Since the launch of the FAG "Smart Check" Beginning 2011 achieved the compact meter of Schaeffler great successes. Users of different industries are satisfied that there is an uncomplicated and economical solution, with the smaller or less mission critical machines can be monitored. The paper describes some applications:

Diagnostic success on vibrating

Since vibrating screens often at the beginning of a longer process of production are, introduces disruptive downtime and an associated loss of production at significant costs. To increase the availability of their own vibrating screens, and thus the machine availability of their customers sought the Spaleck GmbH & Co. KG for a reliable on-line monitoring. The meter has been proven in the harsh conditions prevailing in the area of ​​vibrating screens, and convinced all along the line. The smart metering system recognizes the important Schwingungssiebzustände and ensures that the system availability. Since vibrating screens themselves cause high vibration level, the challenge is to the right information to filter out damage diagnosis. This rule only very few and usually much more expensive systems. The SmartCheck can also easy to set up and operate. This example, allow more than 20 parameter templates, on the meter of the house and has also ensured Spaleck trouble-free use.

Measurements of the electric motor

In electric motors, bearing defects at an early stage can determine the basis of increased vibration and noise. Schorch the Electrical Machines and Drives GmbH was looking for a safe yet low-cost method to monitor their units both in bearing damage as record other parameters such as temperature, load and speed. The comprehensive database should be used to permanently about the overall condition - even from hard to reach or remote machines - to be informed. Furthermore, a history of access to data must be possible to get more information about the long term behavior of the machines in the field. To this end, the installed Schorch SmartCheck on the drive motor of a piston compressor. For intelligent process control other parameters such as the ambient temperature and the engine housing temperature were recorded and correlated with the oscillation signals. Priority for the customer, however, was the result of the vibration measurement, which he was informed early on an incipient bearing damage.

Monitoring of decanters, pumps and compressors

Well as in other applications scored the SmartCheck and triggered the monitoring tasks placed on it. He presented, for example, clearly identified on a decanter if the current unbalance of the screw or of the drum is caused. A secure association is immensely important for the maintenance because depending on the source of the imbalance, completely different maintenance is necessary. The assignment of these so-called "floating balance" between screw and barrel, other surveillance systems often do not make errors.

For measurements on the vacuum recognized SmartCheck unbalance, misalignment and bearing wear. These critical conditions, depending on the application result in stoppage of a complete line of vacuum and cause costly failures.

For units that are located in remote locations, such as pumps for flood control or reservoirs, the SmartCheck scores with its great flexibility. Means of remote monitoring, the recorded data can conveniently be read remotely. Without having to be on site, the operators are constantly informed about the state of their equipment and can take immediate countermeasures in case of alarm.

Further diagnostic successes he achieved with the use of compressors. These are operated partially exposed to severe stresses and significant vibrations, which can result in a very short time an unplanned shutdown. With the Smart Check this risk could be reduced and a comprehensive monitoring can be ensured. Thus, the unit recognized example bearing damage so early that touching the screw was prevented. Because of maintenance could be done much cheaper. As for installing the Smart Checks no mechanical conversion is required, it can also be easily retrofitted to existing compressors.
