Pyxis RT-200 PRISM High Temperature Inline Refractometer
High-temperature inline digital refractometer measuring refractive index, %BRIX, and glycol concentration up to 120°C. Stainless steel Tri-Clamp body, IP67, built-in Bluetooth 5.0.
Pyxis RT-200 PRISM High Temperature Inline Refractometer
The Pyxis RT-200 PRISM is an inline digital refractometer that converts measured refractive index directly into concentration values for glycols, BRIX sugar content, and ALV fluids, with operation up to 120°C. It functions as a stand-alone unit with local display, onboard data logging, and 4-20mA plus RS-485 Modbus outputs for integration with a PLC, DCS, or third-party controller. Built-in Bluetooth 5.0 connects to the uPyxis mobile app for setup, diagnosis, and stored historical readings.
Description
The Pyxis RT-200 PRISM is an inline digital refractometer built for high-temperature process applications, measuring the refractive index of a liquid sample and converting it directly into accurate concentration values. Built-in temperature-compensated equations convert refractive index into percentage concentration for Mono-Ethylene Glycol (MEG), Mono-Propylene Glycol (MPG), Sugar Content (BRIX), and Advanced Low Viscosity Fluid (ALV), with operation up to 120°C — beyond what the standard RT-100 range is rated for, making it suited to sugar production and other high-temperature process monitoring.
It is a stand-alone device with a local display, push-button interface, and onboard data logging, and also outputs via 4-20mA and RS-485 Modbus for integration with a PLC, DCS, or third-party controller. Construction is 316L stainless steel with a sapphire measurement window, rated IP67, and it installs into a Tri-Clamp flow assembly with a 3/4″ NPT flange.
Built-in Bluetooth 5.0 connects to the uPyxis mobile app for setup, diagnosis, and up to 56 days of stored historical readings at 1-minute intervals. An optional Ultra-Sonic RT-Series Cleaning Module (P/N 56208) is available for automated online cleaning in fouled or contaminated fluid streams.
Why Use This
Rated for high-temperature process streams
Operates up to 120°C, covering sugar production and other hot applications outside the standard RT-100 range.
Multiple concentration outputs from one measurement
Built-in equations convert refractive index into MEG, MPG, BRIX, and ALV concentration values without separate instruments.
Remote setup and monitoring
Built-in Bluetooth 5.0 and the uPyxis app support configuration, diagnosis, and review of up to 56 days of stored readings.
Applications
- Sugar production process monitoring — high-temperature BRIX measurement up to 120°C
- Glycol concentration monitoring — measures MEG and MPG concentration in process streams
- High-temperature process fluid monitoring — suited to hot process streams beyond standard refractometer ratings
- PLC/DCS-integrated concentration control — 4-20mA and RS-485 Modbus outputs for direct system tie-in
FAQ
What fluids can the RT-200 PRISM measure?
Built-in temperature-compensated equations convert refractive index into concentration values for Mono-Ethylene Glycol (MEG), Mono-Propylene Glycol (MPG), Sugar Content (BRIX), and Advanced Low Viscosity Fluid (ALV).
What temperature range does it operate in?
Sample temperature range is -20 to 120°C, which is why it suits sugar production and other high-temperature process monitoring beyond the standard RT-100 range.
How does it connect to a control system, and can it be checked remotely?
It outputs via (2) 4-20mA and RS-485 Modbus for PLC or DCS integration, and has built-in Bluetooth 5.0 that connects to the uPyxis mobile app for setup, diagnosis, and up to 56 days of stored historical readings at 1-minute intervals.
How is the sensor kept clean in fouling-prone streams?
An optional Ultra-Sonic RT-Series Cleaning Module (P/N 56208) is available for automated online cleaning in fouled or contaminated fluid streams.
What is the installation method?
The unit installs into a Tri-Clamp flow assembly with a 3/4″ NPT flange, and construction is 316L stainless steel with a sapphire window, rated IP67.
