Visual and Vibration Monitoring

Visual Monitoring

It is the monitoring technique, which involves inspection and recording of surface appearance. Normally, the monitoring is done by naked eyes, but may require the use of telescopes, microscopes and various other optical equipment if necessary. Sometimes it may even involve the use of boroscopes to see inaccessible places, or the use of photography or surface imprinting for record purpose.

Vibration Monitoring

The noise and vibration are the most important parameters to monitor a machine, particularly in the moving parts such as shafts, rotors, cutting tools, gears, etc. The vibration level is recorded by attachment of a transducer like velocity probe, accelerometer or proximity probe to the machine. Special equipment is also available for using the output from the sensor to indicate the nature of the vibration problem and even its precise cause. In some cases it may become necessary to use the principles of Sonics and acoustics.
