Vibration monitoring
What the ground does when a blast fires, how a unit records it, and how to read the numbers.
Displacement
How far the ground moved from rest — usually a fraction of a millimetre.
StartVelocity
How fast the ground is moving at each instant. Compliance limits are written in mm/s.
StartAcceleration
How fast the velocity is changing. This is what a ViB accelerometer senses.
StartFrequency
How many cycles a second. The same travel is a different speed and a different g at a different rate.
StartRead a real record
A real blast is many tones at once, so the trace is messy. The pure tone is the building block, so you can check the sums.

StartSetting a ViB up for a blast
Pick the job, read the numbers it needs, and know what the unit will do when the shot fires.
StartAcceleration and velocity
Your trigger is set in g. Your limit is written in mm/s. See where the two meet, at the frequency your site actually produces.
