IMI Sensors' Bearing Fault Detector Plus is made to be a replacement for traditional vibration transmitter units
IMI Sensors' Bearing Fault Detector Plus is a new sensor designed to monitor rolling element bearings and provide a sensitive 4-20 mA signal to plant monitoring and control systems for early alarming of faults. The new model 649A03 is built to contain an accelerometer and 4-20mA transmitter and is constructed with multiple specialized outputs. When used with a control system, these outputs are designed to provide an early warning of bearing defects such as cracked races, brinelling, looseness and spalling.
The Bearing Fault Detector Plus is made for applications with critical rotating machinery requiring continuous monitoring. IMI's model 649A03 is designed to be sensitive to high frequency vibrations in rolling element bearings. It is built to serve as a proactive warning to any Predictive Maintenance technician by increasing its 4-20 mA output proportional to this high frequency vibration. The scaled output are made to be used to both trend the data and trigger vibration alarms in a PLC or DCS to closely monitor when machinery should be shut down and its bearing should be replaced.
The 649A03 is made to be a replacement for traditional vibration transmitter units as it uses the same loop power and 4-20 mA output. IMI has kept the installation requirements identical and added 4 additional outputs so that the user can select the detection method that best suits their application.
Designed with five different outputs that aid in detecting faults, the 649A03 is built to be programmed and tuned to specific machinery through a computer program simply using a USB cable. Users are made to be able to choose from traditional outputs including RMS Acceleration and Crest Factor. They can also select from specialized outputs including True Peak Acceleration, Compensated Peak Acceleration, and Crest Factor Plus - designed specifically to be sensitive to high frequency energy caused by bearing faults.
