What's the difference between a thermocouple and micro thermocouple _ instrument

Micro thermocouple can bend, high pressure resistance, heat fast response time and strong and durable and many other advantages. By welding on both ends of the two different ingredients of conductor, form a loop, directly measuring WenDuan call work side, the terminal end is called the cold end, also known as the reference. When work end and reference end there is temperature difference, will produce thermal current in the circuit, connected to display instrument, the instrument will indicate the thermocouple thermoelectric emf generated by the corresponding temperature value. The thermocouple thermoelectric emfs growth over the course of measuring the temperature, the size of the thermoelectric emfs and thermocouple temperature difference on both ends of the conductor material and, only has nothing to do with hot electrode length and diameter. The structure principle of thermocouple is, is made up of a conductor, high insulation magnesium oxide, coat 1 cr18ni9ti stainless steel protecting tube, after many integrated control. Thermocouple products are mainly composed of terminal block, terminal and thermocouple basic structure, and with various mounting device. Thermocouple insulation type and hull type two kinds. Thermocouple and fitting the difference between the thermocouple are: simple said: the wire is produced by specialized manufacturers of its protection tube, insulating layer, accidentally wire stretched out a whole, has high strength, flexible, not influenced by the length, thermocouple assembly is made from 16 or other diameter stainless steel tube protective sleeve, inside has good wear insulating porcelain beads on set of thermocouple temperature sensing element, mount junction box, both the strengths and the user can choose according to need. Thermocouple can bend, high pressure resistance, heat fast response time and strong and durable many advantages, such as it and industrial use, as measure temperature sensor, and usually display meter, recording meter and electronic regulator, at the same time, also can be used as a temperature sensing element. It can directly measure all kinds of production process from 0 ℃ ~ 800 ℃ in the scope of liquid, steam and gas medium, as well as the surface temperature of the solid. And compared to the thermocouple is flexible, high pressure, the advantages of thermal response time is short and strong and durable. Thermocouple as the temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature. Thermocouple temperature measurement principle is based on thermoelectric effect. Connect the two different conductor or semiconductor into closed loops, when the two contacts in temperature is not at the same time, the circuit will produce thermoelectric potential, this kind of phenomenon called the thermoelectric effect, also known as the seebeck effect.
