Kotron® 805 RF capacitance level transmitter

The Kotron® Model 805 Smart Transmitter is a loop-powered, 24 VDC, liquid-level transmitter based on proven RF Capacitance technology. Encompassing a number of significant engineering accomplishments, this high performance RF level transmitter is designed to provide reliable measurement performance well beyond that of competitive units.
The KOTRON Model 805 operates on a remarkably low amount of current. A microprocessor controls the measurement engine, drives the liquid crystal display, enables keypad operation, controls HART® communications and provides a 4–20 mA output.

A separate wiring compartment isolates the power/signal conductors from the electronics compartment via a sealed feed-through. The compartment is designed to maximize ease of wiring and includes surge and transient protection.

The unique enclosure is conveniently angled at 45° to facilitate ease of setup and configuration, and to maximize readability of the liquid crystal display.

RF Capacitance Technology


The liquid acts as an isolator between two conductors (probe and tank wall). When level rises, there is more gain of capacity into an analog or digital signal.

Probes

Kotron® RF Capacitance probes are available in many different configurations to handle a wide variety of application conditions. Generally insulated probes are used in conductive fluids (dielectric >10) and bare probes are used in non-conductive fluids (dielectric <10).

Operating principle


The KOTRON 805 combines the proven technology of RF Capacitance with advanced signal processing techniques and convenient user features. As level rises and falls in a tank or vessel, the amount of capacitance developed between the sensing probe and the tank wall (or ground) also rises and falls. This change in capacitance is digitized for display and HART® communications (optional) and converted into a proportional 4-20 mA analog output signal.
