The T10 float level switch offers industrial and municipal
users a low cost solution to wide differential level
applications. The patented moving ballast causes a flipping
motion of the float to provide positive switching action even
under turbulent conditions. Recommended for use in either
clean or dirty liquids, it is ideal for use in both sump control,
wet well applications and pilot systems.

Differential band 6 m (20 ft), 12 m (40 ft) or 18 m (60 ft),
determined by the length of the cable.
May be wired for automatic fill or empty cycles.
Dry contact switch mechanism.
Cable CSA (SJTO) approved.
Switch chatter eliminated with moving ballast.
Single float with simple control circuit eliminates the
need for latching devices or double switching with 2
units.
Provides positive switching action, even in turbulent
conditions.
Cable anchoring point protected by an adjustable strain
relief.
All wetted parts in PVC for increased resistance to water
based chemicals.
Heavy duty construction requires no maintenance when
properly mounted.
Mounts easily by cable tie (included) or optional cable
weight.

PRINCIPLE
OF OPERATION
Figure 1:
T10 level switches contain a dry
contact switch with a swinging
ballast. The cable on the float
is anchored in the tank at the
midpoint of the differential band.
Figure 3:
Since the float remains in this
position even under turbulent
conditions, switch chatter is
eliminated.
Figure 5:
As the highest point of the
differential is reached, the cable
is again pulled taut, tilting the
float, causing the ballast to swing
back to its original position in the
float.
The float flips, causing the
switch contacts to return to their
original state. This cycle repeats
as the level changes.
Figure 2
Figure 2:
As the level falls to the lowest
point of the differential, the cable
is pulled taut, tilting the float,
causing the ballast to swing to
the opposite end of the float.
The float reacts in a flipping
action which causes the switch
contacts to change state. The
minimum level recommended is
152 mm (6.00).
Figure 4
Figure 4:
Contacts have not yet changed
state with rise in level.
Figure 6
Figure 6:
The differential band equals
twice the length of cable from its
point of attachment to the strain
relief, to the point at which it is
anchored.
For an alarm function, use a
minimum differential band of
229 mm (9.00).
