Section 1: Description and Specifications
1.1 Features 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

large area reference junction, helical reference pathway, and an AccuGlass pH glass bulb. This sensor technology
nsures superior performance while only requiring minimal maintenance.
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.

396P + 396PVP Sensors Instruction Manual Section 1: Description and Specifications
LIQ_MAN_396P_396PVP August 2013
The 396P and 396PVP sensors are 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
pplications.
a
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.
The Rosemount Analytical 54e, 56, 1056, 1057, 1066, 5081, 6081, and XMT instruments offer

Section 2: Installation
2.1 Unpacking and Inspection
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.

August 2013 LIQ_MAN_396P_396PVP
2.2.1 Flow Through and Insertion Mounting
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.

Section 3: Wiring
3.1 General
Figures in this section provide the guidelines for wiring the 396P-01 sensor to various
Analyzer/Transmitter instruments.
To determine which wiring guideline to use, locate the model number of the sensor to be installed.
1. If the cable needs to be extended, use a high quality eleven conductor double shielded instrument cable available from Rosemount Analytical. Refer to Table 3-1 for the appropriate junction box to use and the corresponding wiring details.
NOTE: If the cable is too long, loop up the excess cable. If the cable has to be shortened, cut and
terminate each conductor neatly and make sure that the overall (outermost) drain wire is not
shorted out with either of the two inner drain wires (shields).
2. Signal cable should be run in a dedicated conduit (preferably an earth grounded metallic
conduit) and should be kept away from AC power lines. For your convenience, a wire nut kit is
furnished (in a plastic bag wrapped around the cable).
NOTE: For maximum EMI/RFI protection when wiring from the sensor to the junction box, the
outer braid of the sensor should be connected to the outer braided shield of the extension cable.
The outer braid of the extension cable to the instrument must be terminated at earth ground or
by using an appropriate metal cable gland fitting that provides a secure connection to the instrument cable.
Wiring
The 396P and 396PVP has an optional built-in preamplifier and is offered with a shielded cable.
The cable should be handled carefully and kept dry and free of corrosive chemicals at all times.
Extreme care should be used to prevent it from being twisted, damaged or scraped by rough,
sharp edges or surfaces.
DANGER
DO NOT CONNECT SENSOR CABLE TO POWER LINES. SERIOUS INJURY MAY RESULT.
NOTE: Remove electrical tape or shrink sleeve from gray reference wire before connecting wire

396P + 396PVP Sensors Instruction Manual Section 4: Start-Up & Calibration
LIQ_MAN_396P_396PVP August 2013
Section 4: Start-Up and Calibration
4.1 396P and 396PVP pH Sensors
4.1.1 Sensor preparation
Shake down the sensor to remove any air bubbles that may be present at the tip of the pH glass
bulb. 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.
4.1.2 pH Calibration
After a temporary connection is established between the sensor and the instrument, a buffer
calibration may be performed. Consult appropriate pH/ORP analyzer or transmitter instruction
manual for specific calibration and standardization procedures, or see below for recommended
two-point buffer calibration procedure.
Recommended two-point buffer calibration procedure:
Select two stable buffer solutions, preferably pH 4.0 and 10.0 (pH buffers other than pH 4.0 and
pH 10.0 can be used as long as the pH values are at least two pH units apart).
NOTE: A pH 7.0 buffer solution reads a mV value of approximately zero, and pH buffers read
approximately 59.1 mV for each pH unit above or below pH 7.0. Check the pH buffer manufacturer specifications for millivolt values at various temperatures since it may affect the actual value
of the buffer solution mV/pH value.
1. Immerse sensor in the first buffer solution. Allow sensor to adjust to the buffer temperature
(to avoid errors due to temperature differences between the buffer solution and sensor
temperature) and wait for reading to stabilize. Value of buffer can now be acknowledged by
analyzer/transmitter.
2. Once the first buffer has been acknowledged by the analyzer/transmitter, rinse the buffer solution off of the sensor with distilled or deionized water.
3. Repeat steps 1 and 2 using the second buffer solution.
4. Once the analyzer/transmitter has acknowledged both buffer solutions, a sensor slope
(mV/pH) is established (the slope value can be found within the analyzer/ transmitter).
5. The slope value should read about 59.1 mV/pH for a new sensor and will decrease over time to
approximately 47-49 mV/pH. Once the slope reads below the 47-49 mV/pH range, a new
sensor should be installed to maintain accurate readings.
Recommended pH Sensor Standardization:
For maximum accuracy, the sensor can be standardized online or with a process grab sample
after a buffer calibration has been performed and the sensor has been conditioned to the
process. Standardization accounts for the sensor junction potential and other interferences.
Standardization will not change the sensor’s slope but will simply adjust the analyzer’s reading to
match that of the known process pH.
1. While obtaining a process solution sample (it is recommended that the sample is taken close
to the sensor), record the pH value that is shown on the analyzer/transmitter display.
Start-Up and Calibration 35
Section 4: Start-Up & Calibration 396P + 396PVP Sensors Instruction Manual
August 2013 LIQ_MAN_396P_396PVP
2. Measure and record the pH of the process solution sample with another temperature compensated, calibrated pH instrument. For best results, standardization should be performed at the
process temperature.
3. Adjust the analyzer/transmitter value to the standardized value.
4.2 396P and 396PVP ORP Sensors
4.2.1 Sensor preparation
Most industrial applications have a number of ORP reactions occurring in sequence or simultaneously. There can be several components that are oxidized or reduced by the reagents that are
used. Theoretically, the ORP potential is absolute because it is the result of the oxidation-reduction equilibrium. However, the actual measured potential is dependent on many factors,
including the condition of the surface of the ORP platinum electrode. Therefore, the sensor
should be allowed 1-2 hours to become “conditioned” to the stream when first set-up or after
being cleaned.
4.2.2 ORP Calibration
1. Make a temporary electrical connection between the sensor and the instrument.
2. Obtain an ORP standard solution, or a standard solution can also be made quite simply by
adding a few crystals of quinhydrone to either pH 4 or pH 7 buffer. Quinhydrone is only slightly
soluble therefore a few crystals will be required. (Refer to Section 4.3. for an alternate ORP
standard solution).
3. Immerse the sensor in the standard solution. Allow 1-2 minutes for the ORP sensor to stabilize.
4. Adjust the standardize control of the instrument to the solution value shown in Table 5-1
(below) or on the label of the standard solution. The resulting potentials, measured with a
clean platinum electrode and saturated KCl/AgCl reference electrode, should be within ±20
millivolts of the value. Solution temperature must be noted to ensure accurate interpretation
of results. The ORP value of saturated quinhydrone solution is not stable over long periods of
time. Therefore, these standards should be made up fresh each time they are used.
5. Remove the sensor from the buffer, rinse and install in the process.

Section 5: Maintenance
5.1 General Information
The 396P and 396PVP Sensors require minimum maintenance. The sensor should be kept clean
and free of debris and sediment at all times. The frequency of cleaning by wiping or brushing with
a soft cloth or brush is determined by the nature of the solution being measured. The sensor
should be removed from the process periodically and checked in buffer solutions.
DANGER
BEFORE REMOVING THE SENSOR, be absolutely certain that the process pressure is reduced to 0 psig
and the process temperature is lowered to a safe level!
If the sensor will not calibrate, refer to your analyzer/ transmitter instruction manual for proper
test procedures. If it is determined that the sensor has failed, it
5.2 Automatic Temperature Compensator
The temperature compensator element is temp erature sensitive and can be checked with an
ohmmeter. Resistance increases with temperature.
The 3K element will read 3000 ohms ±1% at 25°C (77°F) and a Pt100 will read 110 ohms. Resistance varies with temperature for a 3K and Pt100 element and can be determined according to
Table 6-2 or the following formula:
RT=RO[l+R1(T-20)]
Where RT= Resistance
T = Temperature in °C
Refer to Table 6-1 for ROand R1values
5.3 396P & 396PVP pH Sensors
5.3.1 Electrode Cleaning
If the electrode is coated or dirty, clean as follows:
1. Remove the sensor from process.
2. Wipe the glass bulb with a soft, clean, lint free cloth or tissue. If this does not remove the dirt
or coating, go to Step 3. (Detergents clean oil and grease; acids remove scale.)
3. Wash the glass bulb in a mild detergent solution and rinse it in clean water. If this does not
clean the glass bulb, go to Step 4.
CAUTION
The solution used during the following check is an acid and should be handled with care. Follow the
directions of the acid manufacturer. Wear the proper protective equipment. Do not let the solution
come in contact with skin or clothing. If contact with skin is made, immediately rinse with clean water.
4. Wash the glass bulb in a dilute 5% hydro chloric acid solution and rinse with clean water.
Soaking the sensor overnight in the acid solution can improve cleaning action.

5.4.1 Platinum Electrode Check
The platinum electrode may be checked as follows: There are two types of standard solutions
which may be used to check the ORP electrode/transmitter system.
Type 1: One type of commonly used ORP standard solution is the saturated quinhydrone solution. Refer to Section 5.2.
CAUTION
The solution used during the following check is an acid and should be handled with care. Follow the
directions of the acid manufacturer. Wear the proper protective equipment. If contact with skin of
clothing is made, immediately rinse with plenty of clean water.
Type 2: A second ORP standard solution is the Ferric-Ferrous Ammonium Sulfate Solution (PN
R508-16OZ), and it can be ordered as a spare part; otherwise, it can be prepared from the
following recipe: Dissolve 39.2 grams of reagent grade ferrous ammonium sulfate, Fe(NH4)2
(SO4)2 • 6H2O and 48.2 grams of reagent grade ferric ammonium sulfate, FeNH4(SO4)2 •
12H2O, in approximately 700 milliliters of water (distilled water is preferred, but tap water is
acceptable). Slowly and carefully add 56.2 milliliters of concentrated sulfuric acid. Add sufficient
water to bring the total solution volume up to 1000 ml. This standard ORP solution, although not
as simple to prepare as the quinhydrone recipe, is much more stable, and will maintain its millivolt value for approximately one year when stored in glass containers. This solution (ferric/ferrous
38 Maintenance

mmonium sulfate) will produce a nominal ORP of 476 +20 mV at 25°C when used with a satu-
a
rated KCl/AgCl reference electrode and platinum measuring electrode. Some tolerance in mV
values is to be expected due to the rather large liquid reference junction potentials which can
arise when measuring this strongly acidic and concentrated solution. However, if the measuring
electrodes are kept clean and in good operating condition, consistently repeatable calibrations
an be carried out using this standard solution.
c
5.4.2 Cleaning Platinum Electrode
The electrode can be restored to normal operation by simply cleaning the platinum electrode
with baking soda. Polish it by rubbing it with a damp paper towel and baking soda until a bright,
shiny appearance is attained.
