3.3.4. High Calibration Pt. (default 0.350 m)
Distance from Sensor Reference to High Calibration Point (corresponding to High
Level Point). Unit is defined in Sensor units.
3.3.5. Unit (Level)
Selected engineering units for Level (PV), referenced from Low Level Point (plus
level offset, if any).
3.3.6. Low Level Point (default 0.000)
The level when the material is at Low Calibration Point. The unit is defined in Level
units.
3.3.7. High Level Point (default 100.000)
The level when the material is at High Calibration Point. The unit is defined in Level
units.
3.3.8. Level Offset (default 0.000)
A constant offset that can be added to Level to form PV/SV! (default level output).
See page 101 for an illustration. The unit is defined in Level units.
3.3.9. Sensor Offset (default 0)
The offset from the Sensor’s reference point to the vessel’s reference point. This
is a constant offset that is subtracted from the Sensor value. The unit is defined in
Sensor Units. (See How the Level Transducer Block works: on page 100 for
further details.)
Compensates, for example if the sensor head is changed.
3.3.A. Temperature Units
Selects the engineering unit to be displayed with the value representing
temperature.
