Kotron® Model 811 RF Point Level Switch DESCRIPTION The Kotron® Model 811 Level Switch offers the user great flexibility. The switch can be used either as a single alarm relay with narrow differential or for control purposes with an adjustable differential. Using the proven RF Capacitance technology, the Model 811 provides reliable operation for a broad range of applications. FEATURES • Useable for both narrow differential (alarm) and wide differential (control) • Intrinsically safe probe circuitry yields extra degree of safety even with bare probes in hazardous media • Remote mounting up to 150 feet (45 meters) with no preamplifier on the probe provides protection from high process temperatures or heavy vibration • 10-amp DPDT relay provides flexibility for both alarm and control applications • Guard circuitry and probe reject buildup of media • Useable with all Kotron probes for application flexibility • LED shows relay status and aids in calibration and troubleshooting • 0 to 120 second time delay feature eliminates relay chatter due to turbulence • Field selectable high level/low level failsafe • Conformally coated circuit boards reduce circuit problems due to moisture and fungus APPLICATIONS • Clean or dirty liquids • Viscous liquids • Light slurries • Corrosive liquids • High temperature/pressure liquids • Hydrocarbons and solvents • Acids and caustics • Foods and beverages TYPICAL APPLICATION Pump/Valve Control The Model 811 handles alarm applications as well as pump/valve control applications with a wide or adjustable differential. Pump control Coating Rejection Conductive coating The Model 811 provides rejection of conductive buildup by utilizing a guarded probe. Coating rejection circuit is standard on all units. Intrinsically Safe Non-hazardous Area Hazardous Area The Model 811-1X06-E0X is inherently intrinsically safe when the main amplifier is mounted in a non-hazardous area. Barriers are included in the 811 electronics eliminating the need for separate barriers. 811-1X06-E0X Intrinsically safe circuit 2 TECHNOLOGY 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, and the dielectric of the medium being measured. Considering that the probe’s mounting position is fixed and that the dielectric value of the medium is constant, then the amount of capacitance developed in any vessel becomes dependent upon the amount of the probe which is covered by the media. As media rises and falls in the tank, the amount of capacitance developed between the sensing probe and the ground also rises and falls. This change in capacitance is compared to the adjustable set point and changes the state of a relay when they are equal.
