Test set-up
Connect pin (4) to ground and connect pin (5) to positive side
of voltage supply Us. 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.
