The PRISM RT-110 series are online digital refractometers that measure the refractive index of a liquid sample. These sensors provide highly accurate concentration values for a wide variety of water and process related applications. They are stand-alone devices capable of self-sustained operation, live data logging and communication output. The Prism RT-110 series also offer fully integrated 4-20mA and RS-485 Modbus output signals for connectivity to any microprocessor-based controller, display, PLC, or DCS network. The Prism RT-110 series have built-in temperature-dependent equations to convert the measured sample temperature and refractive index to the percentage concentration of Mono Ethylene Glycol (MEG), Mono Propylene Glycol (MPG) and Sugar Content (Brix). Two installation design versions of the RT-110 series are available, including RT-110 for bypass flow installation and RT-110L for tank wall installation.
The PRISM RT-110 RT-110 is a very robust sensor and capable of operating in contaminated fluid samples. It is important, however, to note that users should take all precautions to prevent and filter suspended solids from the sample stream prior to the sensor to avoid tenacious deposit build-up on the sensor eye. In highly fouled applications, Pyxis recommends users conduct sensor eye cleaning on a regular basis. Pyxis Lab offers the Ultrasonic RT-Series Cleaning Module Kit (P/N 56208) for installation into the Tri-Clamp Flow Cell Assembly as an optional accessory allowing for automated online cleaning of the RT-110 refractive index sensor.
Data Center & CDU Cooling Applications
The RT-110 Series provides continuous, real-time refractive index and glycol concentration monitoring for CDU cooling systems using PG25 coolant, helping maintain proper freeze protection, heat transfer efficiency, and uptime in mission-critical data center environments.
