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
→ 38.
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 → 38.
The MWP may be applied at the device for an unlimited period.
The MWP can also be found on the nameplate.

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.

- LRL Lower range limit

- TD (turn down) Turn down
The turn down is preset at the factory and cannot be changed.

2 Zero-based span
3 URL sensor
Example
• Sensor:10 bar (150 psi)
• Upper range value (URL) = 10 bar (150 psi)
Turn down (TD):
• Calibrated/adjusted span:
0 to 5 bar (0 to 75 psi)
• Lower range value (LRV) = 0 bar (0 psi)
• Upper range value (URV) = 5 bar (75 psi)
TD = URL
|URV - LRV|
TD = 10 bar (150 psi) = 2
|5 bar (75 psi) - 0 bar (0 psi)|
In this example, the TD is 2:1.
This span is based on the zero point.
