Question:  How do you verify the performance or accuracy of a vibration monitoring system or an actual sensor? Answer:  A Portable Vibration Shaker 

There are various methods of simulating a vibration signal, some involving the simulation of the electronic signal, and others involving an actual mechanical vibration signal to a sensor. 

These vibration simulations devices are called Shakers and are found in various shapes in sizes.   Testing laboratories often use a large (and costly) shaker table with all of the appropriate software and hardware.  These large shaker tables cannot be transferred to the field, however, which is where system calibration often needs to be performed.

There are also fixed frequency hand-held shakers on the market that allow the user to verify the output of a sensor at a fixed frequency and amplitude. 

The most user-friendly shakers are those that combine reliable and accurate technology with a ruggedness and portability to travel anywhere, anytime.  The Hardy line of shakers covers the spectrum for Portable Shakers - from Fixed Frequency, variable amplitude (HI 823), to a variable frequency variable amplitude (HI 813), to variable frequency, variable amplitude and sensor verification and reporting capability (HI 803).

With a portable (battery-powered) shaker, you can travel to a monitoring location, input a vibration signal signal at the appropriate amplitude in g's, ips, or mils, at the appropriate frequency (from 10hz to 10khz), and verify the sensor output.
