NIR pyrometer SPOT+ MM

visual°C°F

The smart SPOT+ MM (MeltMaster) application pyrometer provides a single-sensor solution for liquid metal temperature measurements in foundry and tapping applications. Optimised signal processing and a dedicated application mode allow the SPOT+ MM to accurately measure tapping stream temperatures independent of surface and condition changes during the process. The SPOT+ MM has millisecond responsivity with integrated time functions to monitor and hold the tapping temperature for a configured time or until the next tapping process starts. Multiple digital and analog interfaces enable easy integration into new and existing process control systems. An internal visual camera aids alignment and provides a remote process view via the integrated webserver of the SPOT+ MM. The webserver and Modbus TCP/IP enable full remote access to the pyrometer without the need for any additional software. The SPOT+ MM is compatible with the SPOT Actuator for alignment with moving or multiple tapping streams. A further range of accessories, including the industrial enclosure with cooling and air purging options, allow the SPOT+ MM to work in harsh environmental conditions 24/7. FUNCTIONALITY In foundry tapping applications, pouring stream conditions are typically not stable. As the liquid metal surface changes during the pouring process, and an initial thin variable oxide layer is established, a special pyrometer is needed to accurately measure the liquid metal temperature and obtain the most accurate and continuous readings.
