WebIdeal Vacuum Vacuum Pumps, Vacuum Chambers, and Pump Repair The hot-filament ionization gauge, sometimes called a hot-filament gauge or hot-cathode gauge, is the most widely used low-pressure (vacuum) measuring device for the region from 10 to 10 Torr. It is a triode, with the filament being the cathode. Note: Principles are mostly the same for hot-cathode ion … Meer weergeven A regulated electron current (typically 10 mA) is emitted from a heated filament. The electrons are attracted to the helical grid by a DC potential of about +150 V. Most of the electrons pass through the grid and collide with … Meer weergeven • Bayard–Alpert (uses sealed tube). • Nude gauge (uses the vacuum chamber to make a complete seal).

In normal usage, a gauge is a particular choice, or specification, of vector and scalar potentials A and ϕ which will generate a given set of physical force fields E and B. More specifically, a physical situation is specified by the electric and magnetic fields, E and B. A set of potentials A and ϕ generates the force fields if it obeys ... simplehuman cabinet mount trash can
