red-y smart pressure controller
Attribute:
The electronic red-y smart pressure controller combine 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.

1 Device – 3 Functions
The pressure controller combines three functions:
- Pressure controller
- Pressure controller with flow measurement/limitation
- Flow controller with pressure measurement
The following instrument versions are available:
- Integrated pressure control
Accuracy:± 0.5 % of full scale - Integrated back pressure control
Accuracy:± 0.5 % of full scale - Pressure control with external pressure transmitters
- Pressure controller with gas mixer function
Analog & Digital: 2 in 1
The pressure controllers make use of the latest CMOS technology and have a digital (Modbus RTU) and analog interface as standard.Profibus, Profinet RT and EtherCAT interfaces are available.
A wide range of cables and power supply units for fast integration of the red-y smart pressure controllers is available:
