Advantages of S-type platinum rhodium high temperature probe in the industry

The good quality of S-type platinum rhodium high temperature probe is an antidote. It has a great improvement in oxidation resistance and thermoelectric potential stability, but its material is brittle and its welding performance and radiation resistance are poor. Because the thermoelectric performance of the two thermocouple' target='_blank'>thermocouples is almost the same. Therefore, the original nickel-chromium-nickel-chromium thermocouples are gradually replaced by nickel-chromium-nickel-silicon thermocouples. In the current production process, the detection technology and its application are becoming more and more important, especially in the non-destructive abrasion, measurement and measurement of various products and components. The ceramic thermocouple plays an indispensable role in improving quality and corporate Economic benefits are indispensable. The S-type platinum rhodium high temperature probe is composed of nickel-chromium materials and nickel-copper alloy materials, and is represented by the symbol ea. The diameter of thermocouple wire is generally 1.2mm~2mm, nickel-chromium is the positive electrode, and copper is the negative electrode. It is suitable for reducing or neutral medium, the long-term use temperature can not exceed 600℃, and the short-term measurement can reach 800℃. The ea thermocouple is characterized by high thermoelectric sensitivity and low price, but its temperature measurement range is low and narrow, and the copper alloy wire is easily deteriorated due to oxidation. It is also difficult to obtain a uniform wire diameter due to the hard texture of the material. This type of thermocouple can be used in ceramic body dryers, ceramic heat exchangers and other places to obtain more accurate temperature parameters and improve drying and energy saving effects. S-type platinum and rhodium high temperature probes are constantly coming out with special thermocouple products with better functions. For example, tungsten-rhenium thermocouple, it is a kind of better ultra-high temperature thermocouple material, its high use temperature is limited by insulating material, generally can reach the use condition of 2400℃. For example, when measuring with bare wires in a vacuum, higher temperatures can be used. Proud of high-quality functions.
