2.2 Construction and principle of operation
The construction of the model FLM-Cx level transmitter is illustrated in the version with
screw-in body. In the probe head
of the level transmitter are located the connection
terminals and the adjustment buttons protected by the cover
. The electrical connection
is made via an M16 x 1.5 cable gland
or M12 plug connection on the top of the probe
head and the ground connection
at the bottom of the probe head (see chapter 5.1
“Mounting” and 5.3 “Adjustment”).
On the guide tube
, for highly-adjustable mounting in the vessel, there is a screw-in
body
(compression fitting) or, for fixed mounting, a flange (not shown). The float
is
used for the continuous measurement of the product filling height or interface layer and is
held on the guide tube by an adjusting collar
.
The “BLM for bypass fitting” version is delivered without process connection and float.
