Emerson Rosemount 5300 Series - Page 297

Rosemount 5302 with the large coaxial probe provides the ability to continuously keep
track of both level and interface level in fully submerged applications. The product level
and interface level mode must be selected.

If interface is to be measured, follow these criteria:
• The dielectric constant of the upper product should be known and should not vary. The
Rosemount Radar Master software has a built-in dielectric constant calculator to help
the user estimate the upper product dielectric constant.
• The dielectric constant of the upper product must have a lower dielectric constant than
the lower product to have a distinct reflection.
• The difference between the dielectric constants for the two products must be larger
than 6.
• The maximum dielectric constant for the upper product is 7 for the single lead probes,
10 for the coaxial probes, and 8 for the twin lead probes.
