hi All, Newbie with Load Cells here,
first a brief explanation of what I'm trying to accomplish, we are integrating a Dynamic impact test, in other words we use a pendulum machine. we lift the pendulum which have a mass aprox of 100 Kg, then we release the pendulum impacting the item under test, we use a load cell to read how much force the item under test resist before breaking.
I'm using a Sensotec load cell with a 10,000 LBS range and an output of 3mV/V, the excitation is 10V then the max output will be 30 mV at a max load.
on the other hand I'm using a NI PCI DAQ board 6221 with an SCC-68 connector block and one SCC-SG24 full bridge, 10 V excitation module for signal conditioning and to read the input signal. the following are the LC readings when applying different loads.
no load applied= 0.8 mV
500 K/g F=3.4mV
750 Kg/F=5.0mV
1000Kg/F=6.4mV
I did verified the DAQ readings with a Multimeter and they are the same so, I'm assuming my DAQmx Task configuration for read the LC is correct.
here is the question: How can I convert those mV readings onto Force????
in other words how can I scale my mV readings to represent any force applied to the Load Cell???
any help would be greatly appreciated.
MG.
