Voice Description

I've been told that I sound like Principal Skinner (The Simpsons character as voiced by Harry Shearer). I aspire to be as clear and crisp as Bill Kurtis (NPR and CBS) or Carl Kasell (NPR). As a backstage announcer at some large business conventions, I was nicknamed VOG (voice of god [lower case "g" please]). I am a business owner in the gas technology field so technical reads and industrial site safety videos (I've had to sit through many) are very familiar to me. VoiceCoaches put me through many tests and I found that I'm not half bad at documentaries and character acting for books ... who knew?! My tag line says "the unknown voice behind the curtain" which means I am not looking for fame and fortune; I do enjoy it when people come up to me and say "you sound just like that guy on the radio." Sometimes I just say "thank you", other times I say "well, that's because, that is me." You'll have to ask me about the time my mother was asked about her last name being the same as "that guy on the radio" (circa 1976).

Question 2

35K0104R0, NOx Detector 0-800ppm CLD 200 cc/min, Replaces Rosemount 659754 and Tyco 1021326-100-TES

cms_admin · Accepted Answer

If you've stumbled on to this FAQ, you must have a Rosemount NGA-2000 CLD analyzer to measure NOX either dry or wet (referring to the WCLD version). The detector portion of this analyzer is OEM p/n: 659754 (obsolete) and is sold by us under this part number: 35K0104R0. It is the same OEM detector and fully compatible with your NGA-2000 or uCEMS. I'd like to point out that this detector assembly is COMPLETELY repairable and should never be discarded. Here’s why:

1. If the capillary gets clogged:

• Unclog it or solder in a new one

2. If the heaters fail open:

• Replace the heaters

3. If the resettable fuse fails open:

• Replace the fuse

4. If the barrier window gets cracked/busted:

• Replace the window

5. If the temperature sensor goes bad:

• Replace it

6. If the reaction chamber leaks:

• Replace the bad seal (or both seals)

7. If a pin breaks off or a wire opens in the harness:

• Fix the harness

8. If the metal barrel rusts through (this has never happened, but there’s always a first time):

• Replace the housing

9. If the photosensor gets weak or dies completely:

• Replace the sensor

• This is the most challenging aspect as the OEM wants about $8000 for this chip; and, most of the time, it’s the barrier window that gets clouded/stained from the ozone- NO reaction; we don’t change out very many sensor chips.*

10. If the photosensor won't cool down to 1°C, it might be a bad Peltier section of the chip -or- most likely, it's a bad Darlington Pair power transistor (mounted on the aluminum divider panel).

Important: *We’ve been fixing about two of these per year for the past 20 years. Don't listen to the rumors that you can't procure a NGA-2000 CLD detector assembly, we can get them or repair them.*

Question 4

List of common CLD issues

cms_admin · Accepted Answer

1. The ozone lamp will die after many years of service

• but along the way, it will begin to decrease its ozone (O₃) production and you WILL experience Ozone Starvation (see other FAQ)

• The ozone lamp power supply might live long enough to power two or three lamps

2. The Darlington Pair power transistor that controls current to the sensor chip’s Peltier cooler will fail:

• sometimes the Peltier chip pulls too much current;

• sometimes a technician will unplug and re-plug the Darlington cable and blow the transistor (I’ve done this at least once);

• sometimes due to age

3. When reassembling, technicians can cause stress on the ACU02 (the CPU / controller board that sits on top of the BPR [backpressure regulator]) by not routing the ribbon cables neatly; this will break solder connections on some very sensitive chips causing hard failures (digital faults) or the very frustrating intermittent failures. 4. The capillary will foul, causing a loss of sensitivity. 5. The heaters in the reaction chamber are covered with thermite paste; the paste will dry out over time causing poor thermal conduction. This could induce an instability in the temperature control of the "block" (the upper region of the reaction chamber); and this could induce variations in zero, span, and process readings (sample analysis). 6. [later] 7. [later]

Question 5

How does the 400A work?

cms_admin · Accepted Answer

The 400A Flame Ionization Detector (FID) THC analyzer tests for the presence and concentration of HC compounds in a continuous gaseous sample by combining the sample with a fuel gas stream, ionizing the present hydrocarbons through combustion, and then measuring proportional charge produced by the presence of the ionized hydrocarbons in the sample.

Question 6

What is THC?

cms_admin · Accepted Answer

Total Hydrocarbon (THC) is a measurement of the hydrocarbon content (aggregated, not specific to an individual HC compound) concentration in a measured sample.
