Vaisala Refractometers
What is a refractometer?
Light bends when it crosses the boundary between one medium and another. Using this principle of refraction, known as the refractive index (RI), a refractometer measures the concentration of a particular substance in a liquid solution. Vaisala Refractometers are commonly used to determine the concentration of dissolved solids by making an optical measurement of a solution’s refractive index.
What do refractometers do?
Vaisala refractometers are a crucial element used in process control and industrial automation. Vaisala inline process measurement determines the liquid concentration or density to improve performance of all types of refining, manufacturing and quality control operations.
Vaisala liquid concentration measurement can be used in real time to predict the final concentration. This quick and accurate response can optimize production and reduce costs by reducing the variation in the mean average of product concentration.
How do refractometers work?
Vaisala refractometers have a sensor that measures the refractive index and the temperature of the process medium. The measurement is based on the refraction of light in the process medium, i.e. the critical angle of refraction using a yellow LED light source with the same wavelength (580 nm) as the sodium D line (nD.). The output of the transmitter is a 4 to 20 mA DC output signal proportional to process solution concentration, liquid density, Brix or another scale that has been selected for the instrument. Process data can also be downloaded to a computer via an Ethernet cable.
