Great example about sensor location during vibration data collection, allways place the accelerometer near the bearing load zone in order to capture the best data.
💡 For those new to the channel, this post from last year by Stuart Walker highlights the importance of collecting quality vibration data by ensuring the correct sensor location and mounting is chosen: 💬 "One of the first elements you learn about with vibration analysis is how to collect quality data by correct sensor location and mounting. 🍀 I am seeing a worrying trend of wireless sensors been placed in the middle of sizeable motors and machines hoping to pickup bearing defects and lubrication issues at the DE and NDE many feet away. Good luck with that! 📈 Here is some real world data from a 90kW motor with a bearing defect at the DE. The best parameter you can trend a bearing defect is Waveform P-P in G's so I have set my 2140 to live monitor the time waveform over 10kHz fmax. Note a P-P level of around 38G's PK-PK at the DE bearing. I then do a comparison by moving my sensor to the middle of the motor with levels dropping to around 4 G's PK-PK a massive difference. So why am I seeing sensors placed in these locations? 📚 Unfortunately many clients do not have the background vibration knowledge required for these systems to be implemented correctly. Worst still its company's promoting these systems with salesmen who don't have a clue either. Trying to get the sale by saying only one sensor is needed to keep costs down when two are required." 🔎 For helpful resources see the comment below. #vibrationanalysis #conditionmonitoring #reliabilityengineering #wirelesssensors #ams2140
