BAG055 Hot Ionization Gauges

Mini hot ion Bayard-Alpert passive gauge head for VGC083

The hot cathode ionization passive vacuum gauge head BAG055 is a miniature, metal enclosed Bayard-Alpert sensor designed for use with the Vacuum Gauge Controller VGC083A. BAG055 is an electron bombardment (EB) degas metal enclosed hot ionization vacuum gauge capable of pressure measurement down to 1×10-9 mbar. 

Thanks to its compact size and a large selection of possible flanges and fittings, BAG055 can be installed in every vacuum system easily and with minimal footprint.

BAG055 is offered with a dual yttrium oxide coated iridium filament and can be baked up to 200 °C. The high accuracy (15%) makes BAG055 a cost effective and robust choice for general vacuum industrial or R&D applications.
