640B Integrated Absolute Pressure Controllers
Overview
The 640B absolute pressure controller is a self-contained, compact, closed-loop electronic pressure control system containing a Baratron® capacitance manometer, normally closed proportioning control valve, and closed-loop control electronics. Electrically similar to a standard MFC, the 640B is powered by ±15 VDC at only 200 mA, permitting use with standard power supply and display electronics. The pressure output and input control signals are linear 0-5 or 0-10 VDC. Two trip points with LED status indicators are for use as simple on/off process limits.
- Integrated Baratron® capacitance manometer technology
- Full Scale ranges as low as 10 Torr for low pressure processes
- Can be used with upstream or downstream controller applications
- Two alarm trip points for process limit control
