Thermocouple and anticorrosive platinum resistance what is the difference between the two temperature gauges _ instrument

Anticorrosion platinum resistance is not now to launch new products, anti-corrosion platinum resistance in anti-corrosion effect, stability and service life of the product has made great progress! 1, the anticorrosion platinum resistance adopts multi-layer ( Anticorrosion thermocouple protection tube coating is usually thick wall 316 l and 904 l steel pipe overall sintered ptfe and wear-resistant anti-corrosion layer) Structure, anticorrosive effect and service life of verified by many domestic enterprises long-term use of the facts. 2, anticorrosive coating of platinum resistance our company adopts advanced ptfe sintering sintering technology with whole, solved the other joint easy to leak problems of manufacturing process is inevitable. The application of this technique to make me the use of anticorrosion thermocouple and other products of the company a long time, in a little wear environment corrosion thermocouple average service life of more than one year. 3, use the site often exist high velocity particles measured medium serious erosion of thermocouple anticorrosive coating company anticorrosive thermocouple in anti-corrosion layer there is a layer of wear-resistant materials, in a environment with scouring can effectively prolong the service life of coating 8 - Ten times, different from other domestic same type anticorrosive sensors. 4, are all made of first-class components, the product performance is stable, reliable, service life is longer than the domestic same type anticorrosive thermocouple several times, can work for a long time at temperature of 220 ℃ or less range. Ordinary thermocouples 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.
