To determine fluid specific gravity,
add 0.1 to float specific gravity
in clean liquids and 0.3 to float
specific gravity in dirty or
viscous liquids.
The LVK-10 Series level switches
feature a small float displacement,
especially suited for narrow or restricted
areas. A standard
1
⁄8" NPT male fitting
allows for quick installation in either the
top or bottom of the tank or vessel. A
sealed SPST switch provides consistent
accuracy and high repeatability with the
effects of shock, vacuum or vibration
minimized. Extremely versatile, the
switch is user selectable as normally
open or normally closed by simply
removing the retaining clip and inverting
the position of the float.
For intermediate float displacement, the
LVK-20 Series will yield long life and
greater stability for a broad range of
level monitoring requirements. The
LVK-30 Series larger float displacement
is intended for use with liquids of high
viscosity, and is well suited for harsh
environments. Both models share the
standard features of the LVK-10.
See chart on page K-6 for maximum
voltage/current ratings.
