6. Select the TRANSDUCER1100 block and choose the Probe tab.

FOUNDATION Fieldbus parameters:

TRANSDUCER 1100>PROBE_TYPE TRANSDUCER 1100>PROBE_LENGTH TRANSDUCER 1100>GEOM_HOLD_OFF_DIST

Check that the correct Probe Type is chosen. Normally, the Probe Type is pre-configured at the factory, but if the current configuration does not match the actual probe, choose the correct Probe Type from the list.

The Rosemount 5300 Series transmitter automatically makes some initial calibrations based on the chosen Probe Type. The following probes are available:

•Rigid Twin

•Flexible Twin

•Coaxial, Coaxial HP, Coaxial HTHP

•Rigid Single, Rigid Single HTHP/HP/C, Rigid Single PTFE

•Flexible Single, Flexible Single HTHP/HP/C, Flexible Single PTFE

The Probe Length is the distance from the Upper Reference Point to the end of the probe, see Figure 5-1.If the probe is anchored to a weight do not include the height of the weight. The Probe Length needs to be changed if, for example, the probe is shortened.

The Hold Off Distance/Upper Null Zone (UNZ) should not be changed unless there are disturbances at the top of the tank. By increasing the Upper Null Zone, measurements in this region are avoided. See “Handling of Disturbances from Nozzle” on page C-4for more information on how to use the UNZ. The UNZ is equal to zero in the factory configuration.
