November/December 2005 : DustAlarm®

 

DustAlarm®

Is Your
Dust Collector
Working?

Elburn, IL – Dust collectors (baghouses) do not always operate at optimal efficiency. Filter material degrades, bags begin to tear and sometimes they fail catastrophically. To avoid dust emissions that exceed regional and federal EPA mandates, and to assist with preventative maintenance, many industries and manufacturers have used the DustAlarm® broken bag detector from Monitor Technologies LLC.

This state-of-the-art instrument uses triboelectric detection techniques to continuously monitor the emissions within the exhaust dust of your baghouse. The DustAlarm can help reduce maintenance costs, can keep clean-up costs to a minimum and help ensure you are complying with EPA regulations and mandates. Today’s DustAlarm broken bag detector includes features such as:

Proven triboelectric technology. Protect blowers from damage and replace filters timely.

High voltage AC (115/230VAC) and low voltage power supply (10-32VDC) available.

Adjustable sensitivity, alarm setpoint and time delay.

Integral electronics assembly or remote electronics option available.

Quick-disconnect mounting is standard for easy cleaning.

316 stainless steel probe with specially designed insulator.

Handles up to 450∞ F (232∞ C) process temperatures with remote electronics option.

Spotlight: RF Capacitance Level Sensor
TrueCap Level SensorsTrueCap Light  
TrueCap® MK-2
Advanced RF Capacitance Level 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.
