Bearing Fault Detector Monitor and Detect Bearing Faults to Avert Catastrophic Failure Highlights n Provides Early Warning of Bearing and Gear Faults Detects Impacting Associated with Spalling, Cracking, and Lubrication Problems Outputs 4 to 20 mA Signals for Peak Acceleration and Overall Vibration Operates with PLC, DCS, SCADA, Alarm, and Control Systems Offers Analog Output Signal for Spectral Analysis and Diagnostics Conducts Continuous Vibration Monitoring — 24/7 Accepts Input from ICP® Accelerometers Patented Technology Easy to Install 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 to 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 to 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 to 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 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 to 20 mA signal monitoring approach represents a cost effective alternative to complex vibration monitoring instrumentation and associated training.

Model 682B05 Introduction Machinery vibration monitoring has long been recognized as an effective practice for detecting mechanical problems that ultimately cause machinery failure and downtime. Unfortunately, many instrumentation systems that are intended to assist the maintenance engineer with vibration analysis are complex — and require considerable training and experience in order to interpret measurement data. Too often, companies may encounter the loss of an experienced maintenance engineer due to downsizing or attrition — leaving critical machinery to run without being monitored and expensive...

is a 4 to 20 mA signal proportional to overall, rms or peak vibration. Internal selection switches allow a choice of acceleration or velocity measurements, peak or rms values, and a variety of fixed measurement ranges. The signal generated by the accelerometer is initially processed through a 1 kHz low pass filter. Then when set for velocity, the BFD passes this filtered signal through an integration circuit. When set for acceleration, the filtered signal bypasses the integration circuit. At the next stage, the signal passes through a true RMS conversion circuit. Finally, a gain stage provides...
