Calibration Gas & Purge Control Panel

iGA Bespoke Panels SDC Sample Purge Control DSC 8659 rotatedcropped

Gas control panels may handle only calibration gas or may handle other functions too; in this case, bell sample purge control and bladder sample receipt.

The control unit is generally operated by Fathom or 3rd party PLC in conjunction with the HMCS and iGA system to put the correct sample gas or gasses online to an iGA rack.  A key switch permits a technician to take manual control of the iGA components associated with that panel and notify the HMCS system the components are under manual control.

Whilst the Fathom iGA system will generally be supplied with calibration gas makeup information via the central network, the white Traffolyte labels are used to note the gas values as an aid to the technicians.
