2.0 Installation
Caution: Please read the entire installation section carefully prior to
starting installation.
2.1 Unpacking
Unpack the instrument carefully. Make sure all compo-
nents have been removed from the packing material.
Inspect all components for damage. Report any concealed
damage to the carrier within 24 hours. Check the contents
against the packing slip and report any discrepancies to the
factory. Check the nameplate model number to be sure it
agrees with the packing slip and purchase order. Check
and record the serial number for future reference when
ordering parts.
2.2 Installation Location
Kotron RF Point Level Switches should be located for easy
access for service, calibration and monitoring. Switches
should not be exposed to ambient temperatures below
-40° F (-40° C) or above +160° F (+71° C). Special pre-
caution should be made to prevent exposure to corrosive
atmosphere, excessive vibration, shock or physical damage.
It is common practice to use the metal tank wall as the
reference electrode. In such cases, it is required that the
probe housing makes a good electrical connection to the
tank wall. If there is any doubt about this connection due
to the use of PTFE thread tape, gaskets, paint, rust, or any
other reason, a separate strap should be installed between
the probe housing and the tank.
Caution: This unit contains CMOS electronics which may be
damaged by static electricity. Do not touch any semi-
conductor devices unless you are properly grounded.
2.2.1 Metal Walled Tanks
On water-based liquids, there should be no problem with
sensitivity or linearity. With non-conductive, low dielectric
media, sensitivity can be enhanced by locating the probe
close to and parallel with the tank wall. If this is not prac-
tical, a concentric ground tube surrounding the probe,
sometimes called a stilling well, may be a solution.
