The Vitiated Cone is an apparatus which burns samples in a reduced oxygen atmosphere to measure the following parameters:
The cone is the instrument described in ISO 5660-1, and is taken from the FTT Standard Cone.
This is achieved in this instrument by controlling the total volume of atmosphere fed into the chamber.
The instrument requires the following components:
The system will be calibrated without gas supply to the enclosure, and with the door open.
Meeting 02/01/24 - JM, CS
Idea was raised for replacing the rack with a control box based in a schroff bin - two designs consisting of 1 standalone system, and 1 system to be used interchangeably with a cone.
Current rack design with a cone means that the touchscreen is impractical to use - if the touchscreen was only used once, then practicality improves, but not by much.
Idea was raised for placing the gas system on a baseplate that will mount within a rack and a control box - this futureproofs the system.
Jim will look at the following:
CS To do:
Will update plumbing:
Option for splitter - will try another variant with a T
Plate area was 600x600mm which is the size of the rack top and not its internal base size of 450x450 - I have replumbed the plate as below
there is a T that feeds into the total mass flow with a very short line which I think will be okay - I am unsure how affected the MFCs are by turbulence, and there is not a lot of pipe where the O2 and N2 to mix.
Issue to document design and manufacture of the Vitiated Cone product.
