We are trying to conduct a quick structural test in which we will need a load cell. I either need to figure out what basic display I can use with the cell or possibly just drive it with a power supply and read from my precision DMM? Obviously I would just have to convert the mV readings to force but there is some talk about possibly accuracy issues? Need filtering?
All the gadgets I find on ebay and such seem to just be basic PID controllers that seem to to little more than provide a power supply and convert the signal return to a force value?
I am trying to get more info on the load cell we want to use but appears to have 5-6 ranges of measure so I am not sure how they set that up in the device but I assume there is a pin or wire output for each range using either a separate strain gauge in the device or they have separated zones or something.
