The PTR100 Inline Refractometer, marketed under the brand name PrismaTech, is designed using cutting-edge technology and high-quality components to measure, display, and control the concentration of transparent and non-transparent solutions.
The sensor unit of this device is installed directly on pipelines or tanks. It continuously measures the refractive index and temperature of the solution—two key factors that affect concentration. After performing complex calculations and a three-step calibration and compensation process, the device displays the solution concentration in Brix units.
In addition to displaying measurement results, the system transmits data via digital (RS485) or analog (0/4–20 mA) output ports to a local controller (such as a PLC). In the PrismaTech PTR100 model, the sensor unit and the control/display unit are separate.
One of the unique features of the Inline Refractometer is its automatic PID-based concentration control, which eliminates the need for an external local controller.
The set point and all controller parameters (such as proportional, integral, and derivative coefficients) are fully adjustable by the user.
Digital inline refractometers, or digital Brix meters, operate using an LED that illuminates the sample positioned above a prism. The refracted light is then detected by a sensor, allowing the device to determine the angle of refraction.
Because the measurement is temperature-dependent, the refractometer automatically applies temperature compensation through dedicated algorithms, converting the results into the refractive index or other specific parameters.
Compared to similar instruments, digital refractometers offer several advantages, including ease of use, automatic temperature correction, and adjustable measurement ranges. Smaller, portable refractometers are also available.
Digital refractometers can also be custom-designed for specific applications to improve performance, though this may limit their general versatility.
Digital inline refractometers are used for monitoring continuous processes and can be installed on tanks or piping systems.
They are designed to be durable and low-maintenance, capable of performing real-time concentration and Brix measurements to control the product during the raw, intermediate, and final stages of production.
These instruments are crucial tools for quality control, especially in cases where a fast and precise response is needed to optimize a process or to regulate sensitive stages such as purification or product quality assurance.
