The structure of armored thermal resistance is the same as that of conventional thermal resistance, 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: The temperature measuring element is a temperature sensing element and its internal lead for the thermistor; Use oxidation bonding as insulation material between the leads of each thermistor and between them 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 and flexible compact entity. Armor material is the base material for manufacturing armor thermal resistors, Armor material cannot be directly used for temperature measurement. Measurement terminals and simple wiring terminals must be made before it can be used as a basic armored thermistor.
