MAGNETROL
Kotron RF Capacitance Level Switches offer the industrial user a choice of alarm and control configurations. Both integral and remote electronics are available.
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.
