Rosemount 5300 Series

A long stud - 10 in. (250 mm) - is recommended for single flexible probes in a

tall nozzle.

Figure 3-3. A single flexible

probe with a long stud.

NOTE!

For single lead probes, avoid 10-in. (250 mm)/DN250 or larger diameter

nozzles, especially in applications with low dielectric constant. An alternative

is to install a smaller nozzle inside the nozzle.

Installation of Single

Lead Probes in

Non-metallic Vessels

For optimal single lead probe performance in non-metallic (plastic) vessels,

the probe must be mounted with a metal flange, or screwed in to a metal

sheet (d>8 in./200 mm), if the threaded version is used.

Figure 3-4. Mounting in

non-metallic vessels.

Electromagnetic disturbances should be kept to a minimum since they may

affect measurement performance.
