Read Static Force from Dynamic Sensor

[Shazlan]

Hi,

I have several ICP dynamic force transducers. The previous application involved high frequency delta F (changes in force) and thus, making the sensor appropriate to be used.

Now, our new project requires force measurements but the changes are slow. Ideally, we would want to get some load cells but this project is operating at a very tight budget. Thus, we are asked to make use of the dynamic force transducers from the completed project above. The problem that I am facing is to record and display the force readings without the 'time-discharge' measurements - Sorry, I'm not very sure how to put this but I guess those who have used similar sensors would understand what I meant. I was told to simply read the peak values and ignore the decrease values (increase values, if the peak is negative) heading towards zero  but I found out that this approach is not accurate for low frequency changes - It is relatively accurate only for static measurement.

Assistance are highly appreciated, thanks.

Hi Shazlan,

I am not too familiar with the type of sensor you are using, but I would like to help.  Do you have any more information about the transducer (spec sheets or whatnot)?  I was not able to find anything close just searching the internet.

Also, maybe a screenshot of what you are seeing and what the input was may give me a better idea of what you are dealing with.

In college I was able to make my own load cell for tension with a strain gauge on a known material (F/A = σ = Eε), I dont remember exactly what we did, but it worked alright...
