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/

Span between LRV and URV

Factory setting: 0 to URL

Other calibrated spans can be ordered as customized spans.

- LRL Lower range limit

The turn down is preset at the factory and cannot be changed.

1 Calibrated/adjusted span

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.
