Description
Verfahren für die magnetische Sauerstoffmessung Der Erfindung liegt die Aufgabe zugrunde, die i7mpfindl ichkeit der magnetischen Sauerstoffanalyse zu erhöhen. Das ist z. B. wichtig für die ltauchgasanalyse auf Sauerstoff, da man für gute Feuerungen immer möglichst kleinen Luftüberschuß anstreben wird, also kleine Meßbereiche wünscht. Ferner ist die Erhöhung der Empfindlichkeit dieser Geräte für Sonderfälle in der chemischen Industrie, z. B. für Katalysatorregenerierung bei der Bunaherstellung, sehr wichtig.Procedure for magnetic oxygen measurement The invention lies the underlying task is to increase the sensitivity of the magnetic oxygen analysis raise. This is e.g. B. important for the analysis of the immersion gas for oxygen, because one for good furnaces will always aim for the smallest possible excess of air, i.e. small ones Desires measuring ranges. It also increases the sensitivity of these devices for Special cases in the chemical industry, e.g. B. for catalyst regeneration the Buna production, very important.
Der Erfindung liegt die Erkenntnis zugrunde, daß die Empfindlichkeit des magnetischen Sauerstoffmessers etwa verdoppelt werden kann, wenn man nicht nur den magnetischen Wind als Meßgröße für den Sauerstoff verwendet, sondern auch die Wärmeleitfähigkeit des Sauerstoffs und beide Effekte sich addieren läßt. Diese Forderung wird dadurch erfüllt, daß die beiden Meßkammern mit Meßgas und die beiden Vergleichskammern mit einem konstanten Gas, z. B. Luft, belüftet werden. The invention is based on the knowledge that the sensitivity of the magnetic oxygen meter can be roughly doubled, if not only uses the magnetic wind as a measure of the oxygen, but also the Thermal conductivity of oxygen and both effects can be added. This requirement is fulfilled in that the two measuring chambers with measuring gas and the two comparison chambers with a constant gas, e.g. B. air, ventilated.
Bei den bekannten Sauerstoffmessern wurden alle vier Kammern mit dem Meßgas belüftet. Der Effekt der Wärmeleitänderung des Gases fiel also heraus, gemessen wurde nur die Abkühlung der Systeme infolge des magnetischen Windes. In the known oxygen meters, all four chambers were with vented to the measuring gas. The effect of the change in thermal conductivity of the gas fell out, only the cooling of the systems as a result of the magnetic wind was measured.
Belüftet man aber gemäß der Erfindung lediglich die Meßkammern mit dem Meßgas und die Vergleichskammern getrennt mit einem konstanten Gas, z. B. Luft, so mißt das Gerät auch den Effekt der Wärmeleitänderung des Meßgases, ähnlich wie der bekannte C O2-Messer. Da nun der magnetische Wind eine Abkühlung der Meßsysteme bei steigender O2-Konzentration herbeiführt und die erhöhte \Märmeleitfähigkeit des Sauerstoffs ebenfalls, so addieren sich die beiden Effekte und bewirken dadurch eine erhöhte Empfindlichkeit des Gerätes auf Sauerstoff. Anzuwenden ist die Erfindung bevorzugt bei der Rauchgasanalyse und bei der technischen 02-Analyse bei hohen Empfindlichkeitsforderungen. However, according to the invention, only the measuring chambers are ventilated the measurement gas and the comparison chambers separated with a constant gas, e.g. B. air, so the device also measures the effect of the change in thermal conductivity of the measuring gas, similar to the well-known C O2 meter. Since now the magnetic wind is cooling down the measuring systems with increasing O2 concentration and the increased \ Fair conductivity of the oxygen as well, then the two effects add up and cause an increased sensitivity of the device to oxygen. The invention is to be applied preferred for flue gas analysis and technical 02 analysis with high sensitivity requirements.
