Condition monitoring through oil analysis tests

Condition Monitoring of Oil using Wireless Sensor Network

Leakage of oil from different oil sections of dumper (cat773) can lead to fire accident and also machine failure if any considerable change in chemical or physical properties of oil takes place which results in loss of property and also life. The system model proposed by us is divided into transmitter and receiver section. The entire control system is based on microcontroller and ZIGBEE techniq...

Oil Condition Monitoring Using a Thermal Conductivity Sensor

In recent years, the monitoring of oil-based liquids has gained increasing importance in various branches of the industry. In this contribution we discuss the application of a miniaturized thermal conductivity sensor for the monitoring of water contamination and deterioration processes in mineral oil. The sensor, which utilizes the hot film principle, features a molybdenum resistive structure s...

Title : Condition Monitoring Using Automatic Spectral Analysis

Within the frame of machinery maintenance, spectral analysis is a helpful tool. Therefore, an automatic spectral analysis tool, capable to identify each component of a measured signal would be of interest. This paper studies a new spectral analysis strategy for detecting, characterizing and classifying all spectral components of an unknown process. Indeed, any vibration signal can be considered...

Machine-Condition Monitoring using Vibration Analysis

Availability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval

Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
