50-605 Kotron RF Point Model 80/81 Level Switches

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.
