The Kotron® Series 810 R.F. Point Level Sensor is a single
relay, alarm (narrow differential) device which utilizes R.F.
capacitance technology for sensing liquid or bulk materials.
The alarm point is tip sensitive in conductive media, and
adjustable in non-conductive media. There are no moving
parts which come in contact with the medium. These units
are integral systems with the sensing probe mounted with
the electronics.

Excellent rejection of build - up even of
conductive media
FEATURES
* Guard circuit and probe reject build-up of conductive
media.
* Circuitry designed and tested to IEC electrostatic
discharge spec. 801-2.
* Probe is ideal for high pressure applications - rated to
240 bar at 20°C (3500 PSIG at 70°F), 120 bar at 90°C
(1750 PSIG at 200°F).
* Intrinsically safe probe circuitry allows safe use even
with bare probes in hazardous media.
* 5A DPDT relay is usable in most standard alarm
applications.
* LED shows the status of the relay and aids in calibration
and trouble-shooting.
* Zero to 45 second time delay feature eliminates relay
"chatter" due to turbulence.
* Field selectable high level/low level failsafe provides
NO or NC contacts in de-energized state for either failsafe condition.
* Cast aluminum, anti corrosive painted enclosure is rated
CENELEC EEx d (IP 65) NEMA 4X / 7/9.
* Horizontal or vertical mounting.

PRINCIPLE OF OPERATION
As the media rises and falls in the tank, the amount of
capacitance developed between the probe and the ground
reference also rises and falls. This change in capacitance is
converted into a pulse waveform proportional to the level
change. The amplifier then compares the pulse waveform to
the adjustable set point and changes the state of the relay
when they are equal. In conductive media the amount of
capacitance generated by contact of the probe with the
medium will trip the relay immediately.
PROBE LENGTH VS. DIELECTRIC CONSTANT
If the geometry of the application requires a probe shorter than 305 mm (12") of active length, consult the chart to determine the
minimum dielectric constant in which it can be used.
