Proportional flow controller OF series

closed-loopfor gasfor oxygen

Overview
The Open Frame proportional controller (Series OF) is a modular system for proportional control of pressure, flow and position. The system is composed of two base modules: Head and Expansion. The Open Frame Controller can be configured to provide turnkey solutions, reducing assembly times and system complexity. The different Head and Expansion modules can be combined and driven through simple serial communications. The platform provides closed loop control of flow, pressure and position and is suitable for Industry 4.0 applications.

Key features

• Closed loop flow control
• Compatible to be used with oxygen (specific cleanliness level options)
• Composed of two base modules:
  • Head
  • Expansion
• Customised, turnkey solutions
• Interfaces: Analog, CANopen or IO-Link

Applications
Typical applications include mixing of different gases and piloting different pressures in different parts of a machine. Suitable sectors: assembly and robotics, automotive production, electronics, food processing and packaging, life science, machine tools & manufacturing systems, paper & printing, plastic & rubber, textile, woodworking, glass industry and more.
