 Kotron® 801 General Purpose Controller with Relays   Printer Friendly Version
The Kotron Model 801 Transmitter is a multi-function transmitter that offers the user unparalleled power. The preamplifier circuit provides installation flexibility of a 2500 feet maximum remote distance. The Model 801 can interface with two separate vessels, essentially making it a mini-multiplexer, while software mathematics allow for the sum or differential of the two signals.

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.
