Float switch Series IGD finds application in liquid level
control in tanks and wells; it requires connection to
pumps (or other electrical equipment). The float switch
can be used with drinking water and sewage as well as
other liquids compatible with the components of the
product. Float switch Series IGD is spray and dust proof
thanks to a double sealing obtained by injection moulding
using the same material of construction for the body (non
toxic polypropylene).
Product reliability is ensured thanks to the sound expe-
rience of WATTS Cazzaniga in the sector as well as to the
stringent testing programme to which both the process
and product are submitted.
APPLICATION
It is important to make sure that they are no objects impe-
ding the float movement. If necessary, adjust the float arm
by suitably positioning it with relative counterweight.
It is good practice to position the float on the side
opposite to liquid inlet.
Electrical connection:
The three-pole cable (cable colour: Blue - Brown - Black)
allows float switch Series IGD to be used for emptying or
filling depending on the electrical connections as
described below:
- Emptying / Black - Brown connection / contact closes
with float at top
- Filling / Black - Brown connection / contact closes with
float at bottom.
INSTALLATION AND ELECTRICAL
CONNECTIONS
Float switch Series IGD can be used either for filling or
emptying tanks and wells.
The important factor is the length of the rotating arm
which determines the minimum and maximum liquid
levels. For such purpose, the arm length can be shortened
using the appropriate counterweight (CP/NSD).
Figures 1 and 2 illustrate the operation.
