KxS process refractometer DCM-20 is intended for reliable liquid concentration and density measurements in wide range of chemical and industrial process applications. It is installed in the main processing line, bypass line or vessel either directly with industrial Flange or L-coupling process connection, or via flow cell or pipe section. The DCM-20 withstands corrosive and abrasive conditions, extreme temperatures and pressures, vibration, contamination, humidity, dust, and any combination of these factors. It is true stand-alone device with all measurement functions integrated in the sensor, thus eliminating the need of transmitter. Measurement output options include both analog and digital communication protocols. Two cable connection ports offer dual analog 4-20mA and Modbus TCP. For enhanced functionality, an optional HMI unit offers a local display and interface, ensuring user-friendly operation. In demanding process conditions, one mA-output can be dedicated to controlling the optical window wash, maintaining optimal performance and cleanliness.
