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 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.
