Digital Process Refractometer PR-01-S is a heavy duty instrument for measuring the concentration of a wide range of liquids with an accuracy of ± 0.0002 R.I. (corresponding to ± 0.1% by weight).
Digital Process Refractometer PR-01-S is a heavy duty instrument for measuring the concentration of a wide range of liquids with an accuracy of ± 0.0002 R.I. (corresponding to ± 0.1% by weight).

It determines the Refractive Index (R.I.) of the process solution by measuring the critical angle of refraction, which changes the concentration. The critical angle of refraction is measured by a digital CCD-camera in a rugged steel probe. The probe is designed for demanding process conditions, high temperatures (max. 150°C), pressure (max. 25 bar) and vibration. Due to the true digital measuring principle the calibration will not change with time; once the sensor is calibrated to desired range, there is no need for recalibration.

All relevant information like concentration percentage, process temperature and diagnostics messages can be seen at a glance on the Indicating Transmitter display. The output signals are 4-20 mA proportional to the process concentration. In addition, a serial output signal (RS 485 or RS 232) is available as standard.
