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. Overview A TUpH® sensor design ■ Coating and fouling resistant with large surface area TUpH reference junction. ■ Titanium and Tefzel sensor construction for superior chemical resistance to aggressive chemicals, such as chlorine dioxide in pulp bleaching towers and most organic solvents. ■ Selectable O-ring options of either EPDM, Viton® , or Kalrez® . ■ Optional flat pH glass electrode for abrasive and coating applications. ■ Operates in process pressures up to 250 psig. Versatile installation options ■ Suitable for insertion/submersion type installations (Rosemount 398/398VP). ■ Retractable design allows sensors to be removed for calibration and maintenance without process shutdown (Rosemount 398R/398RVP). ■ Variopol (VP8) cable connection option, for quick cable-tosensor 2 /Rosemount Ordering information Rosemount 398/398VP sensors are housed in a titanium tube and constructed with a Tefzel reference junction. Sensors can be used with a 1-in. MNPT process connector (sold separately). Rosemount 398 sensors come standard with 15-ft. (4.6 m) of integral cable. Rosemount 398VP sensors are used with quick disconnect VP8 interconnecting cables (sold separately).
