Commercial
Bargraphs
Commercial
bargraphs are designed for use in non-nuclear
environments. They may be used as HI-LO, on/off,
or differential gap controllers and/or annunciators
in process or other control applications. Fully
programmable, these are the preferred choice for
new applications, or for replacement of set point
controllers, switchboard meters, other common
size indicators.
Nuclear-Rated
Bargraphs
Class I (1E) and Class II (seismic only) nuclear-rated
bargraphs are functionally identical to their
commercially-rated counterparts but they include
the following:
- Software
for the Class I bargraphs has been verified
and validated (V&V) to IEEE-7.4.3.2, 1993
standards
- EMI/RFI
testing has been performed to current Nuclear
Utility requirements
- Mild-environment
qualification to IEEE-323-1983 and IEEE-344-1987
