Two Minute Tips
Nonmelting Grease for High-Temperature Bearing Applications
Bearings operating in or near heat-generating equipment are subject to temperatures that cause ordinary greases to melt and run, leaving critical bearing surfaces unprotected. A reliable long-lasting grease that can withstand extreme heat is needed to extend re-greasing intervals and prevent premature bearing failures.

Online Monitoring Systems | How to choose?
Online monitoring is the process of utilizing permanently mounted sensors to regularly check the condition of a machine. Online monitoring should consist of more than just vibration sensors. Given there are many different failure modes it is best to utilize a variety of sensor types to monitor the necessary variable to ensure early warning of failure.

Warning Signs of Pump Cavitation
Pumps are critical pieces of equipment in a large variety of industrial settings. Although they are routinely monitored as part of a facility’s CBM program, the data captured in this way isn’t always enough to identify the signs of early-stage pump cavitation. Vibration data can provide valuable insight into the pump’s condition, and with the right monitoring setup can help you identify developing cavitation before serious damage or failure occurs.

The Importance of Balancing a Turbo
Internal combustion engines use turbochargers as a way to output more power. Some turbocharger impellers can reach speeds up to 300,000 rpm.
Unbalance at high speed generates vibration that will not only reduce the engine performance, but may eventually cause permanent damage to the whole system. Needless to say, turbo balancing machines are important in maintenance activities for turbocharger systems to work in optimal conditions.

Automatic RPM Identification From Vibration Data
Vibration analysis requires a correct identification of the rotational speed of the machine. How the different frequencies of the spectrum are related to RPM, identifying with high accuracy the order of each frequency, is essential for the analysis process.

Accelerometer Hermeticity
At its core, hermeticity refers to a seal or closure being complete and airtight. There are different levels of hermeticity, though, depending on the quality of the seal, and the only way to measure is through a leak test, usually performed with helium.

Condemning a Motor Using MCA™
Experience has shown that 20 to 40 percent of motor systems tested may have some sort of alarm condition. Just because a motor has exceeded the alarm limits in MCA Basic™ or MCA PRO™, it does not necessarily mean the motor will fail or should be stopped immediately. For over 30 years, the dedicated staff at ALL-TEST Pro have gathered data and resources to determine when a motor will most likely fail on the most common 3-phase squirrel cage motors.
