We have a loadcell, the output of which is (naturally) temperature dependent. Under static load conditions, we have observed a dynamic response to temperature changes. Therefore, we did a step response experiment by placing the device in a -20 degree (C) freezer and then transfering it to a 40 degree (C) climate chamber.
What we see is that the temperature of the loadcell has a first order response and the loadcell output has a second degree response (under damped).
What we want to do now is to correct the temperature dynamics induced loadcell output error by using the temperature signal.
How can we use the results we obtained from the step response to correct the weight output when the temperature changes in real time, given temperature and loadcell output signals?
