With 4-20mA loadcells it is not so straight forward, we commonly would not expect to see a difference in the site zero kN applied load and the calibration zero kN applied load, outside the accuracy of the sensor. If a difference is present and this is required to be removed, this difference would require to be calculated into KN and removed after all future readings are calculated into KN, rather than removal within the engineering calculation.
We can confirm that the temperature effect on the Strain gauge load cells from -10°C to +50°C is +/- 0.005% FS/°C. The temperature effect is therefore well within the sensors accuracy, please see the datasheet attached. In summary no temperature effect to worry about. | |
