The difference between multi-point armored thermocouples and armored thermocouples

The thermoelectric potential of armored thermocouples will increase as the temperature at the measuring end rises. The magnitude of the thermoelectric potential is only related to the material of the thermocouple conductor and the temperature difference at both ends, and is independent of the length and diameter of the thermoelectric electrode. Two conductors with different compositions are welded at both ends to form a circuit. The temperature measuring end is called the working end, and the wiring 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 circuit. When connected to a display instrument, the instrument will indicate the corresponding temperature value of the thermoelectric potential generated by the thermocouple.
Multi point armored thermocouple is a specially designed sensor for the chemical (fertilizer industry synthesis tower, reaction tank), metallurgical, petrochemical, and gas industries. When using this multi-point armored thermocouple, users need to bring their own external protective tube, otherwise they can only measure atmospheric pressure and non corrosive media. Multi point thermocouples are suitable for production sites where temperature gradients are not significant and multiple locations or single locations need to be measured simultaneously.
The structural principle of armored thermocouples is composed of a conductor, high insulation magnesium oxide, and a protective tube made of 1Cr18Ni9Ti stainless steel, which is pulled together multiple times. Armored thermocouple products are mainly composed of junction boxes, terminal blocks, and armored thermocouples, and are equipped with various installation and fixing devices. Armored thermocouples are divided into two types: insulated and shell connected.
Armored thermocouples have many advantages such as bending, high voltage resistance, fast thermal response time, and durability. Like industrial sensors, they are commonly used as temperature sensors and are often paired 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, vapors, gas media, and solid surfaces in the range of 0 ℃~800 ℃ during various production processes. Compared to others, armored thermocouples have advantages such as bendability, high voltage resistance, short thermal response time, and durability.
Armored thermocouples, as temperature measurement sensors, are usually used in conjunction with temperature transmitters, regulators, and display instruments to form process control systems. They are used to directly measure or control the temperature of fluids, vapors, gas media, and solid surfaces within the range of 0-1800 ℃ in various production processes.
