FEATURES AND
APPLICATIONS
Rosemount Analytical sets a new industry standard
for the life expectancy of pH and ORP sensors with
the introduction of our TUpH Sensors. These low
maintenance, disposable sensors offer long life and
high performance in the measurement of pH in aqueous solutions in pipelines, open tanks or ponds.
The TUpH Sensors feature a patented large area
polypropylene reference junction for maximum resistance to process coatings, generally found in dirty, high
solid applications. In addition, the patented secondary
helical reference pathway serves as added protection
from poisoning ions.
Our TUpH Sensors also feature a standard 1 in. outer
diameter for versatile mounting in flow through, insertion or submersion pH and ORP applications.
The Model 396 Sensor is
specifically designed for
improved life in harsh, dirty,
and abrasive applications
such as lime slurry waste
treatment, paper machine
headbox and pigment/dye applications, where large
quantities of suspended solids are present.
The Model 396 is available with custom glass electrodes, optional flat or standard hemi glass pH bulb,
to best meet your application needs. Flat glass is
advantageous in abrasive or coating applications that
etch or build up on glass respectively. In coating applications, such as slurries, the flat surface allows the
process flow to act as a scrubbing agent to reduce
coating and maintenance whereas in abrasive applications pitting from silicates and other similar materials is minimized by the flat surface to provide longer
life. The hemi bulb is ideal for general purpose use
and for those processes requiring greater accuracy
over the entire pH range.
The sensor is housed in a stainless steel body with
EPDM seals. The simplified construction, designed
with user convenience in mind, does not require electrolyte replenishment or any component replacement. The Model 396 also features a large glass bulb
for increased resistance to high temperature and
other effects of aging for longer life.
The Model 396 is not available with an integral preamplifier. The preamplifier must be in a remote location or integral to the analyzer/transmitter. Therefore,
the Model 396 is compatible with all Rosemount
Analytical and other manufacturers’ instruments.
The Model 396P Sensor is
specifically designed for improved
life in harsh, dirty applications,
such as sour water waste treatment and scrubbers, where a high
performance, low maintenance,
disposable sensor is required.
The sensor is available in two configurations: the standard shrouded tip, in which the pH glass is completely
recessed within the reference junction for abrasive or
rough applications, and the optional slotted tip with a
partially exposed pH glass for viscous or low flow
applications.
The Model 396P features a titanium solution ground,
constructed in an annular design around the pH/ORP
electrode. The solution ground provides advanced
sensor diagnostics for preventative maintenance when
used with the Models 54 pH/ORP analyzer, 1054B
pH/ORP analyzer, and 3081 pH/ORP transmitter. In
addition, the Model 396P sensor can be used with
most non-diagnostic Rosemount Analytical and other
manufacturers’ instruments.
The sensor is housed in a molded polypropylene body
with EPDM seals, making it virtually indestructible and
chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally
found in other pH/ORP designs. The simplified construction, designed with user convenience in mind,
does not require electrolyte (KCl) replenishment or
any high maintenance troubleshooting procedures.
The Rosemount Analytical Model 396P is available
with an optional integral preamplifier to convert the
high impedance pH or ORP mV signal into a stable,
noise-free signal with transmission capability of up to
three miles.

The Model 396R
Sensor is specifically
designed for improved
life in harsh, dirty applications where a separate sample stream is
difficult to provide and
greater insertion depths
are required. It is designed for use with a 1-1/4 in. or
1-1/2 in. ball valve for hot tap installation.
The Model 396R is constructed of molded polypropylene housed in a titanium tube with EPDM seals to
provide maximum chemical resistance. The sensor
also features a titanium solution ground for advanced
sensor diagnostics when used with the Model 54 or
Model 3081 pH/ORP Analyzer/Transmitter. These
Rosemount Analytical 3
advanced sensor diagnostics provide preventative
maintenance by notifying the operator of the need for
replacement and cleaning of an aged or fouled sensor,
thus allowing continuous optimum performance.
The sensor also features a slotted tip for protection
from breakage while allowing the process to flow by the
glass electrode for accurate and reliable pH measurement.
The Model 396R is only available without an integral
preamplifier and has 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 junction box kit for attachment at the rear, cable end of the sensor (order separately) or must be integral to the Analyzer/Transmitter.
The Model 396R is compatible with all Rosemount
Analytical and other manufacturers’ instruments.
