Interpretation of the sensor data

3.2.1

Pressure

The conversion of the digital values to decimal pressure values is realized by a linear function defined
by two points (P
P[u15]
P : 3277 (10 % of 15 bit)
10%
P : 29491 (90 % of 15 bit)
90%
The minimum and maximum pressure values are stated in the order confirmation. Additionally, the pres-
sure range of the digital pressure measuring cell is stored in its memory and can be read by the software
(see chapter 4.6.1 "Sensor details", Page 22).
The output range is 10 % to 90 % of the 15 bit data. This way concurrently over- and underpressure is
measurable and the resulting 26214 full scale guarantee a very high resolution.
Calculating pressure value
In standard configuration the actual pressure can be calculated with the following formula:
MSP (measuring span) = P
