Product catalog summary
Overview
The document describes the OXYTRANS M, a portable optical oxygen sensor designed for measuring O2 in various liquids and gases such as deaerated water, wort, beer, beverages, liquid food, CO2, and protective gases. It is engineered for applications requiring high sensitivity and accuracy.

Measurement Technology
The sensor operates on the principle of radiationless energy transfer through molecular interaction. It uses a small glass component with indicator molecules that absorb blue-green light from an LED, transitioning to a higher energy state. When these molecules return to their ground state, they emit red light, which is detected by the sensor. The presence of O2 molecules affects the energy transfer, reducing the detected signal as O2 concentration increases. Other gases do not impact the measurement.

OXYTRANS M-1

The Process Technology Company. Portable Optical O2 Measurement in Liquids and Gases Tragbare optische O2 Messung in Flüssigkeiten und Gasen OXYTRANS M is a portable optical oxygen sensor for measurement of O2 in e. g. deaerated water, wort, beer, beverages, liquid food, CO2 and protective gases. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. The measurement technology is based on the radiationless redistribution of excitation energy via molecular interaction. In the measuring head a small glass component with a thin layer of indicator molecules is installed, the optical window. The indicator molecules are illuminated with blue-green light produced by an LED in the sensor. They absorb the incident light and are promoted to a higher energy state. After a certain time the molecules convert back to their ground state, during which red light is emitted. The red light is detected inside in the sensor. If O2 molecules are present the energy is transferred from the excited indicator molecules to the oxygen. The detected signal decreases with increasing concentration of O2 molecules in the product. Other gases don’t absorb this energy, so they have no impact on the measurement result. OXYTRANS M ist ein tragbarer optischer Sauerstoffsensor zur Messung von O2 in z. B. entgastem Wasser, Würze, Bier, Getränken, flüssigen Lebensmitteln, CO2 und Schutzgasen. Das Instrument ist für Anwendungen ausgelegt, die maximale Empfindlichkeit und höchste Genauigkeit erfordern. Die Messtechnologie basiert auf der strahlungslosen Weitergabe von Anregungsenergie durch molekulare Wechselwirkung. Im Messkopf ist ein kleines Glasbauteil mit einer dünnen Schicht von Indikatormolekülen eingesetzt, das optische Fenster. Die Indikatormoleküle werden mit blau-grünem Licht bestrahlt, erzeugt durch eine LED im Sensor. Sie absorbieren das einfallende Licht und werden in einen höheren Energiezustand befördert. Eine gewisse Zeit später konvertieren die Moleküle zurück in ihren Grundzustand, wobei rotes Licht ausgestrahlt wird. Das Rotlicht wird im Sensor detektiert. Falls O2 Moleküle vorhanden sind, wird die Energie von den angeregten Indikatormolekülen auf den Sauerstoff übertragen. Das detektierte Signal verringert sich mit steigender Konzentration an O2 Molekülen im Produkt. Andere Gase absorbieren diese Energie nicht, somit haben sie keinen Einfluss auf
