2.5
The accuracy of the KP229E3518 sensor is influenced by the supply voltage (ratiometric error) as well as by
pressure, temperature and aging effects. The specified value, calculated with the transfer function, represents the
theoretical value (see
the specified output voltage value.
2.5.1
Ideally the sensor is ratiometric - the output (V
ratiometric error is defined as the difference between the ratio that
expressed as a percentage.

Overall accuracy covers the entire pressure and temperature range from different sources of error including the
following:
•
Output deviation from target transfer function over the specified pressure range
•
Output deviation over the temperature range
•
Parameter drift over life time
