General information
2.1.2 Warning labels
Read all labels and tags attached to the instrument. Failure to do so may result in personal
injury or damage to the instrument.
2.2 Areas of application
Figure 2 Overview
The TSS EX1 sc sensor is an extremely accurate turbidity and solid sensor made from
stainless steel for color-independent measurement of highly concentrated sludges.
This sensor was specially developed for use in ATEX zones up to 1 and 21 maximum
(equipment group II, category 2) and is available in a basin version or an installation
version (TriClamp).
2.3 Measuring principle
2.3.1 Turbidity according to DIN standards
Turbidity is measured in accordance with DIN standard EN 27027 (ISO 7027) and is
calibrated by the manufacturer. Measurement is exceptionally simple and accurate.
2.3.2 Measurement of solids according to plant-specific curves
Software-based optimization routines enable extremely precise simulation of
medium-specific calibration curves with few calibration points. Usually, a single calibration
point is sufficient.
This symbol may have been attached to the device, and in such cases it references the instruction manual for
