The PR53 inline refractometer is an instrument for measuring liquid concentration in the process line. The measurement is based on the refraction of light in the process medium, an accurate and safe way of measuring liquid concentration.
The inline process refractometer (1) measures the refractive index RI and the temperature of the process medium. This information is sent through the interconnecting cable (2) to the Indigo520 transmitter (3).
In most applications the PR53 prism keeps clean due to the self-cleaning effect. If coating occurs, your application requires a wash system. The wash system is controlled by Indigo520.
| To use PR53 refractometers with the Indigo520 transmitter, your transmitter needs to be ordered PR53-compatible. It is not possible to connect a refractometer to Indigo510 transmitters. |
