Rosemount Part no. 389VP-12-54
Rosemount 389/389VP sensors are suitable for use in a wide variety of applications. Reliably measure pH or
oxidation/reduction potential of aqueous solutions in pipelines, open tanks, and ponds. These sensors are
ideal for use in process solutions containing poisoning ions.
Reliability meets robustness.
■ A triple junction reference prolongs sensor life and protects against poisoning ions, such as ammonia, chlorine, cyanides, and sulfides.
■ Enhanced performance and increased life with cracking resistant glass.
■ Available with a glass electrode option for high pH applications.
■ Superior chemical resistance provided by a rugged Tefzel® body with Viton® O-rings.
Ease of installation.
■ The molded sensor body features 1-in. (25,4 mm) MNPT front and rear facing process connections for insertion, submersion,
and flow-through applications.
■ Variopol (VP8) cable connection option, for quick cable-to-sensor release, eliminates cable twisting (Rosemount™ 389VP).
Maintenance made simple.
■ Automatic recognition of pH sensors by Rosemount transmitters: 56, 1056, 1057, and 1066 with integral SMART preamplifier.
■ pH calibration data is stored, which allows sensors to be calibrated in advance for “plug and play” installations in the field.
