9 Sensor specifications
Note: For the specifications of the PR-23-SD sensor for Safe-Drive™ system, see Sec-
tions 11.2 and 10.4.

9.1 Sensor compatibility

Electrically: All the PR-23 refractometer sensors are interchangeable. The PR-23
sensors are not interchangeable with the PR-01 and PR-03 range sensors. Further-
more, the PR-23 sensors are not compatible with the PR-01 / PR-03 indicating trans-
mitter IT-R.
Mechanically: The sanitary process refractometer PR-23-AC-62-HSS fits the same
2 1/2" sanitary process connection as the sanitary refractometer PR-03-A62-HSS.

9.2 Sensor rangeability

The refractive index standard range of a PR-23 refractometer sensor is 1.320–1.530
(corresponds to 0–100 Brix), Figure 9.2.
