High Stability Gauges Selected ETI gauges can be ordered with high stability "S" option. These gauges are manufactured with a spring-tensioned, burn-out resistant, thoriated iridium filament, improved supports, and gold-plated connector pins. This improved design significantly reduces any variation in the filament to grid spacing which, in turn, affects gauge sensitivity. Filament sag is totally eliminated and allows the user to mount the gauge in any position. Special materials are also used to minimize or eliminate ESID. The resultant benefit is a gauge that has double the useful life over the traditional gauges. Erroneous pressure readings due to physical/sensitivity changes are eliminated. Gold-plated pins assure that the gauge tube can be easily removed from the connector after extended use. The improved "S" gauges can be used with all manufacturers' gauge controller electronics and, in turn, will improve system measurement stability and accuracy without having to invest in a new gauge controller.   Flux Monitor (shown bottom, left) The Flux Monitor is a variant of the ETI 8130 Nude Ionization Bayard-Alpert gauge. Its unique construction positions the ionization gauge further into the chamber to avoid "wall-effect outgassing". This phenomenon is especially prevalent in large chambers that are frequently exposed to atmosphere or which are used with gases that tend to be adsorbed to the chamber. Wall- effect error can add up to two decades of pressure error. This error can adversely affect product quality. The Flux Monitor Gauge is custom built to your length requirements.
