Detector III can be used to monitor machine vibrations according to ISO 10816 and the condition of rolling bearings by means of the demodulation detection method. The raw and demodulated signals stored in the system can be used later for analysis of signals in relation to time and frequency ranges.

6 1. Principle Operation balancing using Detector III The FAG Detector III is a tool that can be used to not only identify but There are many different reasons for unplanned stoppage of machinery. However, a not inconsiderable percentage can be attributed, directly or indirectly, to imbalance or misalignment. Others Bearing damage Imbalance and misalignment During measurement, the speed should be constant (at least 40 or 600 rpm for ISO 10816). The device records the sensor During operation, imbalance can signals according to the selected generate considerable vibrations bandwidths and calculates the that lead to secondary damage characteristic values.

FAG Detector III compares the newly This results in machine failure measured characteristic values with and thus unplanned production the defined limit values for the shutdowns. main alarm for this measurement location. If this threshold value is exceeded, this is displayed immediately on the device. With the aid of trend analysis, the user can estimate when an alarm will probably occur. When an alarm is triggered, an alarm report can be automatically generated and printed out.

8 In order to allow comparison of values, they must be recorded under the same conditions. After reference measurement, measurements should be carried out at regular intervals. 2. Principle Operation also easily and efficiently eliminate Trendline bearing database Configurable report such conditions. During balancing work, the simple The integrated bearing database A very useful feature of the user guide gives effective support. (containing approx. 20 000 bearings software, especially for companies Step by step, the device's software from various manufacturers) allows using the FAG Detector III in service guides the user through the balanc- considerably simplified and work, is the expanded report ing procedure.

The bearing database can be expanded individually by each user to include further entries. The results of the balancing work are transferred to the software FAG Trendline.
