1.1Features and Applications
TUpH™pH/ORP-sensors are now offered with SMART capabilities. SMART option becomes
enabled when used with the 1056, 1057, 1066, and 56 Analyzers and on 6081P wireless transmitter. The pH-loop capabilities include auto-recognition of the SMART sensor, automatic upload
of calibration data and associated time stamp, historical recording of pH diagnostics (slope,
offset, reference impedance, glass impedance). This trending data allows technicians to predict
frequency of maintenance and estimate sensor life for a particular process condition. Additional
SMART features include factory calibration, resetting SMART sensor calibration data with user
menus, and manufacturing information.
The TUpH large area reference junction for minimum maintenance requirements: The reference
junction provides an electrical connection between the reference electrode and the sample, and
helps maintain a stable reference potential, regardless of the change in sample pH. The TUpH
reference electrode junction, the entire plastic tip surrounding the glass pH electrode, maintains
a steady reference signal even in the dirtiest of applications because it resists plugging (a common
cause of pH signal drift). This large reference junction area is made of micron sized reference
pathways used for ionic exchange so it resists plugging by large particles and will continue to send
a steady pH signal, even in the dirtiest of applications. The TUpH reference junction technology
has been field-proven for minimum maintenance requirements.
The TUpH helical reference pathway stops reference poisoning. Ions diffuse through the reference
pathways and a charge is passed to the reference element. The reference element must be
protected from contamination by poisoning ions such as sulfide, mercury, cyanide, and ammonia
or else the pH signal will drift. The TupH sensor's long internal helical reference pathway hinders
and slows down the rate of contaminants migrating to the reference element therefore providing
for a longer sensor life.
The entire line of TUpH model sensors now incorporate the new SILCORE™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
compromising the integrity of the pH measurement, sensor life is increased, especially at higher
temperatures where increased migrations occur. In addition, the SILCORE technology provides
added protection against sensor failure due to vibrations and shock by transferring damaging
energy away from the glass-to-metal seal.
The AccuGLASS™pH glass formulations exceed industry standards. The AccuGlass pH glass is a
result of many years of glass research resulting in a formulation which has been found to increase
the life of the sensor. Unlike other pH glasses presently on the market, this glass resists cracking
especially at higher temperatures and reduces sodium ion error commonly found in high pH
applications. Overall, the AccuGlass formulation enhances the sensor performance to measure pH
more accurately and have a longer sensor life than ever before.
A choice of flat or hemi glass pH glass electrodes is available to best meet various 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. In abrasive applications pitting from
silicates and other similar materials is minimized by the flat glass surface to provide longer sensor
life. Flat glass sensors are offered with a flat tip which is flush with the flat glass. The hemi bulb
glass is ideal for general purpose use and for those processes requiring greater accuracy over the
entire pH range. All hemi bulb sensors are offered with a standard shrouded tip which completely
surrounds the glass bulb for protection against solids. An optional slotted tip is also available and

e
allows the process to flow by the glass electrode for accurate and reliable pH measurement. Both
pH glass bulbs — the standard hemi or optional flat pH glass — are exceptional for increased resistance to high temperature and other effects of aging for longer life.
The TUpH reference junction and helical pathway combined with the AccuGLASS pH glass
performs exceptionally well in dirty, high solid applications and requires only minimum maintenance. This is the toughest pH sensor on the market and is still unmatched by all other pH
sensors. The constant increase in demand for the TUpH sensor proves it's success as the best
process industry pH sensor.
All TUpH sensor models have been 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. Various sensor materials,
depending on the sensor model, are available for a variety of different application needs.
SMART is the standard option. A preamplifier converts the high impedance pH signal into a
stable, noise-free signal and must be used with all pH sensors. An integral SMART preamplifier
stores calibration information and can be built into the sensor when ordering the SMART preamplifier option. Otherwise, a standard preamplifier can be used in a junction box or built into the
analyzer/transmitter. All integral preamplified SMART TupH Sensors are compatible with all Rosemount Analytical instruments.
The 396VP, 396PVP, and 396RVP are offered with a watertight VP sensor-to-cable connector
which eliminates rewiring and cable twisting when replacing sensors. The VP (Variopol) multiple
pin connector is an integral part of each sensor model and uses a mating VP cable. Once the cable
is installed and wired to the analyzer, sensors are easily replaced without replacing the cable,
without rewiring the analyzer (if the replacement sensor is the same as its predecessor). Also the
sensor can be disconnected from the cable before removal from the process which eliminates
cable twisting. VP8 cable assemblies work with all VP sensors. VP8 wiring is standard across all
pH sensor families. VP8 is required when used with SMART preamplified sensors.

The 396P and 396PVP sensors feature 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 Rosemount Analytical 54e, 56, 1056, 1057, 5081,
6081, 1066, and XMT instruments. In addition, the Model 396P sensor can be used with most
non-diagnostic Rosemount Analytical and other manufacturers’ instruments.
The 396P and 396PVP 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 396 and 396VP TUpH Sensors are housed in a stainless steel body with optional 1" threaded
connector suitable for insertion, submersion or flow through installation. The sensor includes a
general purpose glass pH electrode in the standard bulb or optional flat glass configuration. The
TUpH reference has a large area polypropylene junction with a gel filled reference electrolyte. The
396 and 396VP TUpH are available with an optional SMART integral preamplifier when choosing
the 396VP-55 option. Automatic temperature compensation is standard 3K Balco or Pt 100 RTD.
The 396R and 396RVP Sensors are designed for use with a 1-1/4 in. or 1-1/2 in. ball valve for hot
tap installation. The 396R and 396RVP are constructed of molded polypropylene housed in a titanium tube with EPDM seals to provide maximum chemical resistance. The sensors feature a titanium solution ground used for advanced sensor diagnostics when used with Rosemount
Analytical 54e, 56, 1056, 1057, 5081, 6081, 1066, and XMT instruments. These 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.

Inspect the outside of the carton for any damage. If damage is detected, contact the carrier
immediately. Inspect the hardware. Make sure all the items in the packing list are present and in
good condition. Notify the factory if any part is missing. If the sensor appears to be in satisfactory
condition, proceed to Section 2.2, Mounting.
NOTE: Save the original packing cartons and materials as most carriers require proof of damage
due to mishandling, etc. Also, if it is necessary to return the sensor to the factory, you must pack
the sensor in the same manner as it was received. Refer to Section 6.0 for return instructions. If
the sensor is to be stored, the vinyl boot should be filled with pH buffer solution and replaced on
sensor tip until ready to use.
CAUTION
Buffer solution, in the vinyl boot, may cause skin or eye irritation.
WARNING
Glass electrode must be wetted at all times (in storage and in line) to maximize sensor life.
2.2 Mounting
The sensor has been designed to be located in industrial process environments. Temperature and
pressure limitations must not be exceeded at any time. A caution label regarding this matter is
attached to the sensor. Please do not remove the label. See Figure 2-1.
CAUTION
Internal electrolyte fill solution may cause skin or eye irritation.
Mounting Guidelines:
1. Shake the sensor in a downward motion to remove any air bubbles that may be present inside
the tip of the pH glass.
2. Do not install the sensor on the horizontal. The sensor must be 10° off the horizontal to ensure
accuracy.
3. Do not install the sensor upside down.
4. Air bubbles may become trapped in the sensor end between the glass bulb and the sensor
body. This problem is most commonly encountered in areas of low flow or during calibration.
Shake the probe while immersed in solution to remove bubbles. This problem can be avoided
by ordering the sensor with the slotted tip (option -41).
In most cases, the pH sensor can simply be installed as shipped and readings with an accuracy of
± 0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the sensor
must be calibrated as a loop with its compatible analyzer or transmitter.
396P and 396PVP Sensors have a 1-inch MNPT process connection at the front of the sensor for
mounting into a 1-1/2 inch tee or the process pipes. See Figure 2-2 through Figure 2-7 for instal lation configurations.
NOTE: LARGE PIPE WRENCHES MUST NOT BE USED TO TIGHTEN THE SENSOR INTO A FLANGE OR
OTHER TYPE OF MOUNTING.
2.2.2 Submersion Mounting
396P and 396PVP Sensors also have a 1 inch MNPT process connection at the back of the sensor.
Utilizing a standard 1 inch union, the sensor may be mounted to a 1 inch SCH 80 CPVC or PVDF
standpipe. Tapered pipe threads in plastic tend to loosen after installation. It is therefore recom mended that Teflon1 tape be used on the threads and that the tightness of the connection be
checked frequently to assure that no loosening has occurred. To prevent rain water or condensation from running into the sensor, a weatherproof junction box is recommended. The sensor
cable must be run through a protective conduit for isolation from electrical interference or physical abuse from the process. The sensor should be installed within 80° of vertical, with the electrode facing down. The sensor’s cable should not be run with power or control wiring.
