[Dsg-rtpc] [Dsg-internal] RTPC gas monitoring estimate

[Marc Mcmullen]

Hi Carlos,

Thanks for responding. The excel file was presented in our initial meeting (in the DSG control room) just to give an estimate of what was needed, based on a detector with some similar requirements (MVTs gas mixing system). There is an email from 1/23, where we identified what may be needed to actual supply gas and monitor based on George's preliminary design. That email has a more refined estimate attached, which is were DSG specified the NI9219 module, which you have already purchased. This is the major cost component, which requires the most lead time. So, there should be no problems, but we will make sure.

I have attached that list, please review it to see if you have already purchased any of the other items in the Controls Component section. These items would be the power supplies, connectors, and a chassis. If you have purchased them, let us know. If not, also let us know. In either case we will reevaluate the list at the meeting to see if anything else is needed.

But there are no problems!

Thanks,
Marc

Hi Marc,


I have to say that it is the first time I see this excel file. From this list, I purchased the NI9219 as was indicated in the email (to the maillist) fromThu 3/22/2018, the rest from the excel file no, because as I mentioned, I never saw that file or got the request to purchase it.


About the rest of components which I THINK need to be controlled (I could be wrong) and I have (or will have):

- MKS Mass Flow Controller Model GE50A013202SBV020

- MKS Differential Pressure Sensor Model 226A22TBBBBFB4A1

- MKS Absolute Pressure (Baratron, reused from old panel)

- Honeywell Absolute Transducer 19mm series Model 19C015PA4K (I just ordered yesterday)


then we have to register the temperature from the sensor you gave me some months ago. I have nothing else.


I hope that it won't cause any problems


Cheers


-Carlos

Hi Carlos,


Narbe has informed me that you have purchased some or all of the recommended equipment from the cost estimate, please let me know what you have purchased, and if you have all pressure transducers, temperature sensors, or any other instrumentation which will need to be in the display.


Thanks,

Marc

Hi Marc,


William and Mary purchased those components. I'm only purchasing the computers needed from our end.

Hi Narbe,


Please let me know what equipment you have purchased from the cost estimate I sent back in April of 2017. Please include any transducers you already have for the gas set up.


Thanks,

Marc
