Two Minute Tips
Measuring Fuel Consumption Through Heat Mapping
We had a customer who wanted to identify areas of the mine that could benefit from road maintenance. We started by taking samples of the fuel consumption rate…

MCA™ Improves DC Motor Testing Capabilities
Tasks for DC motors such as commutator & brush inspections, lubrication, are very important for their long-term successful operation. However, these inspections fail to determine the condition of the electrical winding or insulation..

Key Features for a Vibration Analyst
For more complex analysis, analysts require more advanced tools to better diagnose issues. Playing the TWF as an audio file is a good way of listening to the vibration to potentially hear knocking, pinging or high frequency whistling, denoting a problem to further diagnose, as if you were actually beside the machine.

Drive Input Imbalances
Current imbalances are sometimes referred to as a burglar alarm; generally problematic and need further diagnosis. However, imbalance at the inverter input under lightly loaded conditions is a normal phenomenon of the electrical circuit..

Testing for Water Content
Water is one of the most destructive contaminants faced by industrial maintenance departments. Some systems may be more tolerant to water, while others can be more sensitive. Some manufacturers have set limits as low as 30 ppm. Best practice would tend to indicate that it is beneficial to keep water contamination at the lowest level possible..

How To Optimize Your Measuring Rounds With Handheld Instruments
One way to optimize your measuring rounds is to opt for remote measuring points in new installations or turn existing measuring points into remote ones. There are several reasons this is a solid strategy. Below I will explain what extended measuring points are and why they are the better option.

Maximum Cable Length for Vibration Sensors
A vibration sensor produces an AC voltage dependent on the vibration signal being measured. As such, it’s subject to all the limits of AC signals. Long cable runs are likely to introduce enough capacitance into the sensor circuit to cause distortion, which makes being able to calculate cable length limits very important..
