This set of parameters within the Transducer Block is impor-
tant and required to configure every Eclipse Model 705
transmitter.
PROBE_MODEL: Select the choice that corresponds to the
first four digits of the model number of the probe. An “x”
in the selection means that character is variable (the probe
model number is shown on the nameplates attached to both
the transmitter and probe). For example, 7xA-x should be
chosen for probe models beginning with 7EA or 7MA.
PROBE_MOUNT: Select the type of mounting on the
probe. The choices are NPT, BSP, and Flange.
MEASUREMENT_TYPE: Select from LEVEL ONLY,
LEVEL AND VOLUME, INTERFACE, or INTERFACE
AND VOLUME.
PROBE_LENGTH: Enter the exact length of the probe.
The probe length is shown as the last three digits of the
probe model number printed on the nameplates attached to
the transmitter and probe. PROBE_LENGTH is shown in
SENSOR_UNITs.
LEVEL_OFFSET: Enter the distance from the probe tip to
the desired 0% reference in PROBE_LEVEL_UNITs. The
acceptable range is from -300 inches to 600 inches. Refer to
Section 4.3.4 for additional information.
DIELECTRIC_RANGE: Select from 10–100, 3–10, 1.7–
3.0, or 1.7–1.4
NOTE: All dielectric ranges are not available with all probes.
If an unsupported dielectric range is selected, the transmitter
will give a negative response and the value displayed will
revert to its previous value.
THRESHOLD: The threshold can be set as either FIXED
or CFD. The factory default is CFD. This parameter should
only be changed to FIXED in those applications measuring
total level having a lower dielectric material over a higher
dielectric material. A typical example for FIXED Threshold
is a hydrocarbon application having water bottoms.
