Armored thermocouple as the temperature measurement sensor, usually with a temperature transmitter, regulator and display instruments, such as supporting the use, composition, process control system, by direct measurement or control of various production process 0-1800 DEG C within the fluid, steam and gas medium and solid surface, such as surface temperature. Armored thermocouple has to bending, resistance to high pressure, thermal response time fast and durable and so on many merits, it and industrial assembly type thermocouple, as the temperature measurement sensor and usually display instruments, recording instruments and electronic regulating device supporting the use of.
Armored thermocouple has to bending, resistance to high pressure, thermal response time fast and durable and so on many merits, it and industrial assembly type thermocouple, as the temperature measurement sensor and usually display instruments, recording instruments and electronic regulating device supporting use. At the same time, but also as a assembly type thermocouple temperature sensing element. It can directly measure the temperature of liquid, vapor and its gas medium and solid surface in various production processes from 0 to ~800. Compared with the assembly type thermocouple, armoured thermocouple with bending, resistance to high pressure, thermal response time short and sturdy and durable advantages.
Two different components of the conductor at both ends of the weld, the formation of the loop, the direct test temperature is called the working end, the terminal end of the terminal called the cold end, also known as the reference. When the working end and reference than the end of the temperature, it will in the loop produce thermal current, connected to the display instrument, instrument will indicate the corresponding temperature of thermocouple thermoelectric EMFs values. Armored thermocouple electromotive force will be with the increase of temperature of measuring end and growth, thermoelectric EMFs size only thermocouple conductor material and the temperature difference between the two ends and the thermoelectric and the length and diameter of irrelevant. Structure principle of armored thermocouple is consists of a conductor, a high insulating magnesium oxide, coat of 1Cr18Ni9Ti stainless steel protection tube, drawing from several integration and. Armored thermocouple products mainly by the junction box, terminal and sheathed thermocouple components basic structure, and with various fixed device.
