Platinum rhodium wire is a key component in thermocouples and an important element for temperature measurement. So where is the position of the platinum rhodium wire in the thermocouple?

Platinum rhodium wire is usually located at the measurement end of thermocouples. Due to its excellent conductivity and high-temperature oxidation resistance, platinum rhodium wire can ensure measurement and long-term stability. At the same time, due to the working principle of the thermocouple, the temperature at the measuring end is the same as the temperature of the measured object, so the contact between the platinum rhodium wire and the measured object is also very important.

 

In summary, the platinum rhodium wire on the thermocouple is located at the measurement end to ensure stability and close contact with the measured object, achieving temperature measurement.


Platinum rhodium wire on thermocouple

A thermocouple is a temperature measuring device based on the principle of the "thermoelectric effect", consisting of two different metal rods connected together to form a circuit. Among them, one rod is called the reference temperature point, and the other rod is the measurement temperature point. At the measurement end of the thermocouple, platinum rhodium wire is an important component. So what are the functions and characteristics of platinum rhodium wire?

Firstly, platinum rhodium wire is one of the core devices of thermocouples, and due to its excellent conductivity and high-temperature oxidation resistance, it can ensure measurement and long-term stability. Secondly, platinum rhodium wires are generally placed at the measurement end of thermocouples, in direct contact with the measured object to achieve temperature measurement of the measured object.

 

In addition, platinum rhodium wire also has a high melting point and low resistivity, making it less prone to melting and burning, and has a good linear relationship at high temperatures, which can meet the requirements of high, high temperature and long-term measurement.

 

In summary, platinum rhodium wires play an important role and feature in thermocouples. It is a key component for ensuring thermocouple measurement and stability, and also an important element for achieving temperature measurement of the measured object
