Test & Measurement

High Vacuum Sensor includes dual filament.

Providing vacuum measurement over range of 1 x 10-10to 1 x 10-2 Torr, 3D Miniature Bayard Alpert Sensor performs similarly to nude ion gauges, but is fully enclosed in protective stainless steel body. Performance at UHV is enhanced by ultra-low X-ray limit. Unit provides faster response times to changes in pressure than glass envelope sensors when close-coupled to vacuum chamber.

Gauge/Controller replaces multiple vacuum gauges.

Incorporating dual sensor technology and controller, self-contained Model CC-10 allows measurement from atmospheric pressure to UHV on single vacuum port. Rough vacuum from atmospheric pressure to 10-2 Torr is measured with crystal sensor, while pressure from 10-2 to 1x 10-9 Torr is measured with double-inverted magnetron cold cathode sensor. Unit includes 0-10 Vdc analog output, RS485 digital...

Glass B/A Ionization Gauge has spring supported filament.
Test & Measurement

Glass B/A Ionization Gauge has spring supported filament.

Designed for accurate measurement over range of 2x10-10-1x10-3 torr, Bayard Alpert Ionization Gauge has universal design that enables use with other B/A controllers. Spring supported filament reduces any variation in filament to grid spacing to deliver uniform output over variations in temperature, age, and orientation. Thoria- or yttria-coated iridium filament minimizes burnout.

Test & Measurement

Cold-Cathode Sensor withstands frequent pressure bursts.

Model 7FC employs double-inverted magnetron technology for wide dynamic vacuum range of 10-2-10-11 torr. Bakeable to 200°C, sensor can be used in any physical orientation. Knife-edge metal seals ensure ultra-high vacuum capability. All wetted materials are 304 stainless and there are no hot filaments to sag and break. Metal-sealed/field cleanable anode subassembly can be maintained without...
