Condition monitoring
Chain monitoring avoids production downtime
The CCM-S monitoring system developed by Iwis continuously measures the wear elongation of chains during operation and provides an early warning before a chain needs to be replaced.
If chains stretch and wear due to temperature and load, or if chains running in parallel are unevenly elongated, a deviation of just one percent from the nominal chain pitch can cause problems in a system. Systems and machine elements must therefore be monitored and checked regularly.
However, it is often too late when systems give an indication that maintenance or readjustment is required. Predictive maintenance allows machine manufacturers to react more flexibly and act economically.
Continuous monitoring during operation
With the CCM-S (Chain Condition Monitoring - Smart) chain elongation monitoring system from Iwis, the elongation of chain drives can be permanently monitored using sensors during operation. The system measures the elongation of chains and provides timely information on what measures need to be taken and when, and whether a chain needs to be retensioned or replaced. Thanks to the system's intelligent data analyses, service personnel can plan inspections and deployment requirements at an early stage. Maintenance work is also reduced as the CCM-S tells the technician which drive chain needs to be replaced before the system is opened. The chain elongation is measured without contact.
Easy to retrofit
The module can be easily retrofitted in various chain applications. The CCM-S module works according to the plug & play principle, and no presettings or calibration measures need to be carried out in the application. If the module is installed in existing chain drives, users can immediately start evaluating the data on wear in the chain drive either via iwis software or via IO-Link.
The system can also take measurements regardless of the speed. It always records two measured values at two different sensor points, with both measured values being recorded at the same time. The measurement is inductive.
With the support of the SLE function (Segment Link Elongation), the entire chain is broken down into individual segments. These are measured individually and evaluated for deviations from the average chain elongation. To do this, magnets must be attached to both sides of the outer plates of the chain strand in order to define a start and end point. The system then generates a bar chart showing the elongation of individual chain segments. The CCM-S system can also measure the individual elongation of individual chain segments and displays the results clearly.
