1. Should I order a calibrated sensor?
Standard uncalibrated sensors are somewhat non-linear and hence the relationship of applied force against output does not follow a straight line and in fact is curved (Left Image). Furthermore, a standard sensor’s full-scale output is only approximately in-line with the full-scale load.
Calibrating the sensor linearizes the output and ensures that the full-scale output matches full-scale input with a maximum deviation of 2%. See example below (Right Image).
