Currently the trend changes, to control furnaces completely with PLC without special control devices.
We take this into account with the sensor module which enables nitriding potential control and online calculation of carbon diffusion at PLC level.
The device is suitable for integration in PLC controls for new systems or modernizations, but also for retrofitting in existing controls with conventional controllers.
- Sensor module for top hat rail mounting
- Available in different versions:
-> as a module for connecting an oxygen probe
-> as a module for connecting an oxygen probe with C level calculation
-> as a module for connecting an oxygen probe with C level calculation and
carbon diffusion calculation with target point control and graphical display of the carbon diffusion profile via webserver
Carbon diffusion profile
-> as a module for connecting a hydrogen sensor and an oxygen probe for nitrier- und nitrocarburizing processes with KN / KC / KO – calculation and grafischer display of the Lehrer diagram and the Kunze diagramms via webserver
