Bearing Fault Detector n Bearing condition transmitter n Provides early warning of bearing and gear faults n Detects impacting associated with spalling cracking and lubrication problems Model 682B05 Bearing Fault Detector BFD is an advanced vibration signal conditioner designed to provide the earliest warning of imminent machinery failure The unit works with a 100 mV g ICP accelerometer and serves to deliver two 4 20 mA output signals that are proportional to the measured vibration levels of operating rotating machinery In order to enable detection of a wide variety of machinery faults the 4 20 mA signals are conditioned to characterize two unique vibration measurements one containing high frequency peak data and the other containing low frequency rms data These 4 20 mA signals may be monitored alongside other plant process variables using familiar PLC DCS SCADA alarm and control systems An additional analog voltage output signal is provided for spectral analysis of the monitored vibration for fault diagnostic purposes The unit employs a patented signal conditioning technique US Patent 6 889 553 that provides the unique ability to detect bearing and gear problems at their earliest stages thus permitting ample maintenance planning to avert a catastrophic failure The simplified 4 20 mA signal monitoring approach represents a cost effective alternative to complex vibration monitoring instrumentation and associated training Bearing Fault Detector Model 682B05 n Provides early warning of bearing and gear faults n Operates with PLC DCS SCADA alarm and control systems n Outputs 2 discreet 4 20 mA signals one proportional to peak acceleration the other proportional to overall vibration Product shown at actual size IECEx IECEx IECEx IECEx POWER LED ANALOG OUTPUT 3 9 99 0 9 22 5 4 5 114 5 0 5 12 7 POWER LED ANALOG OUTPUT 3 9 99 0 9 22 5 4 5 114 5 0 5 12 7 Power LED Analog Output 0 9 in 22 5 mm 3 9 in 99 mm 0 5 in 12 7 mm 4 5 in 114 5 mm 120 visit us online at www imi sensors com 1 716 684 0003
