Does Prosig hardware support strain gauges? And which types?
I’m often asked whether the Prosig systems support strain gauges. And what configuration of strain gauge bridges are supported? The answer is all types of all configurations. (more…)
How Do I Calibrate An Impact Hammer?
The intention of this article is not to present any new scientific theories or ground breaking techniques, but to introduce new users to hammer impact testing and remind seasoned technicians of a method…
How should the bridge factor be selected when using strain gauges?
The number of active arms in a strain gauge Wheatstone bridge is known as the bridge factor.
As a simple guide when selecting bridge factors the following rules apply; (more…)
Calibrating an Accelerometer with a Prosig P5000 system
Here we look at how to calibrate an accelerometer using a Prosig P5000 system. Put the wax on the shaker top. Place the accelerometer in the axis you wish to…

Non-Linear Calibration Curve And Polynomial
Not all systems vary linearly. One very well-known case is, of course, thermocouples. International standard curves are available for these, so they present little difficulty. The issue discussed here is determining a non-linear calibration curve and, if appropriate, reducing it to a polynomial.
