3.2.2 … of the high-level sensor SEPARIX-T L Plus
The SEPARIX-T L Plus is not permitted to be used in aggressive media.
The high-level sensor is suspended on its cable (6) in the light liquid separator (3) in dis-
tance to the inlet because there is an increased risk of contamination or disturbance by
splashing fluids (see
Figure 4: SEPARIX-T, installation
). The correct fastening method and mate-
rials depend on local installation rules and regulations and the material used for the
separator (concrete, plastic, metal, etc.).
The measuring transducer detects when the sensor tip of the connected high-level sensor
(5) is immersed into fluid (whether light liquid or water). This response point (4) is marked
on the outside of the sensor by a circular groove. The high-level sensor must be installed
in such a way that the response point (4) is at the height above which an alarm is to be
triggered by a rising liquid level.
The high-level sensor is equipped with an undetachable blue cable (6) (2 x 0.5 mm²) with a
length of 5 m. This cable can be shortened or extended up to 250 m with the use of a junc-
tion box (1) suitable for the environmental conditions concerned and an extension cable (2).
