Den mittlerweile allgegenwärtigen PC kann man nutzen, kostengünstig zeitliche Druckverläufe (Auspumpkurven, Prozeßkurven etc.) aufzuzeichnen, zu analysieren und zu dokumentieren. Vorgestellt wird hier ein neu entwickeltes Vakuum-Meßgeräte-Konzept mit der zugehörigen Windows-Auswerte-Software. Die erste beschriebene Meßgeräte-Gruppe umfaßt kompakte...

Since almost 100 years Pirani gauges based on the principle of heat-conduction are used for measuring absolute pressure in the fine vacuum range. In most cases a steadily operated sensor in a controlled bridge circuit is used where its filament is kept on constant temperature. Above certain pressures this principle shows a strong saturation effect...

Minimaler Leistungsverbrauch, erweiterter Messbereich, verbesserte Auflösung, hervorragende Stabilität, digitale Abgleichmöglichkeit, verringerte Baugröße: Dies sind, kurz zusammengefasst, die erstaunlichen Merkmale des soeben als Weltneuheit vorgestellten Pirani-Vakuum-Transmitters. Minimum power consumption, enlarged measurement range, improved...

Gas concentration monitoring is essential in industrial or life science areas in order to address safety-relevant or process-related questions. Many of the sensors used in this context are based on the principle of thermal conductivity. The 3ω-method is a very accurate method to determine the thermal properties of materials. It has its origin in th...

Zero‐pressure” elimination with Pirani principle for vacuum measurement and increase of the measurement range limit of thermal gas‐sensors and flow sensors Measurement of pressure in the medium vacuum range has been done via thermal conductivity. The literature on the Pirani principle has defined a lower range limit — the so‐called “zero pressure”...
