THE COOL ONE 8
The level sensor THE COOL ONE is available in three different
versions (types 1–3) (see Fig. 1).
Types 1 and 2 have a clampable screw-in body (thread 3/4), with
which the individual response length for each container can be
adjusted by moving the probe tube in the screw-in body. These
two types are highly suitable for installation above the liquid
level. (see Fig. 1 and Chap. 4 "Installation")
Type 3 is intended for installation laterally and below a liquid
level. This level sensor has a fixed screw-in piece (thread 3/8),
and the response length cannot be varied. (see Fig. 1)
