Are the iLoad Series capacitive load cells temperature compensated?
The iLoad Series load cells are temperature compensated in the operating temperature range if the rate of change of temperature is gentle (less than 1 degree C per minute). Sudden changes in temperature (“thermal shock”) can cause temporary compensation errors. Despite the compensation scheme, however, due to accumulation of errors over a period of time, errors can add up to several percentage of full scale if used without “tare” over a few days. Long term stability is very difficult to achieve under changing thermal conditions, so we recommend periodic ‘tare’ on the load cells to reset the zero value at the new temperature condition. If your application requires accuracies better than +/- 1% WITHOUT tare over long periods of time, then please use one of our NTEP approved load cells. These resistive load cells have the best performance WITHOUT tare and under varying temperature conditions.
