The need for eliminating catastrophic damage of structures and breakdowns and unnecessary maintenance costs in production processes has and will continue to drive the adoption of condition monitoring solutions across several industries.
Vibration amplitude may be measured as a displacement, a velocity, or acceleration. Vibration amplitude measurements may either be relative, or absolute.
By Condition monitoring we mean continuous evaluation of the health of plant, equipment and structure throughout its serviceable life.
Condition and Vibration monitoring can, in many cases, be extended to provide primary protection, but its real function must always be to attempt to recognise the development of faults at an early stage.
The proposed new Photonics technologies are highly sensitive, and additionally, are free of the many limitations encountered by the existing conventional technologies.
VIDUR and VEDA are Photonic Systems for Real Time Vibration and Condition Monitoring systems.
Worlds one of its kind non contacting probe technology in monitoring any type of Vibration.
VIDUR and VEDA are low powered, compact, portable and can easily be deployed at any location for real time vibration and condition monitoring in a non-intrusive fashion, even at inaccessible locations.
Accurately measures maximum displacement from the mean position Amplitude, Velocity and Acceleration in time and frequency domain.
Condition monitoring is critical to forestalling breakdown, as it works on the philosophy of predictive (prognosis-driven) maintenance.
Most cost effective with highest accuracy levels even in harsh environment.
Easy to fit where space is constraint. And has long useful life.
Consumes less electrical energy and can run on batteries.
Can monitor from far away distance, wherein approaching to typical part of machine is difficult.
Moreover, using continuous wave lasers and appropriate photonic technologies ensure extremely high sampling rates thus solving the spectral frequency constraints generally faced by the existing NDT technologies.
The removal of unwanted modal parameters obtained from noise or external factors can also be effectively implemented.
The dynamic response of the structure and rotating machines can be studied with superior sensitivity using photonics, wherein the obtained data can be further interpolated to obtain the modal parameters - which is used for damage detection or SHM.
The uniqueness of these systems is that in addition to monitoring real time vibrations with high sensitivity (nanometre resolution), one can also listen to the sound at the observation location, remotely.
Vibrational displacement, velocity and acceleration parameters can be simultaneously extracted in real time in both time as well as frequency domains from remote locations, non-intrusively.
Data can be provided on mobile / Cellular application . Patterns / Trends and historical data can be mapped.
Optimizing maintenance activities during planned shutdowns and lowering the instances of unscheduled outages.
On Board Portable Health Monitoring System can be installed on Submarines / Aircrafts for Turbines and other machines that will alert technicians ashore or ground to sub-par performance of equipment and systems, signaling potential breakdown.
Constant health monitoring will maximize asset availability besides extending its service life.
Of all the predictive maintenance (PdM) technologies, vibration analysis remains the best measure of machine health.
This is true because vibration monitoring can alert us to so many different conditions that may indicate potential machine failures.
