉合回路，一端加熱，另一端冷卻，則兩個接觸點之間由于溫度不同，將產(chǎn)生電動勢，導(dǎo)體中會有電流發(fā)生。因為這種溫差電動勢是兩個接觸點溫度差的函數(shù)，所以利用這一特性制成溫度計。若在溫差電偶的回路里再接入一種或幾種不同金屬的導(dǎo)線，所接入的導(dǎo)線與接觸點的溫度都是均勻的，對原電動勢并無影響，通過測量溫差電動勢來求被測的溫度，這樣就構(gòu)成了溫差電偶溫度計。這種溫度計測溫范圍很大。例如，銅和康銅構(gòu)成的溫差電偶的測溫范圍在200～400℃之間；鐵和康銅則被使用在200～1000℃之間；由鉑和鉑銠合金（銠10%）構(gòu)成的溫差電偶測溫可達(dá)千攝氏度以上；銥和銥銠（銠50%）可用在2300℃；若用鎢和鉬（鉬25%）則可高達(dá)2600℃。</p><p
