While basic theory is reviewed for enhancement of conceptual understanding, focus is on leading the practicing engineer or technician to clearly grasp of the types of vibration and shock that can be imparted to a product, sources of vibration and shock requirements, available test equipment, and correct interpretation of data. A shock data logger or vibration data logger is a measurement instrument that is capable of autonomously recording shocks or vibrations over a defined period of time. Digital data is usually in the form of acceleration and time. The shock and vibration data can be retrieved (or transmitted), viewed and evaluated after it has been recorded.
An accelerometer is a device that measures acceleration (G-force). When stationary, it will measure the force of gravity, or m/s2. When vibration is detected, it will output a voltage based on its sensitivity rating. Some of the popular types of sensors include piezoelectric. Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or.
As in vibration isolation systems, the resilience (stiffness) and the extent of damping built into an isolator are the main parameters affecting the performance of a shock isolation system. The Impact of Isolator Parameters on Shock Isolation The two traces in Figure 6 show the displacement (a) and the acceleration (b) responses of a Kg. Two easy-to-set dials allow you to adjust a set activation point for vibration as well as a time delay to avoid false triggering from start-up vibration. An alarm signals if the set activation point is exceeded. Plug the included cable into your data collector or programmable logic controller. IP67 rated for protection from dust and water.. Use an optional magnetic base for temporary mounting.

Vibration testing, on the other hand, determines the extent to which items can withstand mechanical vibrations.
Mechanical Shock Testing. Mechanical shock testing typically involves subjecting a test device to sudden and extreme amounts of acceleration or deceleration while instrumentation, such as strain gages, load cells, piezo sensors and more.
In this relationship, the bias (b) represents the value of the sensor’s output when it is experiencing zero linear vibration (or any type of linear acceleration).
The scale factor (K A) represents the amount of change in the MEMS accelerometer’s response (y), with respect to the change in linear acceleration (a).
