Q. What does the probe monitor - how does it work?

A. All of our detectors and monitors measure the triboelectric effect that occurs when particles impact or closely pass by our probe.  Triboelectricity is a natural phenomenon which is the transfer of electrical charge between the particles and our probe.  We measure it in pico amps.  Over twenty years of experience has shown that there is a direct correlation between the signal strength and the concentration of dust in a pipe or duct when the velocity is relatively constant and the material being monitored is the same.  This has made our product perfect for measuring flow/no flow applications and monitoring the outlets of dust collectors.

Q. Can I monitor fume with any of your products?

A. No, our products measure particulate only, not fumes, gas or smoke.  We do have applications where the presence of fumes or smoke also indicates an increase in particulate, and our monitors have performed well.

Q. I already have a dust collector - how do I know which detector to use?

A. Typically we look for the following application data.  What type of a dust collector is it (Pulse Jet, Cartridge, etc.)? What is the process that the dust collector is collecting from? What is the temperature in the outlet of the collector? What are the dimensions of the outlet duct?  What is the purpose of monitoring the dust collector? From this information we can typically recommend which model will best suit your needs.

Q. What are the benefits of having a dust monitoring system?

A. Some of the benefits of a dust monitoring system include: reduced production down time from detecting the onset of leaks before they cause untimely shutdowns, labor savings by reducing the time to locate leaks, savings from extended bag or filter life by not doing change outs before they are necessary, peace of mind knowing that your dust emissions are being monitored around the clock.

Q. What is the warranty on a monitoring system?

A. We offer a one year warranty on all of our manufactured products.

Q. What temperatures can I use my monitor at?

A. There are two ways to look at this question.  All of our electronics are rated to operate in conditions not to exceed 150º F.  In applications where there are high temperatures, we use a remote probe which is installed in the duct; the electronics are then mounted away from the heat.  The remote probe can withstand higher temperatures depending on the insulator used.  For temperatures up to 450º F, we use our standard PFA insulator. We use a ceramic insulator in applications where the temperature is 450º F or higher.  The triboelectric effect starts to breakdown at temperatures above 1000º F.
