2. Safety
2.1 Pressure ranges
The permissible pressure range for the pressure transmitter can be found on the product label.
WARNING!
■ The overload pressure must never be exceeded, even when failures occur. Loading over the overload
pressure can cause measuring errors in the output signal and thus impair the safety function.
■ Pressure surges below the nominal pressure and lasting less than 1 ms can cause measuring errors
in the output signal and thus impair the safety function. For this, optional pressure ports with a smaller
diameter are available to reduce pressure surges. It is important to ensure that the reduced diameter
is suitable for the particle sizes within the medium.
