Elburn,
IL - Monitor Technologies
LLC is proud to introduce another product for
the SiloPatrol® Inventory
Management System, the Wireless Communication
Interface. With reliable and affordable technology,
the SiloPatrol Wireless
Communication Interface can be used to lower
the cost of installation and to overcome obstacles
that make hardwiring impractical or impossible.
The SiloPatrol Wireless
Communication Interface uses proven frequency-hopping
spread-spectrum technology, operating in the
900MHz band. Eliminating the need for wiring,
the Wireless Communication interface transmits
signals from PCs running SiloTrack Inventory
Management Software to individual or groups of SiloPatrol "smart" sensors.
The 900MHz band offers greater transmission distances,
better signal transmission through obstructions
and lower signal loss than other possible frequency
bands.
The SiloPatrol Wireless
Communication Interface can be utilized in numerous
applications and is very affordable . Using single
or multiple networks, over 100 sensors can be
connected with up to 16 sensors on one wireless
transceiver.
The SiloPatrol Wireless
Communication Interface is enclosed in a NEMA
4 enclosure suitable for indoor or outdoor mounting.
In addition, each transceiver includes both RS-485
and RS-232 interfaces. A choice of antenna and
power supply options are also available.
Elburn,
IL - Just released, Monitor Technologies' VibraFork vibratory
point level sensor for liquids provides reliable sensing
in a wide variety of applications in virtually any industry.
The
vibrating probe principle utilized by the VibraFork overcomes
typical application difficulties associated with changes
in material, electrical dielectric constant, temperature
or humidity. The VibraFork is
easy to setup and requires no calibration. A high excitation
frequency and a unique fork design provide excellent immunity
to external vibration.
The VibraFork line
of sensors has two versions, "Standard" and "Compact." The "Standard" version
has a traditional instrument housing and provides local indication
using a high-intensity bi-color LED and a relay output.
The "Compact" version
has a compact stainless steel housing with a small local LED.
A choice of outputs, solid state PNP/NPN, 2-wire AC or intrinsically
safe, are also available.
The
probe configurations available with either the "Standard" or "Compact" versions
include the standard probe (4.9 in/125 mm), "SHORT" probe
(2.7 in/69 mm) or pipe extension probe.
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.
