Thermocouple and wear-resistant thermocouple what is the difference between the two temperature gauges _ instrument

Wear-resistant thermocouple as well as wear-resistant thermocouple are power plants circulating fluidized boiler, boiling boiler, coal mill powder gasification furnace and a series of cement kiln head, preheater, furnace hood and chemical, smelting, such as high temperature wear conditions are ideal for high tech products, wear-resistant thermocouple eclecticism, adopt unique craft formula, the product produce wear-resistant alloy in the gaffe balance with ordinary stainless steel metal, metal ceramic protection tube, compared with the similar wear-resistant alloy protection tube on the market, and increase its service life 5 times. Due to environment temperature difference, high temperature control point, the vibration is larger, blower wind speed is too high, serious wear and tear, caused the temperature measurement is very difficult, life is very short, only 10 - general wear-resistant alloy 90 days to grind through damage, burn bent, broken, damaged thermocouples, bring great damage to the user and unnecessary trouble, wear-resisting type thermocouple made up for this shortcoming. From the thermocouple temperature measurement principle, the measured the change in temperature is directly measured by thermocouple resistance change, therefore, the wires of a thermocouple body such as a variety of wire resistance change will affect temperature measurement. Thermocouple is by thermal components ( The resistor body) , wire, insulation materials, stainless steel casing combination solid body, its diameter is generally from 2 to 8 mm, achieve more xiaoke phi is 0. 25mm。 Compared with conventional type thermocouple, it has the following advantages: (1) small volume, no internal air gap, thermal inertia, the measured value after small; (2) good mechanical properties, resistance to vibration and shock. (3) can bend, easy to install (4) long service life. 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 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.
