The Rosemount Analytical TUpH Model 396 / 396VP pH/ORP Sensors are specifically designed for improved life in harsh, dirty, and abrasive applications such as lime slurry waste treatment, paper machine headbox and pigment/dye applications, where large quantities of suspended solids are present.

The Model 396 is available with custom glass electrodes, optional flat or standard hemi glass pH bulb, to best meet your application needs. Flat glass is advantageous in abrasive or coating applications that etch or build up on glass respectively. In coating applications, such as slurries, the flat surface allows the process flow to act as a scrubbing agent to reduce coating and maintenance whereas in abrasive applications pitting from silicates and other similar materials is minimized by the flat surface to provide longer life. The hemi bulb is ideal for general purpose use and for those processes requiring greater accuracy over the entire pH range.

The sensor is housed in a stainless steel body with EPDM seals. The simplified construction, designed with user convenience in mind, does not require electrolyte replenishment or any component replace-ment. The Model 396 also features a large glass bulb for increased resistance to high temperature and other effects of aging for longer life.

The Model 396 is not available with an integral preamplifier. The preamplifier must be in a remote location or integral to the analyzer/transmitter. Therefore, the Model 396 is compatible with all Rosemount Analytical and other manufacturers' instruments.

The Model 396VP insertion/submersion sensor features a gel-filled electrolyte solution with the large area, coating resistant TUpH reference junction in polypropylene and a standard hemi or optional flat glass bulb. It is housed in a metal sensor tube, 316 SST for Model 396VP, and can be mounted in insertion, submersion, or flow through installations using a 1 in. MNPT threaded process connector (ordered separately). It is offered with the watertight Variopol sensor-to-cable connector and use the mating connector cable(ordered separately). VP8 cable assembly works with both VP8 and VP6 sensor connector. Also available is a choice of temperature element 3 K Balco or Pt 100 RTD. Model 396VP is SMART enabled. Option (-70) is the standard option. A remote preamplifier found in the analyzer/transmitter or in a junction box (ordered separately) must be used with 398VP sensors for reliable signal transmission. VP8 cable is required for SMART communication.
