Thermocouple structure
The basic structure of the thermocouple is a hot electrode, an insulating material and a protective tube; and it is used in conjunction with a display instrument, a recording instrument or a computer. In the field use, according to the environment, the measured medium and other factors to develop a thermocouple suitable for various environments. Thermocouples are simply divided into fabricated thermocouples, armored thermocouples and special-type thermocouples; subdivided by high temperature thermocouples, wear-resistant thermocouples, corrosion-resistant thermocouples, high-voltage thermocouples, and explosion-proof thermoelectrics Even, thermocouple for aluminum liquid temperature measurement, thermocouple for circulating fluidized bed, thermocouple for cement rotary kiln, thermocouple for anode baking furnace, thermocouple for high temperature hot blast stove, thermocouple for vaporization furnace, thermoelectric for carburizing furnace Even, thermocouples for high temperature salt bath furnaces, thermocouples for copper, iron and steel, thermocouples for anti-oxidation, tungsten, thermocouples for vacuum furnaces, platinum-iridium thermocouples, etc.
Intelligent temperature sensor(thermocouple):
Intelligent temperature sensors (also known as digital temperature sensors) were introduced in the mid-1990s.
It is the result of microelectronics, computer technology and automated test technology (ATE). At present, a variety of intelligent temperature sensor products have been developed internationally.
The intelligent temperature sensor internally contains a temperature sensor, an A/D converter, a signal processor, a memory (or register), and an interface circuit. Some products also come with a multiplexer, central controller (CPU), random access memory (RAM) and read only memory (ROM). The intelligent temperature sensor is characterized by the ability to output temperature data and associated temperature control quantities to accommodate a variety of microcontrollers (MCUs). And it is based on the hardware to achieve the test function through software, and its degree of intelligence depends on the level of software development.
