KEY |
DESCRIPTION |
|
CDA |
Clean, dry
air. Compressed
air supply that has been filtered of particulate and moisture. |
|
FG |
Forming gas, a
mixture of H2
and N2
gasses usually with 4% H2 or less in the mixture. |
|
H2 |
Hydrogen gas; a
concentration > 8% in air is considered explosive. For concentrations
higher than 4%, FurnacePros requires inclusion of the Hydrogen Operation
(HO) option to safely use hydrogen as a process gas in a furnace. |
|
IO |
Input/Output signals
as an aggregate. IO is comprised of signals from one or more of these
sources: AI (analog input), AO (analog output), DI (digital input), or
DO (digital output). |
|
N2 |
Nitrogen gas. Inert.
Usually used to displace oxygen from the furnace during processing. The
Oxygen Analyzer (OA) option can be used with our automatic sampling
system to continually monitor O2
(oxygen) levels present in any of 3 zones in a furnace, displaying
results on the OI and alerting and alarming when detecting levels above
pre-set limits. |
|
PID |
Proportional,
integral derivative control loop that calculates an output to correct
the error between a measured process temperature and a desired set point
temperature. |
