804-R010-230 Datasheet, PDF (1/8 Pages) Magnetrol International, Inc. – Kotron® Sentinel Model 804 RF Level Transmitter
Kotron® Sentinel
Model 804
RF Level Transmitter
DESCRIPTION
The Sentinel is a unique, powerful level transmitter. The
leading-edge microprocessor-based circuitry has non-
volatile memory. The display and keypad simplify
calibration and setup of the instrument. Powerful diag-
nostics 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.
FEATURES
• 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.
• 4–20 mA and up to eight control points can be pro-
grammed with no level change.
• Powerful self-diagnostics check the system, including
probe.
• Relay #1 can be dedicated as a diagnostics relay.
APPLICATIONS
• Continuous level measurement
• Interface measurement
• Hydrocarbons and solvents
• Slurries
• Acids
• High temperature/pressure liquids
