问:
最适合于创造高温金属温度计这是什么?

答:
温度计温度计是设备的总称。根据不同的温度和在不同地区不同的物质的温度,用煤油温度计,酒精温度计,水银温度计,气体温度计,电阻温度计,热电偶温度计,辐射温度计和温度计和光学测量。
电阻温度计电阻温度计分为金属和半导体电阻温度计划分,是根据与此功能使温度电阻变化。金属温度计主要有用铂,金,铜,镍和其他金属和铑纯铁,磷青铜合金,半导体温度计主要是碳,锗等。电阻温度计使用方便可靠(Coco),得到了广泛应用。其-260 ° C测量范围为600℃左右。
热电偶温度计是一种广泛使用的工业温度计装置。由热电现象的使用。两种不同的金属丝焊接在一起,形成一个工作方面,以及在两端测量连接在一起,形成一个电路其他文书。工作温度的测量方在与温度的同时自由端工作的结束,将有电动势,因此是通过电路的电流。通过电气量的测量,在已知的温度使用,我们可以决定一个温度。这种多用途温度计,铜-康铜,铁-康铜,镍铭-康铜,金钴-铜,铂-铑等。它适用于两种物质之间的温差较大,高温和低浊度测量。有些热电偶测量温度可达3000 ° C,并且可以在一些接近{jd1}零度的低温测量。
温度温度计是用来测量500℃以上的温度计,温度计测量的温度比色温度计和辐射温度计光明(Guangming)的。
我们通常使用的玻璃温度计,水银温度计,大多。内有水银。汞的沸点356.95℃,这是通常用来测量温度不够。然而,业界,有时数千度测量温度,这样一来,水银温度计不能英寸转向金属镓的人来帮助。
1镓高沸点为2070℃,熔点低,只有29.78℃。换句话说,到一个人的体温手中镓将能够使它融化。该决定的性质与镓,衡量29.78℃至2070℃的温度最合适。人们填充到高温镓薄石英管,主要广泛使用在工业领域的高温的。
镓的使用也多了。这是一个很好的半导体材料。可用于电子设备。此外,镓,很容易含有合金熔。根据与镓镓或一人的特点,锡合金锌合金,使消防设备的设备。当点火,一个升温,保险股将融化,火灾自动打开水龙头,自来水,将发出火警。

Most suitable for manufacturing high-temperature thermometer metal What is this?

Question:
best suited to create high-temperature thermometer metal What is this?

Answer:
thermometer thermometer is the general term for devices. Depending on the temperature and the temperature of different substances in different areas, with kerosene thermometer, alcohol thermometer, mercury thermometer, gas thermometer, resistance thermometers, thermocouple thermometers, radiation thermometers and thermometer and optical measurements.
resistance thermometer resistance thermometer is divided into metal and semiconductor resistance thermometers, are based on changes in resistance with temperature made of this feature. Metal thermometer mainly useful for platinum, gold, copper, nickel and other metals and rhodium pure iron, phosphor bronze alloy; semiconductor thermometer mainly carbon, germanium, etc.. Resistance thermometer easy to use and reliable, has been widely applied. Its measurement range of -260 ° C to  600 ° C or so.
thermocouple thermometer is a widely used industrial thermometer device. Made of the use of thermoelectric phenomena. Two different kinds of metal wire welded together to form a working side, and the other at both ends and measuring instruments connected to form a circuit. Work-side on the measured temperature at the working end with the free end of the temperature at the same time, there will be electromotive force, so there is current through the circuit. Through the measurement of electrical quantity, using known at the temperature, we can determine the temperature of another. This multi-purpose thermometer, copper - constantan, iron - constantan, nickel-ming - constantan, gold cobalt - copper, platinum - rhodium so on. It applies to the larger temperature difference between the two substances, used for high temperature and low turbidity measurements. Some thermocouple to measure temperatures up to 3000 ° C, and some can be measured at low temperature near absolute zero.
temperature thermometer is designed to measure temperatures above 500 ° C thermometer, thermometer measuring bright than the color thermometers and radiation thermometers.
we usually used a glass thermometer, mercury thermometer, mostly. Inside filled with mercury. The boiling point of mercury 356.95 ℃, which is sufficient for measuring the temperature normally used. However, the industry and sometimes thousands of degrees to measure the temperature, this way, the mercury thermometer can not be used in. People turned to the metal gallium to help.
  a high boiling point of gallium, for 2070 ℃, but the melting point is low, only 29.78 ℃. In other words, the gallium into the hands of a person s body temperature will be able to make it melt. The nature of the decision, with the gallium to measure 29.78 ℃ to 2070 ℃ the temperature most suitable. People have filled into the high-temperature gallium thin quartz tube, made of high temperature of the main, widely used in industrial fields.
  use of gallium is also more than that. It is an excellent semiconductor material. Can be used for electronic equipment. In addition, the gallium-containing alloys are easily fusible. According to the characteristics of people with gallium or a gallium-tin alloy zinc alloy to make fire device device. When the ignition, the temperature of a rise, the insurance unit will be melting, fire automatically open the faucet, tap water that would emit fire.
