9.4.5 PR-23-AP mounting specifics

The Probe refractometer PR-23-AP is primarily designed for mounting in a tank wall.
To ensure that the measurement is representative and that the prism stays clean, the
probe should be installed close to a stirrer.
Probe refractometer type PR-23-AP-T is connected to the process by a 2 1/2" 3A san-
itary clamp, Figure 9.10. PR-23-AP-R is connected by 4" sanitary clamp.
Note: For higher process (or ambient) temperatures, use instead a flush mounted
sensor, where the electronics in the sensor head are farther away from the process
heat, Figure 9.11.
