KOTRON® 811 ® R.F. Point Level Sensor The Kotron Series 811 R.F. Point Level Sensor can be used as a single relay alarm (narrow differential) or control (wide differential) device which utilizes R.F. Capacitance technology for sensing liquids or bulk materials. There are no moving parts which come in contact with the medium. Handles temperatures up to 540°C when remote mounted FEATURES * Electronics offer alarm (narrow differential) and control (wide differential) capabilities making this unit ideal for a wide variety of applications. * Guard circuitry and probe reject build-up of conductive media. * Circuitry is designed and tested to meet IEC electrostatic discharge specification 801-2. * Usable with all Kotron probes for application flexibility. * Remote mounting up to 45 m (150 ft) with no preamplifier on the probe ensures protection from high process temperatures or heavy vibration. * 10A DPDT relay yields flexibility for most alarm and control schemes. * LED shows the status of the relay and aids in calibration and trouble-shooting. * 0 to 120 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 (IP 65), NEMA 4X (type 4 CSA), NEMA 4X/7/ 9. * Conformally coated circuit boards reduce circuit problems due to moisture and fungus.

Worldwide level and flow solutions PRINCIPLE OF OPERATION The amount of capacitance developed in any vessel, is determined by the size (surface area) of the probe, the distance from the probe to its ground reference, and the dielectric constant of the medium it is measuring. Assuming that the probe's mounting position and the dielectric of the medium are fixed, the amount of capacitance developed in any vessel becomes dependent upon the probe's diameter and length to determine its surface area. Adjusting the combination of the probe's diameter and length (and its proximity to the ground reference) in any given application, can generate the necessary capacitance required by the electronic circuitry. As the media rises and falls in the tank, the amount of capacitance developed between the sensing 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 a relay when they are equal. SELECTION DATA A complete measuring system consists of: 1.
