Hydrogen Back Pressure Regulator & Flow Controller - red-y Smart

Vögtlin Instruments GmbH

Automatic electronic pressure control with integrated flow measurement
On-the-fly switching between pressure and flow control modes
One device with three operating functions
Multigas capability (up to 10 gases or mixtures)
Profibus and Industrial Ethernet communication options

The red-y smart pressure controller is an advanced electronic pressure controller with integrated flow measurement. It combines reliable thermal mass flow controller technology with electronic pressure control, allowing it to automatically regulate a predefined process pressure while simultaneously measuring and/or limiting the flow rate.
This device offers maximum flexibility by enabling on-the-fly switching between pressure control and flow control. It combines three functions: pressure controller, pressure controller with flow measurement/limitation, and flow controller with pressure measurement. The controller features an inbuilt LED status indication, supports up to 10 different gases or gas mixtures, and is equipped with industrial Ethernet and Profibus interfaces.
It offers a 3-year warranty and high accuracy, with options for various control methods including direct control on the device, via PC with software, or through SPS systems. The device is available in two versions: GSP (pressure control) and GSB (back pressure control), with a wide range of accessories and integration options for seamless use in various industrial applications.

Use Cases

Pressure control of a pressure vessel containing a stable gas mixture for laser gas or welding applications.
Overpressure control of sterile chambers using flow as leakage indicator

Capabilities

Electronic pressure control for gases from 30 mbar up to 10 bar
Integrated thermal mass flow measurement and flow limitation
Back pressure control via reversed valve logic
Multigas operation with real gas calibration
Digital and analog I/O for industrial integration
