that of atmospheric pressure. there are several types of vacuum gauges, each engineered for a specific function over a specific range of vacuum pressure (fig. ). common types (table ) include: mechanical gauges absolute pressure gauges thermocouples or pirani gauges ionization gauges (hot & cold cathode

gauge head to the readout. gauge heads are usually mounted vertically, i.e. with the connection downwards. this is to allow the gauge heads to read correctly and also to prevent debris from entering the head. for systems such as vacuum furnaces the high vacuum gauge most used is the penning cold cathode...

are encountered. the source of the free conduction electrons in the device may be either thermal such as a heated filament physically associated with the cathode of the device - a hot cathode, or alternatively a simple consequence of a high voltage gradient across the device, resulting in autoemission

from the cathode. a device employing this latter method is known as a cold cathode device. in high voltage switching the presence of high voltages, and hence the possibility of large voltage gradients within devices means that the cold cathode system, quite a rarity in most other types of tubes, is...
