How To Measure High G Force Decceleration and Acceleration During Shock or Drop Testing

There are of course very expensive instruments available for measure the high g forces for impact testing. Most inexpensive accelerometers or inertial measurement units only measure up to 16G of acceleration. We had an application that required measuring 150G during a shock test. We wanted something simple, and preferably wireless (bluetooth).


This article describes a simple method of how to calculate the G-force of a drop impact. The impact velocity is calculated from acceleration of gravity.


These are some of the devices I found that fit the application needs and were still relatively low cost.







WHICH ONE DID I CHOOSE?
