It is true that the OEM has discontinued sales and support for these analyzers … however, they are still VERY viable!! As long as there is a vendor that can supply photocells, source lamps, and miscellaneous other parts, you should be able to count on your Rosemount/Beckman paramagnetic oxygen analyzer for decades to come. Yes, decades! As long as you (or your technicians) don’t over-pressurize or overflow the actual detector (dumb-bell assembly) then you should expect many, many years of service.
Typical failures that we see in our depot include:
· blown thermal fuses,
· bad power supply circuits,
· wrong heater setpoints,
· bad fans,
· bad analog (or digital) meters,
· bad 4-20 mADC boards, and
· sometimes blown detectors.
With the exception of the “blown detector” issue, RIGAS can repair everything else!!
So what if you do blow up your detector? Well, for about $6500, RIGAS can install a new, better, more accurate, and more reliable paramagnetic detector. It’s actually an approved factory upgrade; the old Anaheim detector (formerly produced at the Rosemount facility in Anaheim, CA) is removed and a ‘buy out’ detector is installed in its place. This newer detector is much more forgiving of excess flow or excess pressure events; plus it’s more accurate and less noisy. You’ll need to wrestle with the cost though. We believe that it’s right at a cutoff point where a brand new analyzer should be considered. So let’s weigh the pros and cons:
 it will look and feel like the old analyzer so re-training is minimal,
 it’s still 100% Beckman/Rosemount and supported by RIGAS,
 there’s no labor time required to redo the panel cutout, plumbing, wiring, MOCs, etc, etc. (that just might be the savings that justifies keeping the old unit!!)
[a] it is an old analyzer with aging capacitors that are drying out … it will require some servicing before a brand new analyzer might require servicing … capacitors are easy to replace,
[b] cost of this new detector is high but it might be well worth it if you only end up spending $7000 to save the purchase price of a new analyzer at $20,000.
