install SoniGuard and turn power on. It will be working for you! It's
that simple to use.
Ultrasonic PLUGGED CHUTE
and Point Level Monitor:
Plugged Chute control, Bin or Hopper High or Low level control, Material
Flow control, Conveyor control, Web Break detection, Vehicle Position
detection, Foam Rise, etc.
Monitors blockage of material flow and single (point) level of bulk material in bins, hoppers, chutes,
conveyors, tanks, etc. Two ultrasonic sensors are placed facing each other in opposite walls of
the monitored vessel. When the material rises to this level or exceeds
it, an internal double pole, double throw relay will trip (after delay). The relay will revert to opposite state
(after delay) when material level drops below the ultrasonic sensors. Thus, SoniGuard
indicates presence or absence of material or objects in between the
sensors. When used as a plugged chute monitor, there
are two adjustments that allow delays of output control relay trip,
necessary for proper detection of material blockage.

SoniGuard operates using ultrasonic signal, transmitted from one sensor
toward the opposite sensor, placed in a direct line of sight. The signal
is a strong, high frequency acoustic burst (not detectable by humans). The
signal is modulated and coded for reliable operation. The sensors are
typically installed flush with the hopper walls, they do not need to
protrude inside. However, they can not transmit through the walls. The
signal path is interrupted when there is material accumulation in between
the sensors. With no material present, the signal travels freely between
sensors are identical, any of the two can be used as transmitter or
SoniGuard is a versatile monitor that operates reliably in vast variety of
materials, light or dense, regardless of color or transparency of the
monitored material. The operation is not affected
by radio or microwave signal, radars, acoustic noise. SoniGuard
allows adjustment of the relay trip by time Delay on Break and Delay on Make.
These delays prevent untimely contact triggering. Both delay adjustments
are clearly marked on the circuit boards. Signal Gain adjustment (also
located and marked on the circuit board) allows monitoring of entire
spectrum of bulk materials. There are three lights on the circuit
board to indicate operation status - Red LED indicates whether material is
present or not, Yellow LED indicates status of the output relay, Green LED
is a Power-On indication.
