Rosemount pH ORP Sensor
Rosemount pH ORP Sensor UpH Sensor 398 398VP
A TUpH Sensor Design
Coating and fouling resistant with large surface area TUpH reference junction.
First, titanium and Tefzel sensor construction for superior chemical resistance to aggressive chemicals such as chlorine dioxide in pulp bleaching towers and most organic solvents.
Second, selectable O-ring options of either EPDM, Viton, or Kalrez.
Third, optional flat pH glass electrode for abrasive and coating applications.
Last, operates in process pressures up to 250 psig.
Versatile Installation Options
Suitable for insertion/submersion type installations (Rosemount 398/398VP).
And retractable design allows sensors to remove for calibration and maintenance without process shutdown (Rosemount 398R/398RVP).
Besides that, compatible for use with a 1-1/2 in. or 1-1/4 in. ball valve (Rosemount 398R/398RVP).
Then, variopol (VP8) cable connection option, for quick cable-to-sensor release, eliminates cable twisting.
Rosemount 398/398VP sensors housed in a titanium tube and constructed with a Tefzel reference junction. What’s more, sensors can be used with a 1 inch MNPT process connector (sold separately). Rosemount 398 sensors come standard with 15 ft. of integral cable.
However, rosemount 398VP sensors used with quick disconnect VP8 interconnecting cables (sold separately)
TUpH Sensors for Your Tough pH/ORP Applications
Rosemount 398/398VP/398R/398RVP TUpH pH sensors are robust sensors design to meet a number of difficult application requirements. Becuase sensors feature a variety of options suited to meet a number of installation requirements and are ideal for use in dirty,
abrasive, coating, and high solid applications containing chlorine dioxide.
