red-y smart pressure controller – Productinfo

Digital Pressure Controllers for Gases with integrated Flow Measurement

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

Instrument Versions

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

It‘s a red-y smart

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

Analog & Digital

The pressure controllers make use of the latest CMOS technology and have a digital (Modbus RTU) and analog interface as standard*.

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

* analog output for actual value flow only

Operating Status Indication

The instruments offer a built-in LED status indication
