[Dsg-rtpc] DMS to RTPC pressure specification

[Marc Mcmullen]

Hi Sebastian,

DSG has completed connections to the valve panel as specified by the drawings George has provided. We have been running some functionality tests to ensure the controls software is reading and controlling the instrumentation properly.

The BONuS 6 detector is not connected to the system.

During testing we have discovered an issue with the current differential pressure transducer, as it does not have the proper ranger for the set up.


The full scale range of this transducer (MKS 226a) is ± 200 Torr (± ~107.048 iwc).

The EEL RTPC bubbler is set to ~0.1 (iwc).

The accuracy of this 226a is ± 0.53524 (iwc).

Currently, any measurement we read is within the bounds of the accuracy. Could you please provide a pressure differential specification between the DMS and RTPC (what is expected and what would be extreme). We can then source a suitable component.

 You may also wish to consider adding another absolute pressure transducer to provide the actual DMS pressure.

Thanks,
Marc
