Item Term/abbreviation 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.
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.
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.
