，使用壽命長(zhǎng)；抽芯式溫度計(jì)可不停機(jī)短時(shí)間維護(hù)或更換機(jī)芯
、化工、機(jī)械、船舶、發(fā)電、紡織、印染等工業(yè)和科研部門(mén)。">Widely used in petroleum, chemical, machinery, shipbuilding, power, textile, printing and dyeing industry and scientific research departments.。">The scene temperature display, intuitive and convenient safe and reliable, long service life; core pulling type thermometer can not stop short time maintenance or replacement of movement. 、135°型
WST series Digital display type double metal thermometer
。">It can directly measure the production process in a variety of -80 to +500 DEG C range of liquid, steam and gas temperature. 、萬(wàn)向型等品種齊全，適應(yīng)于各種現(xiàn)場(chǎng)安裝的需要
、應(yīng)用場(chǎng)合：">Three, application:。">The axial and radial type, 135 type, degree universal type, complete varieties, suitable for various on-site installation need.
、工作原理：">Two, work principle:
WST series Digital display type double metal thermometer Is the principle of expansion work in varying degrees of temperature change when using two different metals. 。">The main components for industrial use is one with two or more metal sheet laminated together to form a multilayer metal sheet. ，通常將金屬片制成螺旋卷形狀。">In order to improve the measurement sensitivity, usually made of sheet metals of spiral shape. ，各層金屬膨脹或收縮量不等，使得螺旋卷卷起或松開(kāi)。">When the multilayer metal sheet temperature changes, each layer of metal expansion or shrinkage range, so that the spiral rolled up or loosen.
，因此，當(dāng)雙金屬片感受到溫度變化時(shí)，指針即可在一圓形分度標(biāo)尺上指示出溫度來(lái)。">Since the end of the spiral coil is fixed and the other end and a pointer can rotate freely. Therefore, when the feeling of double sheet metal to temperature changes, in a pointer to the circular indexing on the gauge indicates the temperature to.
