Elburn,
IL - Monitor's Flo-Pad bin aeration
device fluidizes materials in bins, hoppers and silos.
The virtually maintenance free Flo-Pad uses multiple Easers
mounted on a single air plenum chamber inside the vessel
for a multi-directional air release.
Monitor's
Flo-Pad has many advantages over other bin aerators. The Flo-Pad
fluidizes materials without the noise and damaging vibration
caused by pneumatic or electric vibrators. Additionally, unlike
other types of aerators that use cotton or canvas to diffuse
the air, the Flo-Pad uses multiple Evassers, which are less
likely to be bound or clogged due to moisture. The Evassers
also have a standard neoprene boot that prevents material backflow
by expanding to let the pressurized air out and contracting
when the air is shut off.
The
most effective aeration of dry bulk materials is typically
achieved by the use of multiple rows of Flo-Pads, one row located
in each quadrant of the slopping bin bottom. The spacing between
rows and individual Flo-Pads can vary from application to application.
Units are available for high pressure and high temperature
applications.
Elburn,
IL - Monitor Technologies' BINATROL® diaphragm
switch is a durable and low-cost solution for detection
of product levels in dry material storage bins.
Monitor's
diaphragm switch can be used to eliminate bin overflow, maintain
a predetermined material level, indicate plugging of chutes
or conveyors or provide any of a number of level control functions.
The
flush mount, non-intrusive BINATROL® is ideally used when
vessel size or internal clearance is limited, or where protrusion
into a vessel is not acceptable. All installation and servicing,
including diaphragm replacement and sensitivity adjustment,
can be done from outside the vessel.
Monitor
offers a variety of diaphragm bin monitors that can be configured
with various switch sensitivities, diaphragm materials and
approval ratings.
The TrueCap® Model MK-2
RF Capacitance point level probe is designed to provide a superior
and stable sensitivity threshold making it suitable for a variety
of powder / bulk solids and some liquid or slurry applications.
Advanced features of the Model MK-2 include: > Automatic immunity to material build-up on
the probe by its driven shield design > Push-button calibration > Enhanced temperature compensation > Maximized reliability via smart sensing algorithms
like “self-validating” fail-safe protection > Visible status LED on ordinary location units > Versatility through a variety of configuration
options including: hazardous location version, split architecture
design, quick-connect process connection, stub probe, cable extensions,
solid extensions, Nylon® probes, Ryton® - equiv. probes,
etc.
A practical application for the TrueCap would be to use this level sensor where
a residual material build-up on a different sensor would cause a false material
level indication.
Principle of Operation for the TrueCap RF Capacitance Level
Probe:
The vessel wall and the active probe element establish an impedance reference
between each other when exposed to air which has a dielectric constant of 1.
When materials with a dielectric constant greater than 1 are in close proximity
to the probe, the impedance of the sensing field between the sensor and the vessel
wall will change. Once the amount of change exceeds a threshold that was electronically
determined during the calibration process, an output relay will either be energized
or de-energized depending upon the position of the fail-safe selector on the
probe’s electronic circuit board. A change of as little as .5 pico-farad
is all that is necessary for the probe to sense the presence of material.
