IMI Sensors: A PCB Piezotronics Division Bearing Fault Detector PLUS USB Programmable loop powered device with 4-20mA output contained in a typical vibration sensor housing ideal for fault detection in rolling element bearings Highlights n Combination 4-20 mA sensor PLUS vibration transmitter USB Programmable: Fine tune transmitter to your specific machine parameters Various output options: Integrates with your PLC system Output specifically tuned for sensing early faults/failures in rolling element bearings Motors Fans Pumps Critical rotating machinery Fixed speed rotating equipment Variable frequency driven machinery The 649A03 Bearing Fault Detector PLUS is a USB Programmable loop powered device with 4-20mA output, all contained in typical vibration sensor housing. It is specifically designed to provide early warning of typical ball/rolling element bearing faults such as cracked races, spalling, brinelling, and looseness. The model is similar to IMI’s 682B05 DIN rail mounted Bearing Fault Detector; however, it is not a direct substitute. Like the 682B05, it provides a 4-20 mA output specially tuned to detect high frequency bearing faults. Unlike the 682B05, which is mounted in a box connected to an external sensor, the 649A03 has a sensor form factor that can directly mount to the machinery. It differs in that it provides several additional outputs, but can only provide one at any given time. These specialized outputs can be selected using the USB Programming function of the transmitter. The primary use for the Bearing Fault Detector PLUS is in applications with critical rotating machinery that needs continuous monitoring. The 649A03 is specifically designed to be sensitive to high frequency faults in rolling element bearings, which indicate the early stages of damage. It serves to provide a proactive warning to any Predictive Maintenance technician by increasing its 4-20 mA output proportional to this high frequency vibration. They can use this 4-20 mA scaled output to both trend the data and create vibration alarms with a PLC or DCS to closely monitor when machinery should be shut down and its rolling element bearing should be replaced. Bearing Fault Detector PLUS Model 649A03 The Bearing Fault Detector PLUS has five different outputs which aid in fault detection, and these are user-selectable by a simple software program through a PC’s USB port. The output options include RMS acceleration, True Peak acceleration, Compensated Peak acceleration, Crest Factor, and Crest factor Plus. Many of the various output options require the speed of rotation as an input for programming. Due to this feature and the nature of bearing vibration frequencies, the 649A03 is best suited for fixed speed rotating equipment; however, the Crest Factor Plus uses an algorithm which normalizes the output across various running speeds and is designed for use with variable frequency driven machinery.
