1.0 Introduction
The Kotron Mo el 810 RF Point Level Sensor can be
utilize in liqui or bulk material applications. There are
no moving parts in contact with the me ium. These units
are integral systems with the sensing probe mounte with
the electronics. Guar e probes are utilize to minimize
effect of buil up on the probe.
1.1 Principle of Operation
As the me ium covers the probe, the amount of capaci-
tance evelope between the probe an groun changes.
This change in capacitance is converte into a relay action.
As the me ium rains from the sensing probe, the relay
position reverses.
2.0 Installation
This section provi es etaile proce ures for properly
installing point level sensors.
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.
2.1 Unpacking
Unpack the instrument carefully. Inspect all components
for amage. Report any conceale amage to carrier
within 24 hours. Check the contents of the packing slip
against purchase or er. Check an recor the mo el
number against serial number for future reference when
or ering parts.

2.2 Electrostatic Discharge (ESD)
Handling Procedure
Magnetrol’s electronic instruments are manufacture to the
highest quality stan ar s. These instruments use electronic
components that may be amage by static electricity pre-
sent in most work environments.
The following steps are recommen e to re uce the risk of
component failure ue to electrostatic ischarge.
• Ship an store circuit boar s in anti-static bags. If an anti-
static bag is not available, wrap the boar in aluminum
foil. Do not place boar s on foam packing materials.
• Use a groun ing wrist strap when installing an removing
circuit boar s. A groun e workstation is recommen e .
• Han le circuit boar s only by the e ges. Do not touch
components or connector pins.
• Make sure that all electrical connections are completely
ma e an none are partial or floating. Groun all
equipment to a goo , earth groun .
2.3 Installation
2.3.1 Installation Location
Kotron point sensors shoul be locate in areas allowing
easy access for service, calibration an monitoring. Units
shoul not be expose to ambient temperatures above
+160° F (+71° C) or below -40° F (-40° C). Special pre-
caution shoul be taken to prevent exposure to corrosive
atmosphere, excessive vibration, shock or physical amage.
Sensing probes shoul be locate close to the tank wall for
greatest sensitivity in non-con uctive me ia. Probes shoul
be isolate from severe motion in the tank, because surface
turbulence may cause signal eviation.
NOTE: Do not attempt to disassemble probe from housing
until the wires have been disconnected and the
electronic module has been removed. Consult Section 3.1,
Troubleshooting on page 8.

2.3.2 robe Length
If the geometry of your application requires a probe short-
er than 12" (305 mm) of active length, refer to Figure 1
below to etermine the minimum ielectric constant in
which it can be use .
2.4 Mounting
When installing, apply wrench to mounting glan only.
Guar element shoul be locate free of nozzle.
Caution: When a probe is used in an abrasive medium, inspect the
probe at least annually for visible surface wear. In case any
wear is found, replace the probe or consult the factory.
2.4.1 Horizontal Mounting
Unit will signal at probe level. Refer to Figures 2 an 3.
Caution: Do NOT horizontally mount the unit in a nozzle deeper than
3" (75 mm). Refer to Figures 2 and 3. The medium may
build up in the nozzle and cause false actuation.
2.4.2 Vertical Mounting
As me ium rises on the probe, the unit will signal at a
point etermine by the calibration of the unit an the
ielectric constant of the me ium. In con uctive me ia,
the actuation point will be at the tip of the probe over a
wi e range of a justment. Refer to Figure 4.
INSTALLATION INSTRUCTIONS
1. Threa amplifier assembly into mounting bushing on tank
using suitable pipe compoun or threa tape. Assembly
may also be attache to a flange an bolte to the vessel
using a suitable gasket.
2. Tighten securely, being certain that the wrench is applie
ONLY to the mounting glan . Refer to Figures 2
through 4.
