HP03 Series of calibrated sensor module

Version: 1.3
Pressure and Temperature Measurement
The main function of HP03 system is to convert the uncompensated pressure and
temperature signal from a pressure sensor. After the conversion, the following two values
can be obtained:
. measured temperature
“D2”
. measured pressure
“D1”
As the sensor is strongly temperature dependent, it is necessary to compensate for these
effects. Therefore 10 sensor-specific coefficients are stored on the HP03 at our
manufacturing facility, and they allow an accurate software compensation in the
application.
The 7 coefficients are:
. Sensitivity coefficient
. Offset coefficient
. Temperature Coefficient of Sensitivity
. Temperature Coefficient of Offset
. Reference Temperature
. Temperature Coefficient of Temperature
. Offset Fine Tuning

“C4”

Note: Make sure to pull low XCLR before start to Read these coefficients or the data read
out is probably incorrect
