供应Granville-Phillips 354001-YG-T

Granville-Phillips 354 Micro-Ion Vacuum Gauge Module The Granville Phillips Micro-Ion Gauge is the world’s smallest ionization gauge where pressure measurement is based on the amount of ion current that is generated when energized electrons collide with gas molecules in the gauge. High performance in a small volume is achieved through a number of enhancements including its patented dual ion collector design that optimizes electron motion and ion collection. Dual filaments avoid unscheduled downtime since the second filament is used as a backup until the gauge is replaced during a regular maintenace procedure. Ultra-clean construction including vacuum firing of all components and assembly in a Class 100 cleanroom environment, assures rapid, repeatable response during vacuum chamber pumpdown. 

Specifications Filament: yttria-coated iridium Vacuum Connection: 2.75" (NW35CF) Conflat-type Measurement Units: Torr Analog output, no display
