Rosemount™ 228 Toroidal Conductivity Sensor

The Rosemount 228 Toroidal Conductivity Sensor measures conductivity in solutions up to 2 S/cm (2,000,000 µS/cm).

The Rosemount 228 Toroidal Conductivity Sensor reliably measures conductivity in highly conductive electrolyte solutions up to 2 S/cm (2,000,000 µS/cm). These conductivity sensors work in dirty and corrosive applications where metal electrode sensors would otherwise fail. A robust sensor design makes the Rosemount 228 conductivity sensor ideal for measuring concentrations of acid, base and salt solutions.

Key Features

  • Meet challenging application requirements with a selection of chemical resistant body options including PEEK and Tefzel
  • High vibration tolerance with reinforced internal metal frame design
  • High temperature option for process temperatures up to 200 °C (392 °F) and suitable for use under high pressure up to 295 psig (2135 kPa [abs])
  • Suitable for insertion and submersion type applications
  • Versatile mounting options featuring either a 3/4" MNPT or 5/8" 11 UNC process connection
  • Eliminate the need to shut down your process when removing conductivity sensors from piping and tanks by using an optional retraction assembly kit
