1 OPL: The OPL (overpressure limit = sensor overload limit) for the 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. Pay attention to the pressure/temperature dependency.
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. Pay attention to the pressure/temperature dependency. The MWP may be
applied at the device for an unlimited period of time. The MWP can be found on the nameplate.
3 The maximum sensor measuring range corresponds to the span between the LRL and URL. This sensor
measuring range is equivalent to the maximum calibratable/adjustable span.
4 The calibrated/adjusted span corresponds to the span between the LRV and URV. Factory setting: 0 to URL.
Other calibrated spans can be ordered as customized spans.
