Two Minute Tips
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.

Phase Simulator
The simulator of measuring system (Lead Phase or Lag Phase), phase convention (Rotating Scale or Fixed Scale) and scale direction (Contrary to Rotation or Same of Rotation), shows, during rotation, for the first turn the tachometer event...

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..

Leading and Lagging Indicators
Leading indicators are those that occur early in the P-F curve while lagging indicators occur later in the failure cycle. Both are key indicators, but it is important to know which one you are dealing with to better diagnose the severity of the situation..

Multiple Technology Approach to Motor Diagnosis & Troubleshooting
The multi-technology approach to motor diagnostics means using different testing technologies to complement and validate each other. For example, when a vibration technician suspects a possible rotor problem in a critical application, and the cost to repair or replace requires a loss of production, where the motor’s cost is small compared to the incurred costs of the shutdown.

The Evolution of Condition Monitoring
Condition monitoring is often thought to be a waste of time, due to the shear cost of equipment and training required to ensure that maintenance staff are competent in using the equipment correctly and are able to interpret the vibration spectrum.

Motor Storage
Proper motor storage is critical if we hope to achieve normal life expectancy from our electric motors. Not only is proper motor storage important for good motor health, it may be required to maintain a warranty on motors that we purchase..
