. Apply test pressure to sensor (input 6)
Take reading of output voltage between pin (4) and pin (3).
Divide the measured output voltage (Ua) by the supply voltage
(
Us
).
◆
NOTE: Calculation of this pressure ratio is required
since the diagram is effective over a whole
voltage range and not just for a single voltage.
Enter this value in the table Ua/Us. A pressure can be read off
at the intersection of the straight lines.
Max. deviation ± 40 hPa

CAUTION: In the event of physical damage or resistance
readings outside allowance, replace the part
without delay.
