Shock and vibration data logger
open-in-new
<p>A shock data logger or vibration data logger is a <a href="/facts/Measurement_instrument/gfkMHBNR">measurement instrument</a> that is capable of autonomously recording <a href="/facts/Shock_(mechanics)/AjThlASN">shocks</a> or <a href="/facts/Vibrations/sGgDqG71">vibrations</a> over a defined period of time. Digital data is usually in the form of <a href="/facts/Acceleration/UVDmjYvR">acceleration</a> and time. The shock and vibration data can be retrieved (or transmitted), viewed and evaluated after it has been recorded. </p><p>In contrast with a shock data logger, a <a href="/facts/Shock_detector/KojtvoYW">shock detector</a> is used to indicate whether or not the threshold of specified shock has occurred. </p>
