Kotron^® Sentinel
Models 822, 832 and 842
RF Point Level Switches
DESCRIPTION
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.
FEATURES
• 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
