Pressure Controller for Gases with Integrated Flow Measurement
The electronic red-y smart pressure controller combines the reliable technology of our digital mass flow controllers with electronic pressure control. The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. On-the-fly switching between pressure control and flow control offers maximum flexibility.
- Pressure controller with flow measurement/limitation
- Flow controller with pressure measurement
- Pressure and back pressure devices
- Analog and digital interface
- Options: Multigas, Profibus, built-in display
