Page 28: Operation
4 Operation 4.1 Measuring Principle, The BPG400 vacuum gauges consist of two separate measuring systems (hot cathode Bayard-Alpert (BA) and Pirani). Measuring Behavior Bayard-Alpert The BA measuring system uses an electrode system according to Bayard-Alpert which is designed for a low x-ray limit. -
Page 29: Operational Principle Of The Gauge
The bridge voltage U is a measure for the gas pressure and is further processed electronically (linearization, conversion). Measuring range The BPG400 gauges continuously cover the measuring range 5×10 mbar … 1000 mbar. · The Pirani constantly monitors the pressure. -
Page 30: Degas
700 °C by electron bombardment. Depending on the application, this function can be activated manually by a switch or automatically by the system control via a digital interface. The BPG400 automatically terminates the degas process after 3 minutes, if it has not been stopped before. -
