Idler Monitor Setup Menu

* Units - English or Metric. Determines the system's units of measurement. For example, select Metric to set belt speed in m/s and idler diameter in mm. Select English to set belt speed in ft/min and idler diameter in inches.

* Sensitivity - Enter the microphone's sensitivity in mV/Pascal of sound pressure. The default sensitivity is set to 40 mV/Pascal for the microphone provided by SKF. This should not need to be changed unless a different microphone is used.

* Plant Name - Enter the mine, company or plant name. This information (along with the following three fields) is stored to memory and saved with the recorded conveyor sound data for identification purposes.

* Location - Enter the conveyor or machine's location.

* Description - If necessary, enter additional description for identification purposes.

* Asset Reference - Enter the conveyor asset number, serial number or tag number.

* Belt Speed - Enter the conveyor's belt speed. Belt speed and idler roller diameter are used to calculate roller rotation speed and bearing fault frequencies.

* Idler Diameter - Enter the conveyor's idler roller diameter. Idler roller diameter and belt speed are used to calculate roller rotation speed and bearing fault frequencies.


The next four fields allow you to alter alarm thresholds for the Idler Sound Monitor's four acoustic measurements. The default alarm threshold settings are set to best detect idler faults for typical conveyor conditions and should only be altered if they prove insufficient for your conveyor conditions. 

* True Pk Threshold - Specify alarm threshold for the Acoustic Enveloping (PaE) true peak overall measurement.

* RSS Threshold - Specify alarm threshold for the Acoustic Enveloping (PaE) Root Sum Square (RSS) Overall measurement.

* Kurtosis Threshold - Specify alarm threshold for the Kurtosis measurement. 

* HAI Threshold - Specify alarm threshold for the Harmonic Activity Indicator measurement.

* Save To - (Internal or Card) specify the medium to record to, either the Microlog's internal hard drive or an inserted SD card.
