TLS
Cable Suspended Float Level Sensors
■
One float gives a latched signal
between two different levels
■
Differential and switch level
points are easily field adjustable
■
Unique tumbling action
eliminates chatter
■
Mercury free design
The TLS-8 and TLS-6 cable
suspended float switches are
designed to provide the control
signals for a differential pump
control system. These top mounting
switches are suitable for use in a
wide variety of open tanks. The
control differential in the TLS-8 is
adjustable from 12 to 157 in. (300 to
4000 mm) while the TLS-6 has an
adjustable span of 8 to 39 in. (200 to
1000 mm).
■
Chemical Resistance
The ABS covered float and PVC
jacketed cable are compatible with
a wide range of liquids. However,
there are some liquids that are not
compatible with these materials.
ABS can be quickly damaged by
the following liquids:
Aromatics (benzene, toluene,
xylene) cause the float to dissolve.
Esters and ketones cause the float to
swell.
PVC cable can be used with the
following cautions:
Oils, especially vegetable oils and
fats, tend to absorb the placticizer of
the PVC jacketed cable which causes
it to stiffen.
