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 sensors feature a patented, large area reference junction1for maximum resistance to process coatings,
generally found in dirty, high solid applications. In
addition, the secondary helical reference pathway
2
serves as added protection from poisoning ions. The
simplified construction, designed with user convenience in mind, does not require electrolyte replenishment or any component replacement. All models feature a large glass bulb for increased resistance to the
effects of aging for longer life. All models are available only without an integral preamplifier. The preamplifier 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 constructed of polypropylene and
stainless steel and is completely sealed by EP (ethylene propylene) to eliminate
process intrusion. It is specifically designed for improved life in harsh, dirty applications such as lime slurry waste treatment and paper
machine headbox and pigment/dye applications
where large quantities of suspended solids are present. Installation is easily achieved through a wide variety of mounting configurations. The Model 396 features an optional front or rear 1 in. MNPT pr ocess connection 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®4Kamloc®4coupler for quick and easy
removal without sensor cable twisting. The 316 stainless steel Twin-Kam®Kamloc®coupler is sealed with
EP and features “vibration resistant”5arms. The QuikLoc 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 construction of Tefzel, titanium,
and the patented TUpH reference 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 materials to provide superior chemical resistance. The sensors 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 quality materials with the TUpH reference technology and
A
CCUGLASS pH bulb allows for ultimate chemical
resistance and makes Models 398 and 398VP the perfect choice for measuring pH in harsh, demanding
processes.

2.2.1 Flow Thr ough 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 connector 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 condensation 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 control wiring.
2.2.3 Quik-Loc Mounting for Model 397. The QuikLoc mounting is used with the Model 397 TUpH sensor only.
SAFETY WARNING
It is recommended that a thermometer, 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 operator 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, corrosive, or strong oxidizing chemicals due to
a risk of spray or bodily injury.

INSTALLATION
2.1 UNPACKING AND INSPECTION. Inspect the out-
side of the carton for any damage. If damage is detected, contact the carrier immediately. Inspect the instrument and 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 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 sensor 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 instructions. 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 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.
