3.1 Requirements
For the mounting of the photometer and its additional components, the detailed dimension drawings must be ob-
served. The following provisions apply to the applications.
The photometer must be installed in the line at least 2 m away from sight glass or other sources of interfering
light.

Values
90° / 25° scattered light measurement at 650 nm (optional colour mea-
surement at 430 nm)
Ex db IIC T3/T4/T5/T6 Ga/Gb, temperature class depending on medium
temperature:
-20 ... +80 °C = T6
-20 ... +95 °C = T5
-20 ... +130 °C = T4
-20 ... +180 °C = T3
0 ... 100 % relative humidity
-20 ... +60 °C
Cooling depends on the maximum medium temperature (Tmed.) as well
as on the ambient temperature (Tenv.). The shaded area
temperatures above which cooling by means of an optional cooling ring is
required. The flow must be at least 0.2 l/min. at a coolant temperature of
max. 20 °C.
