Thermocouple and assembly thermocouple what is the difference between the two temperature gauges _ instrument

Thermocouple is a kind of temperature sensor, it is smaller than the diameter of a prefabricated thermocouple, flexible, good vibration resistance, suitable for installation in the case of prefabricated thermocouple can't install, the company produces the thermocouple used to introduce thermocouple temperature measuring element, therefore, is accurate, sensitive, fast thermal response time, stable quality, long service life, etc. Thermocouple temperature measuring instrument is commonly used in temperature measuring element, is made up of two different components of the conductor when two ends synthesis loop, when the two junction thermocouple temperature is not at the same time, will produce thermal current in the circuit. If the work end of the thermocouple with the reference entity temperature difference, display instrument will indicate the thermocouple thermoelectric potential of the corresponding temperature value. Thermocouple assembly is industrial thermocouple as the temperature measurement sensor assembly, usually display instrument, recorder and electronic regulator, etc, it can be directly measured or control - all kinds of production process 200℃- 600 ℃ range of liquid, steam and gas medium, as well as the temperature of the solid surface. The characteristics of the thermocouple assembly pressure reed temperature sensing element, ant-vibration performance is good; High precision temperature measurement; High mechanical strength, good compression performance; Imported film resistance element, reliable performance and stable although thermocouple is widely applied in industry, but because of his temperature range makes his application by certain restrictions, thermocouple temperature measurement principle is based on a conductor or semiconductor resistance changes with the change in temperature. Its many advantages, can also remote transmission signal, high sensitivity, strong stability, compatibility and accuracy are better, but you need to power, can't instantaneous measured the change in temperature. Industrial thermocouple usually use Pt100, Pt10, Cu50, Cu100, platinum thermocouple temperature measurement range is generally 200 - below zero 800 ℃, copper thermocouple is 40 to 140 ℃ below zero. As to distinguish the type of thermocouple and thermocouple compensation wire, but it does not need and is cheaper than thermocouple.
