1.1
1.1.1
TUpH Features and Applications
The low maintenance and disposable Rosemount 396, 396VP, 397, 398, and 398VP TUpH sensors
offer long life and high performance in measuring pH or ORP in aqueous solutions in pipelines, open
tanks, or ponds.
These TUpH sensors feature a large area reference junction for maximum resistance to process
coatings, generally found in dirty, high solid applications. In addition, the secondary helical reference
pathway 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.
Rosemount 396 and 396VP Sensor Features and Applications
Rosemount 396/396VP sensors are constructed of
polypropylene and stainless steel and are completely
sealed by EP (ethylene propylene) to eliminate process
intrusion.
Sesnors are specially 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.
1.1.2
Rosemount 397 Sensor Features and Applications
1.1.2
Rosemount 398 and 398VP Sensor Features and Applications
The Rosemount 397 is housed in a highly chemical resistant
polypropylene body and completely sealed with EP to
eliminate process intrusion. The Rosemount 397 body is
specifically designed for use with the Quik-Loc Kit which
consists of an adapter and coupler. The PEEK (poly
etheretherke tone) adapter enables the Rosemount 397
sensor to fit into a 1 in. MNPT Dixon coupler for quick and
easy removal without sensor cable twisting. The 316 stain
less steel DIxon coupler is sealed with EP an features locking
arms. 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.
The chemical-resistant construction of Tefzel, titanium, and the TUpH reference junction make the
Rosemount 398 and 398VP the ideal sensors for measuring pH in harsh process liquids. Use these
sensors 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.
Rosemount 398 and 398VP sensors 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).

Unpacking and Inspection
Inspect the outside 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

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.
Flow Through and Insertion Mounting for Rosemount 396, 396VP, 398,
and 398VP Sensors.
These 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 instal lation configurations.
Submersion Mounting for Rosemount 396, 396VP, 398, and 398VP
Sensors.
These 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 recom mended
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.

Quik-Loc Mounting for Rosemount 397
The Quik- Loc mounting is used with the Rosemount 397 sensor only.
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
Rosemount 397 sensor is not recommended for use with hazardous, corrosive, or strong oxidizing chemi
cals due to a risk of spray or bodily injury.
WARNING
It is recommended that a thermometer, drain valve to relieve pressure and pressure gauge be inserted
near the Quik-Loc assembly (see Figure 2-5).
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 connection 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 wrap
ping 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 Rosemount 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™ spring arm has been provided on one arm so that the arm cannot
be opened until the spring is released.
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.
WARNING
It is the responsibility of each company 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
Rosemount 397 sensor in Section 1.2.

Calibration Using Buffer Solution or Grab Sample
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.
The pH sensor-transmitter loop may be calibrated by submersing the sensor in a buffer solution
(standard solutions of known pH values) or in a process grab sample whose pH value maybe
checked by a calibrated laboratory or portable pH meter.
Please refer to the transmitter instruction manual for proper calibration procedures.

Section 4: Maintenance
Maintenance
March 2017
Rosemount 396, 396VP, 397, 398, and 398VP sensors are disposable type sensors and therefore
require minimum maintenance. Every 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
SENSOR IS IN PRESSURIZED SYSTEM! May cause spray and bodily injury. Before removing 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 transmitter instruction manual for proper test
procedures. If it is determined that the sensor has failed, it should be discarded and replaced.
4.1
Electrode Cleaning
If the electrode is coated or dirty, clean as follows:
1.
Remove the sensor from process.
3.
Wash the glass bulb in a strong detergent solution and rinse it in clean water. If this does
not clean the glass bulb, go to Step 4.
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.)
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.
NOTICE
Erroneous pH results may occur immediately after acid soak, due to reference junction potential buildup. Replace the sensor if cleaning does not restore sensor operation.

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 Pt-100 will read 110 ohms. Resistance
varies with temperature for a 3K and Pt-100 element and can be determined according to Table 42 or the following formula:
RT=R0 [l+R1 (T-20)]
Where RT = Resistance
T = Temperature in °C
