Pyxis PRISM RT-110 Series Compact Inline Refractometer

The Pyxis PRISM RT-110 series is a compact inline digital refractometer that measures the refractive index of a liquid (1.31700-1.5100, ±0.0001 accuracy) and converts it to 0.00-85.00 %BRIX, 0.00-100.00 %MEG (mono-ethylene glycol) or 0.00-100.00 %MPG (mono-propylene glycol). The body is 316L stainless steel with a sapphire optical surface (IP-67, ≤0.98 MPa), and outputs are 4-20 mA and RS-485 Modbus. Mikron Proses (Üsküdar, Istanbul) provides application consulting on choosing between the by-pass (RT-110) and tank (RT-110L) versions.

The series is built on the RT-100 platform and is a stand-alone device that can log live data and provide communication output. For other refractometers from the same maker, see the RT-200 high-temperature refractometer and the RT-50 cutting fluid refractometer.

Two mounting types: RT-110 and RT-110L

The series offers the same measuring core in two mounting designs. The RT-110 (P/N 59207) is installed in a by-pass sample line with a 3/4-inch NPT flanged 316L stainless steel Tri-Clamp flow cell assembly and works at sample temperatures of -20 to 70 °C. The RT-110L (P/N 57682) is installed directly on the wall of a tank or reservoir with a 2.5-inch stainless steel sanitary clamp coupling; its sample temperature range is slightly narrower, -20 to 65 °C. Both models measure refractive index with 0.00001 resolution and ±0.0001 accuracy, and %BRIX and glycol with 0.01 resolution and ±0.1 accuracy, over a measurement temperature range of -20 to 80 °C.

Data center coolant monitoring

The datasheet states that the RT-110 is designed to integrate into data center coolant monitoring systems.

Outputs, calibration and body

The RT-110 series connects to any microprocessor-based controller, display, PLC or DCS network through its integrated 4-20 mA and RS-485 Modbus outputs. The RT-110 series has no built-in display or built-in Bluetooth; wireless access, diagnostics and calibration need the optional MA-CR Bluetooth adapter, which is purchased separately. When connected, the uPyxis app offers air calibration of the refractive index, offset calibration of the liquid concentration, a return to factory settings, history transfer (up to 56 days at 1 reading per minute) and live trend display of refractive index and temperature. Both models have a 316L stainless steel body and sapphire measuring surface, are IP-67, weigh 1 kg and measure φ64 × 133 mm; maximum sample pressure is 0.98 MPa, maximum flow is below about 51 L/min and the supply is 24 VDC (1.5 W). The manufacturer notes that suspended solids in contaminated samples can build up on the optical surface, so the sensor surface should be cleaned regularly, and the optional RT-series ultrasonic cleaning module can be used (for the RT-110L only).
