SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
1.1 TUpH™ FEATURES AND APPLICATIONS.
Rosemount Analytical has achieved a new industry
standard for the life expectancy of pH sensors with
the TUpH Sensors. The low maintenance, disposable
Models 396, 396VP, 397, 398, and 398VP TUpH
Sensors offer long life and high performance in the
measurement of pH in aqueous solutions in
pipelines, open tanks, or ponds. These TUpH sen-
sors feature a patented, large area reference junc-
tion1for maximum resistance to process coatings,
generally found in dirty, high solid applications. In
addition, the secondary helical reference pathway2
serves as added protection from poisoning ions. The
simplified construction, designed with user conven-
ience in mind, does not require electrolyte replenish-
ment or any component replacement. All models fea-
ture a large glass bulb for increased resistance to the
effects of aging for longer life. All models are avail-
able only without an integral preamplifier. The pream-
plifier must be in a remote location or integral to the
analyzer/transmitter. Models with a “VP” after the
model number indicate the variopol connector is
used on the sensor in place of the cable. In this case,
a separate cable with a mating VP connector must be
used. All models are compatible with all Rosemount
Analytical and most manufacturers instruments.
1.1.1 Model 396 and 396VP TUpH
Features and Applications.
The Models 396 and 396VP
TUpH sensors are construct-
ed of polypropylene and
stainless steel and is com-
pletely sealed by EP (ethyl-
ene propylene) to eliminate
process intrusion. It is specifi-
cally designed for improved life in harsh, dirty appli-
cations such as lime slurry waste treatment and paper
machine headbox and pigment/dye applications
where large quantities of suspended solids are pres-
ent. Installation is easily achieved through a wide vari-
ety of mounting configurations. The Model 396 fea-
tures an optional front or rear 1 in. MNPT process con-
nection for insertion, submersion, or flow through
applications.
1.1.2 Model 397 TUpH and
Quik-Loc Features and
Applications. The Model 397 is
housed in a highly chemical
resistant polypropylene body
and completely sealed with EP
to eliminate process intrusion.
The Model 397 body is specifically designed for use
with the Quik-Loc Kit which consists of an adapter and
coupler. The PEEK (polyetheretherketone) adapter
enables the Model 397 sensor to fit into a 1 in. MNPT
Twin-Kam®4 Kamloc®4 coupler for quick and easy
removal without sensor cable twisting. The 316 stain-
less steel Twin-Kam®Kamloc®coupler is sealed with
EP and features “vibration resistant”5arms. The Quik-
Loc Kit is not recommended for use in processes with
hazardous, corrosive, or strong oxidizing chemicals
due to a risk of spray and bodily hazards.
1.1.3 Model 398 and 398VP TUpH
Features and Applications.
The chemical-resistant con-
struction of Tefzel, titanium,
and the patented TUpH refer-
ence junction make the
Models 398 and 398VP the
ideal sensors for measuring
pH in harsh process liquids.
Use Model 398 or 398VP to measure pH in sour water
strippers, in pulp bleaching towers that use chlorine
dioxide, and in process streams containing a variety
of organic solvents.
Models 398 and 398VP use the highest quality mate-
rials to provide superior chemical resistance. The sen-
sors are housed in a titanium tube and features an
optional 1 inch MNPT process connector for insertion,
submersion, or flow-through applications. The molded
Tefzel TUpH construction is offered with a choice of
seals (Viton, EPDM, or Kalrez). Combining high qual-
ity materials with the TUpH reference technology and
ACCUGLASS pH bulb allows for ultimate chemical
resistance and makes Models 398 and 398VP the per-
fect choice for measuring pH in harsh, demanding
processes.

2.2.1 FlowThrough and Insertion Mounting for Models
396, 396VP, 398, and 398VP. The Models 396, 396VP,
398, and 398VP Sensors can be used with a 1 inch
MNPT process connector at the front of the sensor for
mounting into a 1-1/2 inch tee or the process. See
Figure 2-1 for installation configurations.
2.2.2 Submersion Mounting for Models 396, 396VP,
398, and 398VP. The Models 396, 396VP, 398, and
398VP Sensors also have a 1 inch MNPT process con-
nector available for use on the back of the sensor.
Tapered pipe threads in plastic fittings tend to loosen
after installation. It is therefore recommended that Teflon
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 con-
densation from running into the sensor, a weatherproof
junction box is recommended (see Figure 2-4). 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 con-
trol wiring.
2.2.3 Quik-Loc Mounting for Model 397. The Quik-
Loc mounting is used with the Model 397 TUpH sen-
sor only.
SAFETY WARNING
It is recommended that a thermome-
ter, drain valve to relieve pressure
and pres-sure gauge be inserted
near the Quik-Loc assembly (see
Figure 2-5).
WARNING
Once the Quik-Loc unit is installed the oper-
ator should wait for the process to cool to a
safe temperature, use the pressure drain
valve to relieve all process pressure and
observe the pressure on the pressure
gauge for proper removal of the sensor
without spray or bodily injury. The Quik-Loc
kit used with the 397 TUpH sensor is not
recommended for use with hazardous, cor-
rosive, or strong oxidizing chemicals due to
a risk of spray or bodily injury.
MODEL 396/396VP/397/398/398VP SECTION 2.0
INSTALLATION
2.1 UNPACKING AND INSPECTION. Inspect the out-
side of the carton for any damage. If damage is detect-
ed, contact the carrier immediately. Inspect the instru-
ment and hardware. Make sure all the items in the pack-
ing list are present and in good condition. Notify the fac-
tory 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 instrument to the
factory, you must pack the instrument in the
same manner as it was received. Refer to
Section 6 for return instructions. If the sen-
sor is to be stored, the vinyl boot should be
filled with pH buffer solution and replaced
on sensor tip until ready to use.
WARNING
Glass electrode must be wetted at all times
(in storage and in line) to maximize sensor
life.
2.2 MOUNTING. Each sensor has been designed to
be located in industrial process environments.
Temperature and pressure limitations must not
be exceeded at any time. A caution or warning label
regarding this matter is attached to each sensor. For
insertion, transfer the label as shown on label instruc-
tions. See Figure 2-2. For submersion applications, first
note limits then remove and discard label.
NOTE
Before mounting the sensor, 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 sim-
ply 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 ana-
lyzer or transmitter.

MODEL 396/396VP/397/398/398VP SECTION 2.0
INSTALLATION
Wrap the pipe threads of the Twin-Kam Kamloc coupler
with Teflon tape before placing it into the process pipe.
The coupler can be connected to any 1 in. process con-
nection and must be mounted within 80° of vertical, with
the electrode facing down. Once the coupler is in place,
the adapter should be positioned onto the back end of the
sensor. (See Figure 2-5) Remove the parafilm wrapping
from the two 0-rings on the sensor, grease the o-rings with
the lube provided, and feed the sensor cable through the
adapter. Once the adapter is slipped over the sensor’s
back end, the retaining ring (which is included with every
397 sensor) should be installed on the black, grooved,
back end of the sensor body. The retaining ring secures
the sensor into the adapter. The adapter/sensor assembly
is now ready to be inserted into the coupler. With both
arms of the coupler in the released position, insert the
adapter/sensor assembly into the coupler.
NOTE
The adapter can not be inserted completely or
properly unless both arms are in the fully
released position (see Figure 2-5).
Once the adapter has been properly placed in the coupler,
both arms should be positioned in the locked position. A Sur-
Loc™ 1 spring arm has been provided on one arm so that the
“arm cannot be opened until the spring is released.”2
NOTE
The sensor may obstruct flow through smaller pipes.
Once the arms of the coupler have been locked in position,
use tamper-evident safety wire on the metal rings of the
Twin-Kam arms to prevent unauthorized and/or untrained
personnel from using the Quik-Loc unit.
SAFETY WARNING
It is the responsibility of each com-
pany using the Quik-Loc Kit/ 397
TUpH Sensor to train personnel of
the injury risks associated with
using a quick-release coupler that
is placed in a hot or pressurized
process.
The Quik-Loc unit should be used only within the pressure
and temperature limits stated for the Model 397 sensor in
Section 1.2.2.

Metal Process Connector PN 23166-xx
(xx = 00 for 316 SST and xx = 01 for tita-
nium) can be used for insertion or sub-
mersion mounting of Models 396VP or
398VP sensors in 1-inch fittings.
The metal process connector gives the sensor var-
ious insertions depths, depending on where the
user locates the compression fitting. Also the
threads can be switched to face the cable end of
the sensor for connection to submersion pipes.
