Method of Removing Platinum Rhodium Wire from Industrial Thermocouples

Industrial thermocouple is a device commonly used for measuring temperature, which is composed of different thermosensitive elements, among which platinum rhodium wire is one of the common materials. Removing platinum rhodium wires from industrial thermocouples requires certain skills and methods. Below are two commonly used removal methods.
1. Cutting method
The shearing method is a simple method suitable for situations where the contact between the platinum rhodium wire and other components is loose, or the platinum rhodium wire has been damaged without the need to preserve its integrity.
Fix the industrial thermocouple on a flat workbench to ensure its stability.
Use electrician scissors or wire cutters to cut the platinum rhodium wire.
Put the removed platinum rhodium wire into a storage container, being careful not to come into contact with other metals to prevent electrochemically induced reactions.
2. Unsoldering method
The desoldering method is suitable for situations where the integrity of the platinum rhodium wire needs to be preserved and continued to be used, which is relatively complex and requires certain welding skills.
Fix the industrial thermocouple on the welding table to ensure its stability.
Use a welding gun or other suitable welding tools to preheat the solder to the appropriate temperature.
Apply the preheated solder evenly to the platinum rhodium wire solder joints.
Heat the solder joint using a welding tool until the solder melts, and gently remove the platinum rhodium wire.
Put the removed platinum rhodium wire into a storage container, taking care to avoid contact with other metals to prevent electrochemically induced reactions.
Removing the platinum rhodium wire from industrial thermocouples is a process that requires careful handling. Regardless of the method used, safety must be taken into consideration to avoid secondary damage to the thermocouple and platinum rhodium wire. At the same time, after dismantling, it is necessary to store the platinum rhodium wire correctly to ensure its quality and effective service life.
The platinum rhodium wire in industrial thermocouples can be removed through two methods: cutting and desoldering. The cutting method is suitable for situations where the platinum rhodium wire is relatively loose or damaged, and the operation is simple; The desoldering method is suitable for situations where the integrity of the platinum rhodium wire needs to be preserved and continued use, and the operation is relatively complex. During the dismantling process, it is essential to pay attention to safety and store the platinum rhodium wire correctly to ensure its quality and service life.
