1.1 FEATURES AND APPLICATIONS
The Model 396R and 396RVP Sensors are specifically
designed for improved life in harsh, dirty applications where
a separate sample stream is difficult to provide and greater
insertion depths are required. Model 396R is designed for
use with a 1-1/4 in. or 1-1/2 in. ball valve for hot tap installa-
tion. The Model 396R is constructed of molded polypropylene
housed in a titanium tube with EPDM seals to provide maxi-
mum chemical resistance
2,3
.
Model 396R also features a titanium solution ground for
advanced sensor diagnostics when used with the Models
1055, Xmt-P, 54e, 81, 3081, or 5081 pH/ORP Analyzer/
Transmitter. Advanced sensor diagnostics provide preventa-
tive maintenance by notifying the operator for replacement
and cleaning of an aged or fouled sensor for continuous
optimum performance.
The sensor also features a shrouded tip for protection from
breakage while allowing process to flow by the glass elec-
trode for accurate and reliable pH measurement.
The Model 396R is available without an integral preamplifier
only and 15 ft or 9.5 in. of integral high quality 9 conductor
cable. The preamplifier must be housed in a remote location
or in a J-Box kit for attachment at the rear, cable end of the
sensor (order separately) or integral to the Analyzer/
Transmitter. The Model 396R is compatible with all
Rosemount Analytical and various other manufacturers
instruments.
The entire line of TUpH model sensors now incorporate
the new SILCORE
1
technology contaminant barrier. This
triple-seal barrier prevents moisture and material impurities
from migrating to the pH sensor’s reference electrode’s metal
lead wire. By preventing these contaminants from compro-
mising the integrity of the pH measurement, sensor life is
increased, especially at higher temperatures where
increased migrations occur. In addition, the SILCORE tech-
nology provides added protection against sensor failure due
to vibrations and shock by transferring damaging energy
away from the glass-to-metal seal.
Model 396RVP: Rosemount Analytical has recently released
Model 396RVP. This model has identical performance and
physical specifications to the Model 396R (see Section 1.2)
with the following exception: the Model 396RVP has a
Variopol (VP) connector on the back end of the sensor in
place of a cable.
