具有能弯曲、耐高压、热响应时间快和坚固耐用等许多优点，它和工业用装配式热电偶一样,作为测量温度的变送器，通常和显示仪表、 Micro-armored thermocouples have many advantages such as flexibility, high pressure resistance, fast thermal response time, and ruggedness. They are the same as industrial assembled thermocouples.
Recording instrument and electronic regulator are used together, and it can also be used as the temperature sensing element of assembled thermocouple. It can directly measure liquid, steam and gas medium and solid in the range of 0 ~ 800 ℃ during the production process.
Surface temperature. It is suitable for temperature measurement and control in narrow and curved places. It is an indispensable temperature measuring device for chemical fiber, pharmaceutical and other industries
工作原理： Working principle of micro-armored thermocouple :
Two ends of conductors of two different components are welded to form a loop. The direct temperature measurement end is called the working end, and the connection terminal end is called the cold end, also known as the reference end. When there is a temperature difference between the working end and the reference end, a thermal current will be generated in the loop.
Connect the display meter, and the corresponding temperature value of the thermoelectromotive force generated by the thermocouple will be indicated on the meter
The thermoelectromotive force of the armored thermocouple will increase as the temperature of the measurement terminal increases. The size of the thermoelectromotive force is only related to the material of the thermocouple conductor and the temperature difference between the two ends, and has nothing to do with the length and diameter of the thermocouple
The structural principle of the armored thermocouple is that it is made of a conductor, a high-insulation magnesium oxide, and a 1Cr18Ni9Ti stainless steel protective tube, which is integrally drawn several times. Armored thermocouple products are mainly composed of junction boxes, terminals and armored thermocouples.
The basic structure is composed of various pairs, and is equipped with various installation and fixing devices.
There are two types of armored thermocouples: insulated and shell-type.
Application of micro-armored thermocouple
It is suitable for temperature measurement and control in narrow bending places. It is an indispensable temperature measuring device for chemical, chemical fiber and pharmaceutical industries. Because the outer tube is very thin, the response speed is fast.
