Platinum Rhodium Wire Type B Thermocouple Bare Wire Pt-Rh Recycling

Introduction:

Type B thermocouple bare wire is a commonly used thermocouple temperature measurement device, widely used in industrial fields and laboratory environments. It consists of two alloy wires of different metals and measures temperature changes through the thermoelectric effect.

The structure of type B thermocouple bare wire is relatively simple. It consists of two alloy wires of different metals. One end of the two wires is connected together to form a measurement point, and the other end is connected to a temperature measurement device, such as a temperature transmitter or data sensor. Acquisition System. Type B thermocouple bare wire usually uses platinum-rhodium alloy wire (platinum 90%, rhodium 10%) and platinum-rhodium alloy wire (platinum 94%, rhodium 6%) as thermocouple materials. This combination has high accuracy. and stability. Platinum, rhodium and their alloy materials have become a classic thermocouple material in modern industry due to their unique physical and chemical properties. They have high temperature measurement accuracy, wide range and easy use. They are widely used in metallurgy, petrochemical industry, glass fiber, It is widely used in electronic industry, aerospace and other fields. It has good thermoelectric properties and thermoelectric potential stability and high precision; it can be used to make various types of thermocouples used at 0℃-1800℃.

During the temperature measurement process, the measuring point of the Type B thermocouple bare wire is exposed to the environment to be measured, and temperature changes will cause a slight potential difference between the alloy wires. There is a specific relationship between this potential difference and temperature, known as the thermoelectric effect. By measuring this potential difference, the temperature of the environment can be accurately calculated.

Type B thermocouple bare wire has many advantages, such as a wide temperature measurement range (usually from 0 degrees Celsius to 1820 degrees Celsius), higher accuracy and reliability, and faster response time. It also has good corrosion resistance and low thermocouple resistance drift, making it suitable for applications requiring high accuracy and long-term stability.
