DESCRIPTION
The Kotron II Series 801 Transmitter is a new generation RF
Capacitance transmitter that offers the user unparalleled
power. The Series 801 can interface with two separate
vessels, essentially making it a mini-multiplexer, while soft-
ware mathematics allows for the Sum or Difference of the
two signals.

PRINCIPLE OF OPERATION
The amount of capacitance developed in any application is
determined by the size (surface area) of the probe, the dis-
tance from the probe to its ground reference, and the dielec-
tric constant of the medium being measured.
Considering that the probe's mounting position is fixed, and
the dielectric value of the medium is constant, the amount of
capacitance developed in any vessel becomes dependent
upon the probe's diameter and length.
As a medium rises and falls in the tank, the amount of
capacitance developed between the sensing probe and the
ground reference also rises and falls. The Pulsatel circuit,
mounted on the probe, changes the capacitance signal to a
digital signal which can then be sent to the main electronics
located up to 2500 feet (760 M) away.
