A. Agoston OVE, C. Schneidhofer, N. Dö rr, B. Jakoby OVE Fourier transform infrared (FTIR) spectrometry is an indispensable laboratory measurement method for the evaluation of the condition of lubricating oils. This technique allows the determination of several oil properties, e.g., degree of oxidation, nitration, and soot content. One of the most important parameters is the oxidation number, which is a measure for the oxidative degradation of the oil, in particular of the base oil. The utilisation of a sensor assembly consisting of an IR source, IR detector, oil measurement cell, and narrowband IR filters enables the detection of significant oil parameters at selected characteristic bands within the IR spectrum.The applicability of the sensor concept described above is illustrated by evaluating the oxidation number from the absorption of a significant IR band and a reference band. Our investigations showed that the implementation of an IR sensor for on-site or even online oil condition monitoring is possible. An appropriate choice of IR filters and the development of a sensor signal algorithm enable the determination of further oil properties, which can be derived from the infrared absorption spectrum. Ein Konzept eines Infrarotsensorsystems zur Ö lzustandsanalyse.Die Fourier-Transformations-Infrarotspektrometrie (FTIR) ist eine unerlä ssliche Labormessmethode zur Beurteilung des Schmierö lzustandes, mit deren Hilfe eine Vielzahl wichtiger Ö lparameter wie Oxidation, Nitration, Rußgehalt und dergleichen bestimmt werden. Eine wesentliche Kenngrö ße ist die Oxidationszahl, welche ein Maß fü r die thermisch-oxidative Alterung des Ö les, insbesondere des Basisö ls in Schmierstoffen, ist. Die Verwendung eines Aufbaus bestehend aus IR-Quelle, IR-Detektor, Probeaufnahme und optischen Interferenzfiltern ermö glicht die Bestimmung ö lrelevanter Eigenschaften aus charakteristischen Banden im Infrarotabsorptionsspektrum.Am Beispiel der Oxidationszahl kann gezeigt werden, dass eine derartige Sensorvorrichtung zur Bewertung signifikanter Banden in Infrarotspektren fü r die Online-Ö lzustandsanalyse herangezogen werden kann. Die geeignete Wahl der IR-Filter und die Entwicklung eines Auswertealgorithmus erlaubt die Ermittlung weiterer Ö lparameter, die mittels Infrarotspektrometrie zugä nglich sind.Schlü sselwö rter: IR-Sensor; Ö lzustandsü berwachung; Infrarotspektrometrie

“…It is recommended, by a number of engine and lubricant manufacturers, that the oil should be changed when the AN equals the BN values 17,18,19 . Attempts in miniaturising infrared (IR) 20 sensor for oil chemical monitoring have been reported, however, little success is achieved so far. Smiechowskia et al developed an Iridium oxide sensor for non-aqueous solutions such as industrial lubricants 21 .…”

Lubricating oil of moving parts is a critical factor for the performance and longevity of cars and industrial engines. The lubricant degradation occurring during application can be detrimental to the proper operation of lubricated machines if the oil is not changed in a timely manner. However, the oil degradation process is often influenced by a number of parameters, such as the operating temperature and contamination. This offers a challenge to oil monitoring technologies. This study investigates the feasibility of detecting changes in oil acidity using Ion Selective Electrodes (ISE) fabricated using thick-film (TF) screen printing technology. The working electrode is a TF Ruthenium Oxide (RuO 2 ) ISE; the reference electrodes are three different types of TF reference electrodes and commercial glass pH reference electrode. Artificially degraded oil samples from oxidation tests and model oils produced by adding acid have been used for the evaluation of the sensors. Acid Number (AN) of all oil samples was obtained using conventional titration method. The results show that the TF electrodes responded linearly to the change in oil acidity under different temperatures. Their sensitivity in detecting oil acidity in the model oils is found to be much higher than that of the commercial electrode. Initial analysis also shows that the sensor responses decrease as the temperature increases.

This paper presents a review on condition assessment of some of the most critical components in the power grid today, such as transformers, rotating machines and cables and their accessories. The main purpose is to identify methods that can be applicable for high voltage equipment for subsea use. The question addressed is what diagnostic tools should be used to detect apparatuses with a high probability of failure during service.It is shown that today, only distributed temperature sensing systems are used for subsea applications. At the same time, the majority of condition assessment techniques used onshore can be adjusted for subsea use, particularly methods applicable for on-line monitoring.
