Advanced fluid models for resonant online oil condition monitoring systems

Non-Dispersive Infrared Sensor for Online Condition Monitoring of Gearbox Oil

The condition of lubricating oil used in automotive and industrial gearboxes must be controlled in order to guarantee optimum performance and prevent damage to machinery parts. In normal practice, this is done by regular oil change intervals and routine laboratory analysis, both of which involve considerable operating costs. In this paper, we present a compact and robust optical sensor that can...

New Electric Online Oil Condition Monitoring Sensor – an Innovation in Early Failure Detection of Industrial Gears

A new online diagnostics system for the continuous condition monitoring of lubricating oils in industrial gearboxes is presented. Characteristic features of emerging component damage, such as wear, contamination or chemical aging, are identified in an early stage. The OilQSens ® sensor effectively controls the proper operation conditions of bearings and cogwheels in gears. Also, the condition o...

Condition Monitoring for Twin-Fluid Nozzles with Internal Mixing

Abstract—Liquid sprays of water are frequently used in air pollution control for gas cooling purposes and for gas cleaning. Twin-fluid nozzles with internal mixing are often used for these purposes because of the small size of the drops produced. In these nozzles the liquid is dispersed by compressed air or another pressurized gas. In high efficiency scrubbers for particle separation, several n...

Online Nonintrusive Condition Monitoring and Fault Detection for Wind Turbines

Online, Continuous Monitoring of Mechanical Condition and Performance for Criti

This paper outlines the typical problems seen in reciprocating compressors and shows that the existing type of monitoring systems, consisting of vibration level, rod drop, rod runout, and valve cap temperatures, often misses many of them. The advanced compressor monitoring system, which uses dynamic compressor cylinder pressure, directly targets these areas. This system not only provides the in...
