hi ,
may i know how to convert voltage to acceleration ? i using picoscope 3000 series and accelerometer with sensitivity 9.9 mv/g . i really need help

9.9mV = 1G
-9.9mV = -1G
99mV = 10G
99000000000mV = 10000000000G
What kind of help you need?

if my output is 3.3 mv from the screen. then i just divide the sensitivity of accelerometer sensor to get acceleration ??
for example
g= 3.3 mv/ 9.9 mv/g = 0.3333 ??
if that correct ???

If you import the attached probe into the PicoScope software it will do this all for you.

hi
if i attached the probe inside..
how that tool detect my sensitivity of sensor ?
i use 3 channel with different sensitivity
?

is it we picoscope will automatically detect the sensitivity of accelerometer once i attached that acceleration probe ?

The following may prove to be an interesting read for you although it is related to testing Pine not Steel but the principals should be the same
http://www.fwpa.com.au/sites/default/fi ... OE_MOR.pdf
It uses the following kit
A Laptop or Desktop
B Data acquisition card (Pico Technology Type Picoscope 3224)
C Accelerometer (Brüel & Kjaer Type 4397)
D Impact hammer (Brüel & Kjaer Type 8206-2)
E Conditioner (Endevco Type 4416B) for accelerometer and impact hammer
F Low pass filter to avoid aliasing effect
G Screw for the accelerometer attachment (magnet system)

hi martyn,
if i divide sensitivity of sensor by voltage AC RMS will get acceleration RMS ??
got any paper or journal to prove ? i really need that . thanks

hi martyn ,
do u have any journal or technical paper to show whether need to consider accelerometer sensitivity by using acceleration probe u upload ?

Not sure why you need a paper for this.
An accelerometer will produce a voltage relative to it's acceleration. The manufacturer of the accelerometer will give details of this relationship. All the probe I have produced does is to display the actual acceleration rather than the voltage, it simply does the mathematical conversion for you.

Hi,
I've been trying to load your psmaths into the Software, but it doesn't working. The screen after "Import" is still without the psmaths file. What went wrong ?
Thanks&Greets

As you have come in on a very old thread the advice may not be relevant to your version of the software.
What version are you using ?
What device do you have ?
What sensor are you using ?
