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.

The
SafePoint rotary paddle level switch with a self-validating design
detects material presence plus continuously monitors its own ability
to function. The analysis includes sensor health and system power
failure, which makes the SafePoint truly “fail-safe”.
The SafePoint incorporates patented use of Hall-Effect technology,
dual outputs to indicate both material presence and unit health,
and microcontroller technology to continuously protect bulk solids
processing and storage from the consequences of unknown sensor
failure by providing immediate indication of a sensor failure
and confirmation of proper operation.
Other practical features of the SafePoint include rugged construction,
motor shut-off when paddle becomes impeded to maximize motor life, twist On/Off
cover for bolt free removal, and local status indicating light (except hazardous
location models)
A practical application for the SafePoint would be to use this "true"
fail-safe product if undetected sensor failure could result in a
catastrophic process problem.
