Models 822, 832 and 842
RF Point Level Switches
D E S C R I P T I O N
The Sentinel is a powerful multi-point level switch. The
microprocessor-based circuitry has non-volatile memory,
to protect against data loss. Powerful diagnostics check
all major aspects of the system while MagneCal™ offers
the user the advantage that one small level change is
needed to calibrate.
F E A T U R E S
•
Optional intrinsically safe probe circuitry (with
on-board barriers) allows safe use, even with bare
probes in hazardous media
•
Intrinsically safe remote mount models up to
800 feet (240 meters) of cable
•
Integral or standard remote mount up to
2500 feet (760 meters) for application flexibility
•
Two to four DPDT relays yield wide application
flexibility for most alarm and control operation
•
Relays 2 and 3, Series 832/842 models, may be used
for lead/lag pump sequencing
•
Time delay eliminates relay chatter due to turbulence.
•
Usable with all Kotron probes for excellent application
flexibility
•
3-button/4-digit LED data entry of all parameters
•
One small level change (2% of span) needed for initial
calibration in most cases
•
Powerful self-diagnostics check the system, minimizing
the need for routine maintenance checks
•
Diagnostics check the integrity of the probe
•
One relay may be dedicated as a diagnostic alarm
•
Corrosives
