construction, designed with user convenience in mind,
does not require electrolyte (KCl) replenishment or any
high maintenance troubleshooting procedures.

The Model 396P is offered with or without 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. A remote
preamplifier must be used with Model 396PVP.

Installation is easily achieved through the wide variety
of mounting configurations. The Models 396P and
396PVP feature 1 in.(MNPT) front and rear facing con­nections for insertion, submersion or flow through pH
and ORP applications.

Model 396PVP is offered with a watertight sensor-to­cable connector which eliminates re-wiring and cable
twisting when replacing sensors.The Variopol VP 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, and, if the
replacement sensor is the same as its predecessor,
without rewiring the analyzer. Also the cable can be
disconnected from the sensor before removal from
the process which eliminates cable twisting.

DESCRIPTION AND SPECIFICATIONS

1.1 FEATURES AND APPLICATIONS

The Rosemount Analytical Model 396P and 396PVP
Sensors measure the pH or the ORP of aqueous solu­tions in pipelines, open tanks, or ponds. It is designed
for harsh, dirty applications such as sourwater waste
treatment and scrubbers, where a high performance,
low maintenance, disposable sensor is required.

The combination electrode features a patented, large
area polypropylene reference junction for resistance to
process coatings, generally found in dirty, high solid
applications. The patented helical reference pathway
provides added resistance for poisoning applications.
In addition, it is available in two configurations:
glass/platinum electrode completely recessed within
the reference junction for added life in abrasive or
rough applications and the glass/platinum electrode
partially exposed for added life and accuracy in vis­cous and low flow applications.

Both Models feature a titanium solution ground con­structed in an annular design around the pH/ORP elec­trode. The solution ground provides glass and refer­ence sensor diagnostics for preventative maintenance
when used with the Model 54, 1055, 3081, 4081, and
81 pH/ORP transmitters. In addition Models 396P and
396PVP can be used with most non-diagnostic
Rosemount Analytical and other manufacturer’s instru­ments.

Each 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

MODEL 396P and 396PVP SECTION 2.0

INSTALLATION

SECTION 2.0

INSTALLATION

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.

2.2.1 Flow Through and Insertion Mounting.

Model 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 2-1 through Figure 2-7 for installation 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. Model 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 (see Figure 2­x). Tapered pipe threads in plastic tend to loosen after
installation. It is therefore recommended that Teflon

1

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 (see Figure 2-x). 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.

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 pr essur e
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.

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.

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.

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.

5.2 MODEL 396P and 396PVP ORP SENSORS

5.2.1 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.

5.2.2 ORP CALIBRATION

1. Make a temporar y electrical connection between the sensor and
the instrument.

2. Obtain an ORP standard solution (PN R508-160Z), 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 pr ocess.

MODEL 396P and 396PVP SECTION 5.0

START UP AND CALIBRATION

SECTION 5.0

START UP AND CALIBRATION

5.1 MODELS 396P and 396PVP pH SENSORS

5.1.1 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.

5.1.2 pH CALIBRATION. After a temporar y 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 tw

o-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 b uffers read appro ximately 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 aff ect 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 47­49 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 Standar

dization:

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.

MODEL 396P and 396PVP SECTION 6.0

MAINTENANCE

The Model 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.

WARNING

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
should be discarded and replaced.

6.1 AUTOMATIC TEMPERATURE
COMPENSATOR.

The temperature compensator element is temp­erature 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

6.2 MODEL 396P & 396PVP pH SENSORS

4.2.1 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.

SECTION 6.0

MAINTENANCE

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% hydrochloric
acid solution and rinse with clean water. Soaking
the sensor overnight in the acid solution can
improve cleaning action.

NOTE

Erroneous pH results may result immedi­ately after acid soak, due to reference
junction potential build-up.

Replace the sensor if cleaning does not
restore sensor operation.

4.3.1 Platinum Electrode Check. The platinum elec-

trode may be checked as follows: There are three
types of standard solutions which may be used to
check the ORP electrode/transmitter system.

Type 1: A prepared ORP standard solution
(PN R508-160Z)

Type 2: Another 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 3: A third ORP standard solution 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 ammoni­um sulfate) will produce a nominal ORP of 476 +20 mV
at 25°C when used with a saturated 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 can be car­ried out using this standard solution.

6.3.2 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.

DIAGNOSTICS AND TROUBLESHOOTING

7.1 MODEL 54/81/3081/4081 DIAGNOSTICS AND TROUBLESHOOTING

The Model 54 Analyzer and Models 81 and 3081 Transmitters automatically search for fault conditions that would
cause an error in the measured pH value, as does the Model 1054B pH/ORP Analyzer to a lesser degree. Refer to
the applicable Instruction Manual for a complete description of the analyzer’s fault conditions.

Table 7-1, below , lists the Model 54’s, 4081’s, 3081’s, and 81’s diagnostic messages that indicate a possible sen­sor problem. A more complete description of the problem and a suggested remedy corresponding to each mes­sage is also listed.
