Jan 13, 2016 · 2. Extech's VB300 Vibration Recorder. The VB300 is a very cost effective vibration measurement instrument and is an entry level vibration recorder. Coming in at less than 300 it can be a great first option at quantifying your vibration environment. It's definitely limited in sample rate (up to 200 Hz) and total storage (4Mbit or 112K samples per axis) but for some applications this as adequate.

Jun 10, 2001 · ive had a reading of about 24 MILS on a TF-39-c the max reading is 18mils for fan and 10 mils for core. we shut the engine down inflight and you could really feel it. one of the weights in the fan came loose and caused the vibes. for MINUTEMAN there are proceedures to tie the fan down and run the engine to check for leaks and such but you have a time limit on how long you can do this for.

Summary of Amplitude Units: - Vibration Analysis

Summary of Amplitude Units: - Vibration Analysis

Summary of Amplitude Units: In the English system of measurements, displacement is usually measured in mils (thouhs of an inch), and the peak-to-peak value is used by convention. Velocity is usually measured in inches per second, and the convention is to use the peak value or the RMS value. The peak value is the most commonly used, not because it is better, but because of long tradition.

Why is Vibration Amplitude in G? - Precision Microdrives

Vibration motors are not used on their own – they're attached to a product/device/piece of equipment that is intended to vibrate. Therefore we are interested in the whole system (motor + target mass). We measure the vibration amplitude by mounting the motor on a known target mass and reading the results from an accelerometer, see more here .
