Wide Range Vacuum Gauges
BAG302
Description
The INFICON single Bayard-Alpert Hot Ion gauge BAG302 covers a wide measurement range from 1.3 × 10 -9 to 6.7×10 -2 mbar (1 × 10 -9 to 5 × 10 -2 Torr). The compact All-In-One Hot Ion gauge BAG302 offers an easy to exchange dual filament sensor, a built in OLED display, set-point relay and a log-linear analog output as well as an integrated RS485 digital interface for increased integration flexibility. These features combined with the rugged design makes the BAG302 an affordable and repeatable process to base pressure measurement instrument of its own and provides a high value/ low cost of ownership choice.

The INFICON Bayard-Alpert Pirani Combination Gauge, BPG400, functions as two gauges in a single compact unit measuring from 5×10 -10 mbar to atmosphere (3.8×10 -10 Torr to atmosphere). Combining technologies reduces the complexity of installation, setup, and integration. Choose the BPG400 for affordable and repeatable process to base pressure measurements in one economic package. 1) Reduced accuracy during degas 2) Simultaneous use of RS232C or VGC40x controller series and Fieldbus is not allowed 3) For RS232C operation <30m

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 (I 2R) nude ionization vacuum gauge capable of pressure measurement as low as 4×10 -10 Torr. BAG052 and BAG053 are resistive degas (I 2R) glass enclosed ionization vacuum gauges capable of pressure measurement as low as 4×10 -10 Torr. Reliable and...
