Protecting Filter Media & Blowers In Dust collection Systems
IL –Monitor Technologies LLC is pleased to announce the availability of its DustAlarm(R) broken bag detector. This instrument is used by dust collection systems in a wide range of applications to monitor the exhaust of bag houses and other types of dust collection systems to identify problems with filter media and other sources of increases in dust emissions.
The DustAlarm broken bag detector uses time-proven triboelectric technology to continuously monitor the level of dust emission in dust collection system exhausts. When an increase in emission level exceeds the user adjusted setting an alarm is triggered as indicated by the unit's output relay changing state. The DustAlarm is provided with a unique extended insulator to guard against material build-up problems, as well as a unique quick-disconnect mounting connection fitting to facility quick and easy maintenance when needed.
Monitor Technologies LLC is a leading supplier of level, flow, particle emission and aeration instrumentation for the worldwide powder and bulk solids market. The experience and market knowledge gained over almost five decades has earned Monitor a reputation for providing high quality, reliable product solutions. Monitor is located in Elburn Illinois, give us a call today and let us put our creative solutions to work for you!

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,
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
Principle of Operation for the TrueCap RF Capacitance Level
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.
