2.4
The KP229E3518 device is fully calibrated on delivery. The sensor has a linear transfer function between the
applied pressure and the output signal:
The output signal is ratiometric. Gain a and offset b are determined during calibration in order to generate the
required transfer function.
Calibrated Transfer Function
The following calibration is adjusted with the parameters a and b:
