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..

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..

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.
