Description and Specifications 3
The 396P and 396PVP sensors are available in two configurations: the standard shrouded tip, in
which the pH glass is completely recessed within the reference junction for abrasive or rough
applications, and the optional slotted tip with a partially exposed pH glass for viscous or low flow
a
pplications.
The 396P and 396PVP sensors feature a titanium solution ground, constructed in an annular
design around the pH/ORP electrode. The solution ground provides advanced sensor diagnostics
for preventative maintenance when used with Rosemount Analytical 54e, 56, 1056, 1057, 5081,
6081, 1066, and XMT instruments. In addition, the Model 396P sensor can be used with most
non-diagnostic Rosemount Analytical and other manufacturers’ instruments.
The 396P and 396PVP sensor is housed in a molded polypropylene body with EPDM seals,
making it virtually indestructible and chemically resistant. Complete encapsulation eliminates
leakage or high humidity problems traditionally found in other pH/ORP designs. The simplified
construction, designed with user convenience in mind, does not require electrolyte (KCl) replen-
ishment or any high maintenance troubleshooting procedures.
The 396 and 396VP TUpH Sensors are housed in a stainless steel body with optional 1" threaded
connector suitable for insertion, submersion or flow through installation. The sensor includes a
general purpose glass pH electrode in the standard bulb or optional flat glass configuration. The
TUpH reference has a large area polypropylene junction with a gel filled reference electrolyte. The
396 and 396VP TUpH are available with an optional SMART integral preamplifier when choosing
the 396VP-55 option. Automatic temperature compensation is standard 3K Balco or Pt 100 RTD.
The 396R and 396RVP Sensors are designed for use with a 1-1/4 in. or 1-1/2 in. ball valve for hot
tap installation. The 396R and 396RVP are constructed of molded polypropylene housed in a tita-
nium tube with EPDM seals to provide maximum chemical resistance. The sensors feature a tita-
nium solution ground used for advanced sensor diagnostics when used with Rosemount
Analytical 54e, 56, 1056, 1057, 5081, 6081, 1066, and XMT instruments. These advanced sensor
diagnostics provide preventative maintenance by notifying the operator of the need for replace-
ment and cleaning of an aged or fouled sensor, thus allowing continuous optimum performance.
The Rosemount Analytical 54e, 56, 1056, 1057, 1066, 5081, 6081, and XMT instruments offer
advanced sensor diagnostics to provide preventative maintenance by notifying the operator of
the need for replacement and cleaning of an aged or fouled sensor, thus allowing continuous
optimum performance. The 396R and 396RVP sensors also feature a slotted tip for protection
from breakage while allowing the process to flow by the glass electrode for accurate and reliable
pH measurement.
