Baratron® 45°C Heated 0.05 to 1000 Torr Isolation System
Baratron® 45°C Heated 0.05 to 1000 Torr Isolation System
The CV7627H Isolation System is designed to automatically maintain a 45°C heated 627H Baratron® capacitance manometer at vacuum throughout a process cycle. Maintaining a heated Baratron® capacitance manometer at vacuum is one of the most important ways to optimize its accuracy and repeatability in production systems, making this product especially well-suited for fast-cycling industrial and semiconductor manufacturing processes.

CV7627 System Components
The Isolation System consists of a 627 45°C heated process Baratron® capacitance manometer, a Pneumatic Isolation Valve, and an R750 Mini-Baratron® capacitance manometer with Relay Module. The R750 Relay Module monitors the process pressure, and provides a contact closure that is used to open or close a (customer-supplied) solenoid in the pneumatic line to the Pneumatic Isolation Valve. This solenoid closes the valve whenever the process pressure exceeds the Full Scale range of 627 Baratron® capacitance manometer, maintaining it in its optimum working range. Many different Baratron capacitance manometer configurations and trip point options are available.
