New oil is typically never clean enough for common applications and should be filtered before installation. A good rule of thumb is that new oil should be filtered to two (2) ISO levels cleaner
In the midst of this economic downturn, are you being asked by your company to identify ways to save money? Now is the time to find the bad actors in your motor population that are costing your ...
Did your facility recently have an “incident energy analysis” / “arc flash survey” / “70E sticker program” completed? After every piece of switchgear, MCC and panel board has been evaluated, many
You’re 17 times more likely to introduce defects during equipment startup than during normal equipment operation. Additionally, over 90% of rotating equipment has defects at startup that
So, ...

IRISS, a leader in the industrial infrared (IR) window market for energized electrical inspections and safety, has released the second edition of 10 Things You Need to Know About Infrared Windows. A primary focus of this book is to educate businesses and their electrical personnel so they can perform safer, more efficient electrical inspections resulting in increased reliability.
Many people believe that all they need is a good flexible coupling. They believe that flexible couplings will eliminate the need for performing proper machinery alignment. Nothing could be
The analysis of vibration monitoring data to monitor the characteristic changes in rotating machinery caused by imbalance, misalignment, bent shaft, mechanical looseness, faults in gear drives,
The CBS ArcSafe® RSA-12A, a custom-built remote switch actuator designed to operate all DS types of electrical circuit breakers while keeping technicians well outside the arc-flash danger zone, has won the Occupational Health & Safety New Product of the Year Award in the Electrical Safety category.
Contamination control is a critical part of equipment reliability. It is likely that equipment problems will occur if both water and particles are not removed from the system's oil. Removal of
Vibration monitoring and analysis are recognized as key components of a well-founded reliability centered maintenance (RCM) program. Machinery health and long-term reliability are interpolated from trends in vibration amplitude; however, often these levels increase to dangerously high values with little or no warning! Resonance is frequently identified as the root cause. Understanding the physics of natural frequency, and the tools and methods used to recognize and confirm a resonant condition are essential skills for the vibration analyst.
Collecting ultrasound data should not be a robotic task. Walking through the plant with a heightened sense of hearing, there are a lot of observations made. Creating field notes can provide an
NFPA 70E, CSA Z462 and OSHA 1910 are very clear: equipment must be de-energized ("electrically safe work condition") if the worker is exposed to a possible hazard (within the limited approach
Fan blades and centrifugal pump vane frequencies can be monitored in a demodulated current spectrum at a frequency that is equal to the number of blades (or vanes) times the pole pass frequency
The CBS ArcSafe® RSA-12A is a custom-built remote switch actuator that remotely operates all styles of Westinghouse/Cutler-Hammer DS/DSL power circuit breakers. The RSA-12A is designed to operate on equipment with either manual or electric charging mechanisms and is compatible with all manufacturers and sizes of DS breakers without any modification to the breaker.
General Mills started ultrasound measurements on a series of five cookers. The electric motor bearings are used to drive either side of a nip roll. They noticed that one set of bearings had
1) Motor insulation degrades naturally over time, but many factors can accelerate degradation leading to shorts and motor failure. 2) Surge tests play an important role in assessing the strength of insulation, and allow maintenance personnel to avoid costly unexpected motor failures and downtime. 3) Surge tests with SKF static motor analyzers can be performed over and over again on a motor with no tangible degradation to insulation strength or motor health and performance.
Process Sensors Corporation has released its new Infrared Temperature Overview Brochure. Titled “Non-Contact Infrared Temperature Measurement for Industrial Process and Research Applications”, the twelve-page, full color brochure provides a brief overview of the many types of infrared sensing devices PSC has to offer, as well as explaining its corporate mission, touching on many industrial applications and reviewing principles of infrared theory and practices.
