Condition Monitoring is a Bit Like Going to the Doctor
Condition monitoring is a bit like going to the doctor. Doctors may look at your electrocardiogram, blood sample results, blood pressure and temperature. These tests are just a few of many examination techniques available to them, some more complex than others. So why are they done?

Machine Health Basics For The OEM Design Engineer
Analyzing machine vibration as a means of monitoring healthy operation and diagnosis of emerging problems is a relatively mature specialization, long practiced on turbines and motor-pump trains. Condition Monitoring for the factory today is generally implemented by a skilled practitioner equipped with a handheld data-logger, collecting and processing signals from a tethered vibration sensor during a periodically scheduled, route-based maintenance program.

Can Lubrication Programs Be Green?
The traditional environmental lubricant has been one that is either biodegradable or is formulated from biobased materials. From a more holistic standpoint, lubrication programs have been environmentally sustainable in other ways for years.

Monitoring the Machine Condition Lifecycle
This 5 minute fact discusses the machine condition lifecycle curve, three distinct operating windows within that curve and methods to extend the usable life of equipment. You’ll hear about methods to monitor equipment during a proactive maintenance phase, predictive maintenance phase and finally the fault phase. Finally, solutions to help implement monitoring during all phases of the machine lifecycle will be discussed.

Measuring Varnish Potential in Lube Oil
Lubricating oil in gas turbines and hydraulic systems is unfortunately subject to the ravages of varnish. It is well-documented that varnish is an insoluble contaminant comprised of oil degradation by-products and sometimes depleted additive molecules..
