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 calibrate with positive up and cable connected to P5000 with the relevant transducer class chosen.

Go to Single Channel Calibration screen.

Click on the Tone tab.

With P5000 armed turn on the shaker and monitor the sine wave on the real-time monitor and check Signal Quality as being GOOD.

With a GOOD sine wave click the Calculate button. It is recommended to click Calculate three times.

Check to see the Sensitivity change from what was originally entered when setting up the channel transducer information to the new calculated value. The calculated value should be close to the original.

DC Cal Offset is for DC level accelerometers.

Requested Excitation is for non IEPE (ICP) accelerometers such as capacitive.

After calculating the new sensitivity click on the Use button to make the change in the Transducer Sensitivity Acquisition Setup file.

NOTE: To achieve a GOOD signal reading place the shaker on a flat surface and avoid touching during operation. Make sure the surface the shaker is sitting on does not come in contact with other sources of vibrations or electrical conductance.

And The Winner Is…

Thank you to everyone who completed our 2012 User Survey. The results were, as always, fascinating and will be used to improve our future hardware & software products.

We are please to announce that James Hansen of Ford Motor Company was the winner of the prize draw for a Kindle Touch. James is a veteran of Prosig hardware & software and has seen several generations of both. Here is James receiving his Kindle from Ken Goward of Prosig USA…

Congratulations to James. We hope you enjoy your Kindle.

Bad luck to all our other respondents. There’s always next year’s survey…

What is the difference between Operating Deflection Shapes (ODS) and Operational Modal Analysis (OMA)?

ODS = Motion of structure vibrating naturally (for example bridge vibration) or when excited by an unknown force (for example generator vibration). Prosig’s Structural Animation software performs ODS analysis.

OMA = Modal Analysis
Prosig’s Modal Analysis software performs OMA. Continue reading What is the difference between Operating Deflection Shapes (ODS) and Operational Modal Analysis (OMA)?

Using global variables, variable arithmetic & script fragments

One of Prosig’s engineers was recently creating a complex worksheet application that required some complicated arithmetic to be performed on values calculated in the worksheet. Worksheet (or global) variables are ideal for this. The Variable Mods DPU also has an expression evaluator built in. Consider the following worksheet that takes a Named Element from two signals and sums them. Continue reading Using global variables, variable arithmetic & script fragments
