Rosemount 228-02-20-56-61-CC Toroidal Conductivity Sensor

The Rosemount 228-02-20-56-61-CC is a toroidal (electrodeless) conductivity sensor from Emerson's Rosemount Analytical liquid-analysis line, built for submersion or insertion measurement in dirty, corrosive, or highly conductive process liquids where contacting-electrode sensors would foul or corrode. It measures conductivity up to 2 S/cm (2,000,000 µS/cm) with a nominal cell constant of K = 2.7/cm, and carries an integral Pt100 RTD for automatic temperature compensation. This glass-filled PEEK, standard-temperature body is rated to 120°C (248°F) and 295 psig (2135 kPa abs), suiting it to applications such as CIP/SIP monitoring, wastewater treatment, and chemical concentration control when paired with a Rosemount conductivity analyzer such as the 1056, 1066, or 5081-C.

In the Rosemount 228 model code, 02 designates the glass-filled PEEK, standard-temperature sensor body; 20 specifies a 5/8-11 UNC process connection with EPDM gasket standard; 56 indicates shielded cable for improved EMI/RFI immunity; and 61 denotes a 20 ft (6.1 m) integral cable length. The -CC suffix adds a Certificate of Conformance to the shipment.
