Improved Glass B/A and Nude Ionization Gauges Available in Any Pin Configuration for Use with Any Manufacturer's B/A Controller

Televac/ETI, a leading ISO9001:2000 manufacturer of UHV measurement sensors, filaments, glass-to-metal seals and feedthroughs, has announced availability of their expanded line of Glass B/A and Nude Ionization Gauges in any pin configuration for use with any manufacturer's B/A controller.

Glass Bayard-Alpert Gauges are designed and engineered to provide highly accurate measurement over a range of 2 x 10-10 to 1 x 10-3 torr, while our special broad range gauge measures 1 x 10-10 to 1 x 10-1 torr. Gauges are constructed with a bi-filer grid and thoria or yttrium coated iridium filament to minimize burnout for longer filament life. The interior of the tube can be platinum coated to shield gauge components from electrostatic and static charges that can occur in various operating conditions. A variety of glass or metal tabulation and flange end configurations are available to suite application requirements.

Nude Ionization Gauges provide highly sensitive measurement over a range of 2 x 10-11 to 1 x 10-3 torr, and feature a bi-filer grid and replaceable thoria-coated dual Tungsten or single iridium filaments. A .005" diameter collector provides a low x-ray limit sensitive tube that can be baked out to 450ºC for applications requiring high temperature processing.
