Working principle

The working principle of armored thermocouples is to weld two conductors with different compositions at both ends to form a circuit. The direct measuring end is called the measuring end, and the wiring terminal is called the reference end. When there is a temperature difference between the measuring 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 type generated by the thermocouple.
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 armored thermocouple conductor and the temperature at both ends, and is independent of the length and diameter of the thermoelectric electrode.
The structure of armored thermocouples is made by repeatedly drawing conductors, insulating oxide molds, and protective tubes made of 1Cr18Ni9Ti stainless steel. Armored thermocouple products are mainly composed of junction boxes, terminal blocks, and armored thermocouples, and are equipped with various fixed devices.

Structure of Armored Thermocouples Product Structure

The structure of armored thermocouples is the same as that of conventional assembled thermocouples, except that the temperature measuring element, insulation material, and protective sleeve in the five parts form the entire armor material.
Armor material (temperature measuring element, insulation material, protective sleeve): For thermocouples, temperature measuring elements are two positive and negative thermocouple wires, and magnesium oxide is used as insulation material between each thermocouple wire and the protective sleeve; Protect insulation materials and temperature measuring components with metal tubes. The armor material process makes the temperature measuring element, insulation material, and protective sleeve a non removable, flexible, and compact entity. Armor material is the base material for manufacturing armored thermocouples, and cannot be directly used for measurement. Measurement terminals and simple wiring terminals must be made before it can be used as a base type armored thermocouple.
