Explanation
1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device
depends on the lowest-rated element, with regard to pressure, of the selected
components, i.e. the process connection has to be taken into consideration in
addition to the measuring cell. Also observe pressure-temperature dependency.
For the relevant standards and additional notes, see the "Pressure specifications"
section → 130.
The OPL may only be applied for a limited period of time.
2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-
rated element, with regard to pressure, of the selected components, i.e. the
process connection has to be taken into consideration in addition to the
measuring cell. Also observe pressure-temperature dependency. For the
relevant standards and additional notes, see the "Pressure specifications" section
→ 130.
The MWP may be applied at the device for an unlimited period.
The MWP can also be found on the nameplate.
3 Maximum sensor
measuring range
Span between LRL and URL
This sensor measuring range is equivalent to the maximum calibratable/
adjustable span.
4 Calibrated/
adjusted span
Span between LRV and URV
Factory setting: 0 to URL
Other calibrated spans can be ordered as customized spans.
