Safety Information WARNING HIGH PRESSURE AND TEMPERATURE HAZARD Before removing the senosr, reduce the process pressure to 0 psig and cool down the process temperature. Failure to reduce the pressure and temperature may cause serious injury to personnel. CAUTION EQUIPMENT DAMAGE The wetted sensor materials may not be compatible with process composition and operating conditions.
Description and specifications Description The Rosemount 222 toroidal flow through conductivity sensor measures conductivity in highly conductive liquids up to 2 S/cm (2,000,000 μS/cm). A noninvasive flow through design allows for in-line installations without any obstruction to sample and makes these sensors ideal for use with viscous or fibrous liquids.
