Vibration meter is offered by baseline technologies. Model 2050 has some technical features which include: a compact hand-held instrument, suitable for general purpose vibration measurement on rotating machinery. It can measure rms vibration velocity in mm/sec; in addition to pk-pk displacement in microns and rms acceleration in the is/iso specified frequency band of 10 hz- 1,000 hz. In the bearing mode, it measures bearing spike, which is the high frequency vibration emitted typically by faulty bearings. Vibration sensor-an accelerometer has no moving parts, and integral amplifier, so that there is absolutely no effect of cable shake on the measured readings; thus it provides a very sound basis for monitoring the state of bearings in an objective manner;from in-built rechargeable ni-mh batteries, this machine is operated.
