What is the difference between explosion-proof thermocouple and armored thermocouple?

Armored thermocouple applications are usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the temperature of liquid, steam and gas media and solid surfaces within the range of 0℃ to 1300℃ in various production processes. Features Short thermal response time, reducing dynamic errors; can be bent and installed for use; large measurement range; high mechanical strength, good pressure resistance; working principle The electrode of the armored thermocouple is composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential.
Explosion-proof thermocouple applications are usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the temperature of liquid, steam and gas media and solid surfaces within the range of 0℃ to 1300℃ where explosives such as hydrocarbons exist at the production site. Features: Various explosion-proof forms, good explosion-proof performance; compression spring type temperature sensing element, good vibration resistance; large measuring range; high mechanical strength, good pressure resistance; working principle explosion-proof thermocouples use the gap explosion-proof principle to design components such as junction boxes with sufficient strength, and seal all parts that will generate sparks, arcs and dangerous temperatures in the junction box. When an explosion occurs in the box...
The difference between armored thermocouples and assembled thermocouples is: Simply put: the armored wire is made by a special manufacturer. Its protective tube, insulation layer, and wire are stretched out as a whole, with high strength, bendability, and no length influence. The assembled thermocouple is made of a 16 or other diameter stainless steel tube as a protective sleeve, which is covered with a thermocouple temperature sensing element with insulating porcelain beads, and then installed with a junction box. Both have their own strengths, and users can choose according to their needs.
Armored thermocouples have many advantages such as bendability, high pressure resistance, fast thermal response time and durability. Like industrial thermocouples, they are used as temperature sensors and are usually used in conjunction with display instruments, recording instruments and electronic regulators. At the same time, they can also be used as temperature sensing elements. It can directly measure the temperature of liquids, steam and its gaseous media and solid surfaces in the range of 0℃~800℃ in various production processes. Compared with, armored thermocouples have the advantages of bendability, high pressure resistance, short thermal response time and durability. As a temperature measurement sensor, armored thermocouples are usually used in conjunction with temperature transmitters, regulators and display instruments to form process control systems to directly measure or control the temperature of fluids, steam and gaseous media and solid surfaces in the range of 0-1800℃ in various production processes. Armored thermocouples have many advantages such as bendability, high pressure resistance, fast thermal response time and durability. Like industrial assembled thermocouples, they are used as temperature sensors and are usually used in conjunction with display instruments, recording instruments and electronic regulators. The temperature measurement principle of thermocouples is based on the thermoelectric effect. When two different conductors or semiconductors are connected into a closed loop, when the temperatures at the two junctions are different, a thermoelectric potential will be generated in the loop. This phenomenon is called the thermoelectric effect, also known as the Seebeck effect.
