& LITY QUA LESS D E T R ASSUVICE COS R E S 01 ® ISO 90 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. KOTRON ® 810 R.F. Point Level Sensor 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.

Worldwide level and flow solutions 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.
