10.1 Sensor compatibility
Electrically: All PR‑23 sensors are interchangeable. The PR‑23 sensors are not
interchangeable with the PR‑01 and PR‑03 range sensors. Furthermore, PR‑23 sensors are
not compatible with the PR‑01 / PR‑03 indicating transmitter IT‑R.
Mechanically: The sanitary process refractometer PR‑23‑AC‑62‑HSS fits the same 2.5 in
sanitary process connection as the sanitary refractometer PR‑03‑A62‑HSS.
10.2 Sensor rangeability
The standard refractive index range of a PR‑23 sensor is 1.320 ... 1.530 (corresponds to
0 ... 100 Brix), shown in the following figure.
