DANGER
Hazardous Area InstallationN
This sensor is not Intrinsically Safe. or Explosion Proof. Installations near flammable liquids or in
hazardous area locations must be carefully evaluated by qualified on site safety personnel.
To secure and maintain an intrinsically safe installation, an appropriate transmitter/safety
barrier/sensor combi nation must be used. The installation system must be in accordance with the
governing approval agency (FM, CSA or BASEEFA/CENELEC) hazardous area classification requirements. Consult your transmitter instruc tion manual for details.
Proper installation, operation and servicing of this sensor in a Hazardous Area Instal lation is entirely
the responsibility of the user.
CAUTION
Sensor/Process Application Compatibility
The wetted sensor materials may not be compatible with process composition and operating
conditions. Application compatibility is entirely the responsibility of the user.

Section 1: Description and Specifications
1.1TUpH 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.
1.1.1Rosemount 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.
1.1.2Rosemount 397 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.
1.1.2Rosemount 398 and 398VP Sensor Features and Applications
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).
