Kotron® Model 810 RF Point Level Switch DESCRIPTION The Kotron Model 810 is a single point switch for alarm applications using RF Capacitance technology. A guarded probe and intrinsically safe probe circuit are provided. The alarm point is tip sensitive in conductive media and adjustable in non-conductive media. These units are integral systems with the sensing probe mounted with the electronics. FEATURES • Sensitive and stable electronics detect even the most non-conductive hydrocarbons • Guard circuit and probe reject build-up of conductive media • Equipped with a 316 SS/Ryton probe available in 18" (450 mm) and 36" (920 mm) lengths • Probe is ideal for high pressure applications – rated to 3500 psig at +100° F (240 bar at +40° C), 1750 psig at +200° F (120 bar at +95° C) APPLICATIONS • Intrinsically safe probe circuitry allows safe use 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 troubleshooting • Zero to 45 second time delay feature eliminates relay "chatter" due to turbulence • Field selectable high level/low level failsafe • Clean or dirty liquids • Viscous liquids • Light slurries • High temperature/pressure liquids • Foods and beverages • Powders and granulars • Hydrocarbons and solvents • Acids and caustics 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 measured in the electronics. When the capacitance measurement is the same as the setpoint, an alarm occurs.
