 二(èr)，工作原理 Operation Theory

雙金(jīn)屬(shǔ)溫度計采(cǎi)用多圈直(zhí)螺旋(xuán)形(xíng)雙金屬片，一端固定(dìng)，另一端(duān)（自(zì)由端）連接在(zài)芯(xīn)軸上，軸(zhóu)向型溫度計指針(zhēn)直接裝(zhuāng)在軸上，徑向型(xíng)溫度(dù)計(jì)指針通(tōng)過(guò)轉角簧(huáng)與(yǔ)芯軸(zhóu)連(lián)接。當溫度(dù)變化時(shí)，感溫(wēn)元件自由端旋(xuán)轉，經芯軸傳(chuán)動指(zhǐ)針(zhēn)在(zài)刻度盤上指示(shì)出被測介質溫度的(dí)變(biàn)化值(zhí)。

Bimetallic thermometer is based on bimetal bended into ring shape. One side of bimetal expands in time of being heated, which results in revolving of indicator, and then the meter indicates corresponding temperature value to pyroelectric potential.

電接點(diǎn)雙金屬溫(wēn)度計是(shì)利用溫度變化(huà)時帶(dài)動(dòng)觸(chù)點變(biàn)化(huà),當其上(shàng)下限觸(chù)點(diǎn)接觸或(huò)斷(duàn)開的同時，使電路(lù)中的繼電器(qì)動作，從而自(zì)動控(kòng)製及報(bào)警。

For bimetallic thermometer with electric contact, the change of the temperature resultsin the change of contact. The relay When its up & down contact contacts or breaks down。

防(fáng)爆雙(shuāng)金屬溫(wēn)度計(jì)是利用(yòng)間隙隔爆原理，設(shè)計(jì)具有足(zú)夠強(qiáng)度的(dí)接(jiē)綫(xiàn)盒(hé)等(děng)部件，將所有會(huì)產(chǎn)生火花(huā)，電弧和(hé)危(wēi)險(xiǎn)溫度的零部件(jiàn)都(dū)密(mì)封在內(nèi)腔內(nèi)，當內腔內(nèi)發(fā)生(shēng)爆(bào)炸時，能通(tōng)過結合(hé)麵間隙熄火(huǒ)和(hé)冷(lěng)卻(què)，使(shǐ)爆炸後(hòu)的火(huǒ)焰(yàn)和溫(wēn)度不(bù)傳(chuán)到腔(qiāng)外。

Explosion-proof bimetallic thermometer is designed to make use of space explosion-proof theory, making all parts which will produce spark, arc and dangerous temperature be sealed within inner chamber. When explosion happened within inner chamber, by intermittent cooling and flameout of binding face, spark and temperature can be controlled within inner chamber after explosion.
