Let's talk over one example for the sensor label reading.
When you get a Range 4 pressure transmitter, you know that according to the catalog this device is specified to work from -14.5 to 360 psi.    However, when I look at the transmitter sensor label you could see two different notations.
1) If the transmitter is relatively new you will see the same thing: -14.5 to 360 psi. Great no confusion! This is the working range for this pressure transmitter.
2) In the other way, you can see: 0.625 to 25 bar.  This is an old notation for the sensor label.
If you convert from bar to psi you will see that this will be around 9 psi to 360 psi. Still, that looks wrong!! How about the negative pressure!!!
This notation is not about the working range of the transmitter, instead it shows the smallest possible working span (9 psi) and the maximum working pressure (360 psi).
So, you can relax, this is the same range that you have purchased, just with other interpretation.
