Heraeus Electro-Nite launched Chameleon Foundry in 2025, an automated system for measuring temperature that uses fibre-optic technology. Drawing on many years of expertise in measurement solutions, the company provides a wide range of sensors and accessories designed to support precise control of metallurgical processes. These include tools for monitoring temperature, oxygen, carbon content, and other key quality parameters in molten metal.
Iron Foundries Achieve Precise Temperature Control Without Single-Use Sensors
Chameleon Foundry introduces a new approach to measuring the temperature of molten iron. Instead of relying on traditional single-use temperature probes, the system employs a durable fibre-optic cable that enables direct measurement within the melt. It was designed specifically for use in iron foundries, with a strong focus on precision, reliability, and process safety.
In contrast to conventional techniques, where operators manually insert probes into ladles or pouring channels, measurements can now be initiated either fully automatically through PLC-controlled signals or manually at the push of a button from a control interface.
Once activated, the system automatically lowers the fibre-optic probe into the melt, captures temperature data, and transmits the results in real time. This approach also reduces operator exposure to hazards such as extreme heat and molten metal splashes.
Enhanced Operational Efficiency While Significantly Lowering Consumable Demand
Compared to conventional measurement methods that rely on disposable thermocouples, additional effort is required for maintenance, along with higher logistics and storage expenses. These systems also generate considerable material costs, since the used thermocouples must be discarded as waste after each measurement. In contrast, Chameleon Foundry’s FIMT (Fibre in Metal Tube) technology is designed to dissolve directly in the melt.
When used at high-frequency or critical measurement points, this approach can significantly reduce operational effort. A single 25-kilogram coil can support up to 6,000 measurements and replaces multiple pallets of traditional sensors. This leads to lower storage requirements, reduced transportation costs, and a smaller environmental impact.
Eliminating components such as cardboard tubes also helps reduce material consumption and waste, contributing to more sustainable foundry processes. In addition, fewer parts need to be replaced over time, which reduces maintenance demands, improves system availability, and minimizes the risk of unplanned downtime.
Greater Workplace Safety for Operators and Technical Staff
One of the main advantages of this new technology is the improvement of workplace safety. In industrial environments where workers are exposed to extreme temperatures, radiant heat, molten metal, and potential splashing, manual operations can present significant hazards.
By enabling fully automated immersion measurements based on fibre-optic technology, the system eliminates the need for direct human contact with the melt. This reduces the likelihood of accidents and helps establish safer and more controlled working conditions.
Higher Product Quality Through Streamlined Process Optimisation
Automated control systems make it possible to achieve more consistent and precise measurements, as they are performed under identical conditions each time. This consistency helps improve casting quality, reduce energy usage, and reach target temperatures more reliably. As a result, issues such as overheating, unnecessary energy consumption, and the need for rework can be minimized.
Overall, this leads to more stable production processes and better-optimized energy efficiency, supporting consistently high product quality in iron casting manufacturing.
