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..

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..

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.
