Vertical Mounting
Vertically mounted probes provide the capability to adjust
the control point up or down a section of probe rod by
means of calibration adjustments within the unit’s amplifier.
The vertical mounting of a probe rod is the preferred
method for application involving coating conductive type
liquids or conductive solids.
Vertically mounted probes should be installed so that the
end of the probe rod is at least 2 inches (51 mm) below
the desired level control point with conductive materials or
4 inches (102 mm) below with non-conductive materials.
Refer to Figure 5.

Mounting Procedure
Kotron RF Point Level Switches with probes up to and
including 12 inches (305 mm) in length are shipped pre-
assembled. Units with probes over 12 inches (305 mm) in
length are shipped unassembled to avoid damage during
transit. They must be assembled before mounting. Follow
the mounting procedure for your particular case.
NOTE: Before beginning mounting procedures, make sure the power
source to the unit is turned off.
