 Kotron® 810 - Alarm with Guarded, IS Probe   Printer Friendly Version
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. These units are integral systems with the sensing probe mounted with the electronics.

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.
