red-y smart pressure controller

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

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.
