4.3 - A Multichannel IR Sensor System for Condition Moni¬toring of Technical Fluids

T. Bley & A. Schütze
Determination of the current fluid condition is of interest in many applications making use of technical fluids. In order to avoid machine downtime due to excessive deterioration, oil changes are often made well before reaching a critical state based on a fixed number of operating hours or, alternatively, analyzing oil samples in the lab. However, oil sample analysis is rather costly and some uncertainty concerning the machine condition remains during and between sampling. This problem...
