I don't know the equation, but I recall that our catalyst manufacturer (Cormetech) uses some form of equation involving some pretty nasty log functions, and it may be specific for each catalyst makeup and also proprietary. At any rate, given such an equation, you would most likely need to know...

We had a similar situation with equipment from Europe. Since the equipment was relatively new and our installation & start-up time was extremely limited, we opted to put several small 480/380 transformers in place with the thinking that as various components failed on down the road, we would...

We use a desuperheater to control steam sootblowers on some emission equipment. We ended up controlling the conditioned steam's pressure using the supply steam valve, and controlling the conditioned steam's temperature with the attemporator (water) valve, both with standard PID controls. The...

I believe there are several companies out there that have a VB-PLC communication interface. You might take a look at www.softwaretoolbox.com's INGEAR as one potential source.

We installed several 469 relays, about 25-30, in the 1998-99 time frame. We have experienced what I would consider to be a higher than acceptable failure rate on these units. It seems that there is a problem with the power supplies - that's what the repaired units come back with - but our...

Not clear on the question - are you asking for emissions monitoring systems or emissions control systems?

The quick-n-dirty way would be to put a MOV block immediately before the rung to be tested, moving a value into N7:4 or N7:10. By using a spare integer (N7:??) for the source data, you can then go into the data block and dynamically change the value that will be written into N7:4 or N7:10...

Well, I first posted this question in the 'Battery Engineering' forum, but no response after a week, so I figured I'd try another forum containing more members. Our insurance inspector voiced concerns over our recent installation of VRLA batteries, and suggested a capacity test even though...

Our insurance inspector voiced concerns over our recent installation of VRLA batteries, and suggested a capacity test even though the batteries are less than one year old. This is our first VRLA set on the larger systems (2000 Amp-hour) - capacity tests are currently scheduled for our Lead-Acid...

I don't know of any issues with mill operation. Relating to our feeders, the thing I would be concerned about is sufficient cooling for the motors if they are running off a Variable Frequency Drive. Lower RPM = lower cooling fan speeds.

You can get most manuals for Allen-Bradley equipment from their website http://www.ab.com

I would think the main advantage to the switch would be the availability and lower cost of 12V replacement parts along with the ability to add 12V accessories. I'm guessing that 6V systems went out of favor in the late 50s?
