BEARING FAULT DETECTORS ■ Detects impacting associated with bearing faults, including spalling, cracking and lubrication problems Outputs a 4-20 mA current output signal for peak acceleration Bearing faults create metal-to-metal impacts that manifest in vibration data as high-frequency, high-amplitude peaks. Typical vibration transmitters that utilize the RMS process cannot accurately identify these peaks. As an alternative, IMI Sensors has developed two products with a 4-20 mA output that are specifically designed to identify high-frequency, high-amplitude peaks. Operates with PLC, DCS, SCADA, alarm and control systems TYPICAL APPLICATIONS Normal operation Bearings in: Onset of fault ■ Green Line: True Peak Peak Value Green Line: Captured Value Orange Line: Overall RMS Value Orange Line: Overall Value Blue Line: Analog Vibration Blue Line: Analog Vibration IECEx IECEx

BEARING FAULT DETECTOR FUNCTIONALITY AND FEATURES Bearing Fault Detector (Model 682C05): The Bearing Fault Detector offers three simultaneous signals- raw analog voltage output, current output proportional to overall vibration and current output proportional to true peak acceleration. The signal processing begins with a 100 mV/g VAC signal from a remotely-mounting ICP® accelerometer. Output Signal Processing Spectral (FFT) analysis for fault diagnostics VAC signal is re-transmitted through the BFD’s BNC jack unprocessed Ideal indicator of faults that occur 4-20 mA Current at machine running speeds,...
