Kotron® Sentinel Model 804 RF Level Transmitter D E S C R I P T I O N The Sentinel is a unique, powerful level transmitter. The leading-edge microprocessor-based circuitry has nonvolatile memory. The display and keypad simplify calibration and setup of the instrument. Powerful diagnostics check all functions of the system, simplifying troubleshooting. MagneCal™ offers the user the greatest improvement in RF Capacitance—one small level change is needed to calibrate. F E A T U R E S • Two or four SPDT relays with gold flash contacts for alarm and control operation. • Optional intrinsically safe probe circuitry (with on-board barriers). • 16-button keypad and 2 × 16 LCD display. • Isolated 4–20 mA output includes an active/passive mode. • Relays can be configured for sequential or lead/lag pump control. • One small level change (2% of span) needed for initial probe calibration. A P P L I C A T I O N S • Continuous level measurement • Interface measurement • 4–20 mA and up to eight control points can be programmed with no level change. • Powerful self-diagnostics check the system, including probe. • Relay #1 can be dedicated as a diagnostics relay. • Hydrocarbons and solvents • Slurries • Acids • High temperature/pressure liquids T E C H N O L O G Y The amount of capacitance developed in any vessel is determined by: the size (surface area) of the probe; the As the media rises and falls in the tank, the amount of capacitance developed between the probe and the distance from the probe to its ground reference; and the dielectric constant of the medium being measured. ground reference also changes. The capacitance signal is converted to a frequency proportional to the change in Considering that the probe’s mounting position is fixed level. The amplifier then converts this digital signal into an isolated 4–20 mA analog output signal. and the dielectric 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 with media.
