The INFICON Bayard-Alpert passive vacuum gauge heads BAG050, BAG051, BAG052 and BAG053 are designed for use with the INFICON Vacuum Gauge Controller VGC083A & VGC083B. Yttria coated iridium filaments are offered for general vacuum applications in air and inert gases such as N2 and argon. Select tungsten filaments for gases that are not compatible with yttria coated iridium filaments. BAG05x gauges may also be operated with compatible vacuum gauge controllers from other manufacturers. The INFICON passive Bayard-Alpert ionization vacuum gauges (BAG05x) are offered in three different configurations:
BAG050 is a EB-degas UHV nude ionization vacuum gauge capable of pressure measurement as low as 2×10-11 Torr.
BAG051 is a resistive degas (I2R) nude ionization vacuum gauge capable of pressure measurement as low as 4×10-10 Torr.
BAG052 and BAG053 are resistive degas (I2R) glass enclosed ionization vacuum gauges capable of pressure measurement as low as 4×10-10 Torr.
Reliable and proven gauge head design
Drop in for most nude hot ion gauge heads
Wide range of emission currents (100 μA to 10 mA)
Available with single / dual yttria coated iridium and dual tungsten filament cathode assemblies
Degas: All models can be degased using EB (electron bombardment).
BAG051, BAG052 and BAG053 can also be degased using resistive degas (I2R)
