The working principle of armoured thermocouple

Are two different components of conductor on both ends of the welding and form a loop, directly measuring WenDuan call work side, the terminal end is called the cold end, also known as the reference. When work end and reference end there is temperature difference, will produce thermal current in the circuit, connected to display instrument, the instrument will indicate the thermocouple thermoelectric emf generated by the corresponding temperature value. Armoured thermocouple thermoelectric emf will grows with the temperature measuring end, only the size of the thermoelectric emfs and thermocouple temperature difference on both ends of the conductor material and, had nothing to do with hot electrode length and diameter. Structure of armored thermocouple is, is made up of a conductor, high insulation magnesium oxide, coat 1 cr18ni9ti stainless steel protecting tube, after many integrated control. Armoured thermocouple products are mainly composed of terminal block, terminal and armoured thermocouple basic structure, and with various mounting device. Thermal response time: in the phase change temperature, thermocouple output changes to correspond to the step change of 50% of the time required is called thermoelectric armoured thermocouple thermal response response time is not more than the provisions of the table below.
