Advantages of S-type Platinum Rhodium High Temperature Probe in the Industry

The S-type platinum rhodium high-temperature probe has good quality and is a remedy, with significant improvements in oxidation resistance and thermoelectric stability. However, its material is brittle and its welding performance and radiation resistance are poor. Due to the almost identical thermoelectric performance of the two thermocouples. Therefore, the original nickel chromium nickel chromium thermocouple has gradually been replaced by nickel chromium nickel silicon thermocouple. In the current production process, detection technology and its application are becoming increasingly important, especially in non-destructive scratching, measurement and metrology of various products and components. Ceramic thermocouples play an indispensable role in improving quality and economic benefits of enterprises.

The S-type platinum rhodium high-temperature probe is composed of nickel chromium material and nickel copper alloy material, represented by the symbol ea. The diameter of thermocouple wires is generally 1.2mm to 2mm, with nickel chromium as the positive electrode and copper as the negative electrode. Suitable for reducing or neutral media, long-term use temperature cannot exceed 600 ℃, short-term measurement can reach 800 ℃. The characteristics of EA thermocouples are high thermal sensitivity and low cost, but their temperature measurement range is low and narrow, and copper alloy wires are prone to deterioration due to oxidation. Due to the hard texture of the material, it is not easy to obtain a uniform wire diameter. This type of thermocouple can be used in ceramic body dryers, ceramic heat exchangers, and other places to obtain more accurate temperature parameters, improve drying and energy-saving effects.

Special thermocouple products with better functionality of S-type platinum rhodium high-temperature probes are constantly emerging. Like tungsten rhenium based thermocouples, it is a good material for ultra-high temperature thermocouples. Its high operating temperature is limited by insulation materials and can generally reach 2400 ℃. When measuring with bare wire in vacuum, higher temperatures can be achieved Proud of its high-quality features.
