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.

Measuring Vibration - Page 6

Pure sinusoids are rarely encountered in the world of mechanical vibration. Due to that, the trend amplitude value is calculated by simply multiplying the peak amplitude by 0.707. But some analysts prefer to display the amplitudes as a 'peak' amplitude (usually because the vibration severity charts they are using are in peak amplitude values).

12. VIBRATION ISOLATION

vibration amplitude. A curious effect of damping is that it results in increased amplitude at frequencies > 1.4 f n. Examples: 1) Calculate the transmissibility at 60 and 120 Hz for a 20,000 lb chiller unit supported by eight springs with 3" static deflection. Answer: Frequency – Hz r T dB % Isolation 60 60/1.8 = 33.33 .0009 30.5 99.910%
