red-y smart pressure controller ā€“ Productinfo

DigitalĀ Pressure Controllers for Gases with integrated Flow Measurement

The electronic red-y smart pressure controller combine the reliable technology of our digitalĀ 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.Ā On-the-fly switching between pressure control and flow control offers maximum flexibility.

1 Device ā€“ 3 Functions

Ā The pressure controller combines three functions:

  • Pressure controller
  • Pressure controller with flow measurement/limitation
  • Flow controller with pressure measurement

Instrument Versions

Integrated pressure control
Accuracy:Ā± 0.5 % of full scale

Integrated back pressure control
Accuracy:Ā± 0.5 % of full scale

Pressure control with external pressure transmitters

Pressure controller with gas mixer function

Itā€˜s a red-y smart

The pressure controllers combineĀ the innovative equipment design of the red-y smart series with the development competence of Vƶgtlin Instruments AG.
High-quality components ensure long and trouble-free operation.

Analog & Digital

The pressureĀ controllers make use of the latest CMOS technology and have aĀ digitalĀ (Modbus RTU) andĀ analog interface as standard*.

Profibus interfaceĀ is available as option (Profibus DP-V0/DP-V1).

* analog outputĀ for actual value flow only

Operating Status Indication

The instruments offer a built-in LED status indication
