Product Description

Product Description

Rosemount™ 396 Series TUpH® pH/ORP Sensors
Robust Solutions for Demanding Industrial Applications
1. Product Line Overview
The Rosemount™ 396 series comprises a family of rugged pH and Oxidation-Reduction Potential (ORP) sensors engineered for reliability in harsh industrial environments. This product line includes six primary models:
396/396VP: Immersion/insertion sensors with stainless steel bodies .
396P/396PVP: Threaded-process sensors featuring 1-inch NPT connections for direct piping installation .
396R/396RVP: Retractable sensors with titanium housings (21-inch or 36-inch lengths) for maintenance without process shutdown 
All models integrate Emerson's patented TUpH® reference technology, specifically designed to minimize maintenance and maintain signal stability in coating, abrasive, high-solid, and chemically aggressive applications .

2. Core Technology: TUpH® Reference System
2.1. Anti-Clogging Design
Large-Area Polypropylene Junction: Unlike conventional ceramic junctions, the 396's expansive polymer junction resists clogging from slurries, fibers, or viscous media. This design sustains stable electrolyte flow even with 90% surface coating .
Helical Reference Pathway: A labyrinthine internal channel extends sensor life by delaying reference electrolyte poisoning. This geometry impedes contaminant ingress while maintaining stable liquid junction potential .
2.2. Electrode Innovations
GPHT Flat Glass Electrode (Optional): For abrasive applications (e.g., mining slurries, pulp & paper), the flat-surface electrode reduces mechanical wear and coating adhesion compared to hemispherical designs .
Titanium Grounding Electrode: Standard in 396R models, it eliminates stray currents in high-interference environments like power plants .
2.3. Gel Electrolyte System
Sealed Reference Cell: Polymer-gel electrolyte eliminates KCl replenishment, prevents drying, and extends service life up to 2× longer than liquid-filled sensors in high-temperature processes .
