February 2010: VibraRod™ Vibratory
Bin Level Sensor
VibraRod™ Level
Indicator Now With A
Universal Power Supply
Monitor Technologies’ VibraRod™ vibratory
type bin / silo sensor is a very reliable point level
indicator that can be used in a wide variety of applications
within the powder and bulk solids markets. Monitor’s
VibraRod unit is ideal as a high level indicator for
bulk solids as low as 3.12 lbs/ft3 (0.05 kg/dm3)
with a maximum particle size of 3/8 inches (9.5 mm).
The ordinary location VibraRod™ point
level sensor now has a universal power supply (20-255V
AC/DC). “This allows customers with various power
supply requirements to specify a single part number
for all of their different voltage requirements,” says
Greg DeRudder, Product Manager for Monitor Technologies. The
VibraRod also has many other useful features such as
a single-element probe design, requires no calibration
and a choice of probe configurations. The single-element
probe design helps eliminate false signals that typically
exist when material builds up between the tines of “tuning
fork” style probes. Also, the vibrating
action of the VibraRod tends to self-clean the probe
for most materials.
The standard length of the inserted
portion of the probe for the VibraRod™ is approximately
8 inches (203 mm). Pipe and cable extension units
are also available for longer lengths in top mounted
applications. The pipe extension unit uses 1” stainless
steel pipe to extend the vibrating sensor into the
vessel, provides structural strength, and affords a
means to secure the assembly to the vessel. The
cable extension is a polyethylene coated steel cable.

Microwave solids flow detectors can
be used in a variety of applications including feed mills & grain processing,
consumer foods (cereal, sugar, cocoa, coffee), chemicals & pesticides
and more. For example, one company uses Monitor’s Model SFD-2
solids flow detector to verify the flow of feed pellets through their
various transport lines which involves a process where a horizontal
screw auger is conveying pellets over to a vertical gravity chute. The
chute then directs the pellets to a process down below. They have
carefully placed the SFD-2 so that it detects the pellets as they
fall directly across the sensor face. (See Below)
The Model SFI and SFD-2 line of solids flow detectors
from Monitor Technologies, LLC provide analog or relay outputs
to indicate the flow / no-flow condition of powder and bulk solids
materials in chutes and pneumatic conveying lines. Using
microwave Doppler radar technology these units are non-invasive
plus extremely reliable and rugged to withstand the rigors of the
installation and your process extremes. From automated systems
with pneumatic lines to gravity chutes, solids flow monitors can
help to improve process performance. They can assist in detecting
flow problems, as well as, enhance the level of automation at a
facility like turning a conveyor on or off.
