Condition monitoring (MCM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault.Vibration, noise, and temperature measurements are often used as key indicators of the state of the machine. Trends in the data provide health information about the machine,help detect machine faults early and allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences.
Precise acceleration measurement on the housings of the bearings, motors and gearboxes offer a decisive insight into the operation of the rotating parts. It allows the maintenance team to detect wear, leakage, bearing failure or change in stiffness.
IEPE accelerometers coupled with the MonoDAQ-E-ACC data acquisition modules provide 20 kHz measurement bandwidth (40 kS/s sample rate) per measurement point. The systems can be distributed all over the production hall with only a single network cable connecting them module-to-module, making the cabling extremely simple and inexpensive.The software for data acquisition and analysis auto-recognizes the modules and sensors, which requires no special learning to start recording the data. This way the engineer can focus on studying the data using FFT, order tracking, correlation and other methods of dynamic signal analysis.
