2 Inline refractometer sensor
2.1 Sensor descripon
Figure 2.1 below shows a cutaway picture of a PR-23 inline refractometer sensor. The
measurement prism (A) is lush mounted to the surface of the probe tip. The prism
(A) and all the other optical components are ixed to the solid core module (C), which
is springloaded (D) against the prism gasket (B). The light source (L) is a yellow Light
Emitting Diode (LED), and the receiver is a CCD element (E). The electronics is pro-
tected against process heat by a thermal isolator (K) and cooling ins (G). The sensor
processor card (H) receives the raw data from the CCD element (E) and the Pt-1000
process temperature probe (F), then calculates the refractive index n
D
and the process
temperature T. This information is transmitted to the Indicating transmitter.
