8793 Process controller
Digital electropneumatic process controller
- Compact and robust design
- Easy Start-up using tune function of the positioned and process controller
- Integrated diagnostic functions for valve monitoring
- Dynamic positioning system with no air consumption in controlled state
- Optimized for high-pressure proportional valves MPG and HPG
- Version for quarter-turn actuators (NAMUR) available
The robust and compact Bürkert process controller has been tailored for m-tech proportional valves with a remote stroke sensor. The process controller is equipped with additional diagnostic functions to monitor the state of the valve. Operation is done via the external operation and display module with a backlit graphical display.
