SM 01 Sensor module
The current trend is to map furnace controls completely with PLCs without special control devices.
We are taking this into account with the sensor module presented here and enabling nitriding ratio control and online calculation of carbon diffusion at control level.
The device is suitable for integration in PLC control systems for new systems or modernizations, but also for retrofitting in existing control systems with conventional controllers.
Description of funtion
Functions
The sensor module enables nitriding ratio control and online calculation of carbon diffusion at control level as well as carbon diffusion calculation with target size control and graphical display of the carbon diffusion profile via web server.
