811-1005-E00 Datasheet, PDF (1/8 Pages) Magnetrol International, Inc. – Kotron® Model 811 RF Point Level Switch

Kotron^® Model 811
RF Point Level Switch
DESCRIPTION
The Kotron^® Model 811 Level Switch offers the user great
flexibility. The switch can be used either as a single alarm
relay with narrow differential or for control purposes
with an adjustable differential. Using the proven
RF Capacitance technology, the Model 811 provides
reliable operation for a broad range of applications.
FEATURES
• Useable for both narrow differential (alarm) and wide
differential (control)
• Intrinsically safe probe circuitry yields extra degree of
safety even with bare probes in hazardous media
• Remote mounting up to 150 feet (45 meters) with no
preamplifier on the probe provides protection from
high process temperatures or heavy vibration
• 10-amp DPDT relay provides flexibility for both alarm
and control applications
• Guard circuitry and probe reject buildup of media
• Useable with all Kotron probes for application flexibility
• LED shows relay status and aids in calibration and
troubleshooting
• 0 to 120 second time delay feature eliminates relay
chatter due to turbulence
• Field selectable high level/low level failsafe
• Conformally coated circuit boards reduce circuit
problems due to moisture and fungus
APPLICATIONS
• Clean or dirty liquids
• Viscous liquids
