The LVCN700 Series general
purpose ultrasonic switch provides
non-contact level detection from up
to 8 m (26') away, and has 3 relay
outputs. Each relay can be
configured on a single setpoint
alarm, 2 latched setpoints for
automatic fill or empty including
lead-lag, or 2 independent setpoints
for out-of-bounds alarms. In addition,
relays 1 and 2 can be interlocked for
relay alternation or duplex operation.
The switch is well suited for a broad
range of corrosive, waste and slurrytype media, and is broadly selected
for atmospheric day tank, pump lift
station and waste sump applications.
