Avoiding disastrous breakdowns of machinery is imperative to any business, so proper condition monitoring is vital. Twenty-four hour monitoring of an entire system and its housing to search for every kind of flaw that could occur whenever, is somewhat of a losing battle. Of course, with computers to watch the machines, it is a battle that can be fought and won. Machines can't yet think for themselves of course, so you do still need at least one technician whose job is to monitor the monitors. These devices are tools to help workers make more accurate diagnosis and stand in where it's impossible for human workers to read the signs. There are at minimum 3 categories of monitoring that companies can employ.
On-line monitoring is really great even in conjunction with other monitoring systems, as it is a passive monitoring method. These methods utilize small sensors that broadcast the information about the system being monitored to the network. Also, a good benefit to this method is that the sensors can directly measure the conditions of the part they are placed next to, from the perspective of the part. Transmitting the analysis and or warnings to the employee's monitoring station allows for real-time analysis. If something is wrong, the sensor can alert the worker with an instant warning message. These sensors are frequently used as the first line of defense and can lead to other more involved monitoring steps.
An older but similar idea is on-site monitoring, this involves having an analysis lab at the facility to do brief investigations into the status of the machinery. Usually, workers would have a schedule check up day that would analyze the parts to see if they had the expected condition. This option is thought to work best in remote areas such as, mines or facilities where sample testing can be completed on-site as well. On-site monitoring frequently leads to more involved off-site monitoring when samples require more clarification.
When you need an exacting fix or economy of scale over speed, it is usually best to use a dedicated off-site location to batch process machine parts for analysis. When such measures are needed it is not unusual for a laboratory full of scientists to receive the samples for thorough testing. Because of time constraints involved off-site monitoring tends to be the last stage in an investigation about problems found in machinery at a site.
Making certain to do proper condition monitoring of your machinery and getting proper maintenance will save you the far greater cost of not only replacing the machinery, but also repairing any damage it may have caused. Each of the three monitoring methodologies have their own benefits. An excellent method is to combine any two procedures, say on-line to see problems and off-site for in-depth troubleshooting.
