WebETI BAYARD ALPERT GAUGE MANUAL REV - Page 6 of 11 4.0 TECHNICAL INFORMATION 4.1 PRESSURE INDICATION Ionization gauge controllers actually measure the positive ion current in amperes from the gauge tube but the readout is in pressure units. Even more specifically, these pressure units are direct reading only for the gas WebThe combination of a hot cathode ionisation sensor (utilising the Bayard Alpert method of hot cathode ionisation) and a Pirani sensor enables vacuum pressure measurements from 5 . 10 -10 to 1000 mbar (3.75 . 10 -10 to 750torr). Two main variants are available: ITR 90 with single hot cathode filament
WebThe Agilent 571 Bayard-Alpert gauge offers high performance over a pressure range of 2 x 10 -10 to 1 x 10 -3 Torr (2.6 x 10 -10 to 1.33 x 10 -3 mbar). The 571 gauge withstands long periods of degassing or accidental exposure to atmospheric pressure while at operating temperature and will still recover its original characteristics. WebPirani/Bayard-Alpert combination HPT 200 (5 · 10-10 – 1000 hPa) The HPT 200 gauge enables accurate measurements from 5 · 10 -10 hPa to atmospheric pressure. With its rugged metallic case and the digital interface, this gauge is especially suitable for operation in vacuum and other systems.
WebThe Bayard-Alpert gauge’s collector current was a linear function of vacuum, while the cold cathode sensor was non-linear. The Bayard-Alpert readouts had linear meter scales and offered better resolution than the non-linear cold cathode meter scales. WebOct 27, 2024 · UHV-24 Bayard-Alpert Ion Gauge Tube The Agilent UHV-24 and UHV-24p Bayard-Alpert ion gauge tubes have wide ranges of operating pressure capabilities. The UHV-24 can measure pressures below 2 x 10 -11 Torr (2.7 x 10 -11 mbar), while the UHV-24p can measure pressures below 5 x 10 -12 Torr (6.7 x 10 -12 mbar).
WebBayard-Alpert style gauges have become the standard for accurate measurement of vacuum in mass spectrometers. In some instances, a mass spectrometer may be shipped without a vacuum gauge since it is an optional accessory (such as in the Hewlett Packard 5971 Mass Spectrometer). The mass spec user can easily add the controller at a cost ...
