Figure 3. Creating a route using a structured database That information is generally not available in the practice of their business. Today’s portable instruments used for route-based oil analysis are able to outperform lab instruments because the information available at the point of the test identifies the appropriate test methods, analysis parameters and alarm limits for each lubricant sample on a sequential route. Simply stated, route-based oil analysis allows technicians to do a better job of oil analysis and get it done quickly because their instruments are programmed to always select the correct protocol and reference information for each point along the route. Six elements must normally be addressed for a technician to conduct a route-based analysis with a portable analyzer in an industrial plant or around a fleet of mobile equipment: 1. Create a structured database. 2. Populate the database with route information associated with the oil and equipment in the database. 3. Select a preferred inspection route. 4. Transfer route information into a handheld analyzer. 5. Apply route information in the analyzer during in-field analysis. 6. Upload measurements and findings to the database. Database Creation A maintenance server is configured to generate oil analysis routes based on a set of analysis rules (see Figure 3). These rules may be based on time, a previously existing condition or specified by the maintenance engineer. The route could include the sequence, asset identification and/or reference oil information, such as oil name, type, property limits, etc. Populating the Database The generated route is synched between the maintenance server and the device to be used for the route-based analysis. This can be accomplished in a number of ways, including a straight database synch, a file download/transfer or a barcode list, which could serve the dual purpose of a sample bottle label. For a set of recurring routes, a binder could be constructed of 8½-by-11-inch sheets of paper that could be pulled out and scanned whenever a given route is indicated (see Figure 4). Sample labels afford the benefit of 4| January-February 2014 | www.machinerylubricationindia.com potentially including other data independently collected from the lab or other onsite test instruments into this same sample record. Still another way to accomplish this would be for the user to print and laminate labels and attach them to each sample point. Then, when the technician walks the route, he or she could scan the barcode to add that location to the route in the database. Route Analysis With the route information downloaded into the handheld machine, lubricants are analyzed at each asset in sequence. The handheld unit operates in a selfguiding fashion so that the user is presented with the next asset’s information when finished with the analysis of each asset. This may include GPS coordinates of the asset, a picture, serial number or simple instructions on where to find the next asset. The handheld device contains all the calculation tools necessary to perform the analysis. The results of each lubricant scan are stored in the handheld unit. The technician can see the results as soon as they are produced. This can include
