Rosemount 5300 Series
A short weight for the single flexible 0.16 in. (4 mm) SST probe can be used
for measuring close to the probe end. The height is 2 in. (50 mm) and the
diameter is 1.5 in.
(37.5 mm). Option code W2.
For hot applications, the chamber should always be insulated to prevent
personal injuries and to reduce the amount of energy needed for heating. See
Figure 3-6. It is often an advantage, and sometimes even required, for the
radar measurement:
• In hot applications, insulation reduces the amount of condensation,
since it prevents the upper part of the chamber from becoming a cold
spot
• Insulation prevents product solidification inside the chamber, and
clogging of the inlet-pipes

When mounting in a Rosemount 9901 chamber, the probe length to use can
be calculated with these formulas:
Side-and-Side dimension: Probe length = Centre-to-Centre dimension +
19 in. (48 cm)
Side-and-Bottom dimension: Probe length = Centre-to-Centre dimension +
4 in. (10 cm)
