DESCRIPTION AND SPECIFICATIONS

1.1 FEATURES AND APPLICATIONS

The Model 396R and 396RVP Sensors are specifically designed for improved life in harsh, dirty applications where a separate sample stream is difficult to provide and greater insertion depths are required. Model 396R is designed for use with a 1-1/4 in. or 1-1/2 in. ball valve for hot tap installa- tion. The Model 396R is constructed of molded polypropylene housed in a titanium tube with EPDM seals to provide maxi- mum chemical resistance2,3.

Model 396R also features a titanium solution ground for advanced sensor diagnostics when used with the Models 1055, Xmt-P, 54e, 81, 3081, or 5081 pH/ORP Analyzer/ Transmitter. Advanced sensor diagnostics provide preventa- tive maintenance by notifying the operator for replacement and cleaning of an aged or fouled sensor for continuous optimum performance.

The sensor also features a shrouded tip for protection from breakage while allowing process to flow by the glass elec- trode for accurate and reliable pH measurement.

The Model 396R is available without an integral preamplifier only and 15 ft or 9.5 in. of integral high quality 9 conductor cable. The preamplifier must be housed in a remote location or in a J-Box kit for attachment at the rear, cable end of the sensor (order separately) or integral to the Analyzer/

Transmitter. The Model 396R is compatible with all Rosemount Analytical and various other manufacturers instruments.

The entire line of TUpH model sensors now incorporate the new SILCORE1 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 compro- mising the integrity of the pH measurement, sensor life is increased, especially at higher temperatures where increased migrations occur. In addition, the SILCORE tech- nology provides added protection against sensor failure due to vibrations and shock by transferring damaging energy away from the glass-to-metal seal.

Model 396RVP: Rosemount Analytical has recently released Model 396RVP. This model has identical performance and physical specifications to the Model 396R (see Section 1.2) with the following exception: the Model 396RVP has a Variopol (VP) connector on the back end of the sensor in place of a cable.

All TUpH sensors are designed with a large area reference junction, helical reference pathway, and an AccuGlass pH

glass bulb. This sensor technology ensures superior performance while only requiring minimal maintenance.
