I have an application for a scale. The scale has 4 load cells 500lb @ 3 mv/v using a constant 10v excitation. I'm using a 0 -20 ma 433
BridgeSensor (from TotalComp) to convert the loadcell signal. The BridgeSensor has calibration parameters to Zero and Span its output signal I don't have any numbers on the physical weight of the scale vessels. Should I accommodate this weight in my calibration of the signal or should I set the 0 with the vessels empty? If I need to
accommodate the weight how do I determine this accurately using the loadcell raw output? In my program ( RsLogix 500) I'm using the Scale with Parameters instruction to achieve calibration based on my ma signal but I feel that the hardware calibration needs to be properly setup
first. Any discussion or further related information would be greatly appreciated.
Thanks in Advance.
