Overview
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.
Benefits
* 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 optionalretraction assembly kit
