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 junction1 for maximum resistance to process coatings, generally found in dirty, high solid applications. In addition, the second- ary helical reference pathway2 serves as added pro- tection from poisoning ions. The simplified construc- tion, designed with user convenience in mind, does not require electrolyte replenishment or any compo- nent 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 mat- ing VP connector must be used. All models are com- patible with all Rosemount Analytical and most manu- facturers instruments.

The entire line of TUpH model sensors now incor- porate 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, espe- cially at higher temperatures where increased migra- tions occur. In addition, the SILCORE4 technology pro- vides added protection against sensor failure due to vibrations and shock by transferring damaging energy away from the glass-to-metal seal.

1.1.1Model 396 and 396VP TUpH Features and Applications.

The Models 396 and 396VP TUpH sensors are construct- ed of polypropylene and stain- less steel and is completely sealed by EP (ethylene propy- lene) 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 process connection for insertion, submersion, or flow through applications.

1.1.2Model 397 TUpH and Quik-Loc3Features and Applications. The Model 397 is housed in a highly chemical resistant polypropylene body and completely sealed with EP to eliminate process intru- sion. 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 Dixon coupler for quick and easy removal without sensor cable twisting. The 316 stainless steel DIxon coupler is sealed with EP and features locking arms. The Quik-Loc Kit is not recom- mended for use in processes with hazardous, corro- sive, or strong oxidizing chemicals due to a risk of spray and bodily hazards.

1.1.3Model 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 ACCUGLASS4 pH bulb allows for ultimate chemical resistance and makes Models 398 and 398VP the perfect choice for measuring pH in harsh, demanding processes.
