ii
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.
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 AccuG
LASS 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.

SECTION 1.0
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 54e, 1055, 5081, 3081,
4081, 81 pH/ORP, and Xmt-P transmitters. In addition
Models 396P and 396PVP can be used with most nondiagnostic 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
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.

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
