Dixson Nuclear Qualified Bargraph Indicators
AMETEK Dixson “PRO” (PROgrammable) Series bargraphs are the preferred choice
for new applications, or for replacement of switchboard meters, other common
size indicators, and setpoint controllers. The “PRO” Series is feature-enhanced,
and options are available to solve most common application problems.
Our nuclear-qualified bargraphs carry Class I (1E) or Class II (seismic
only) levels of qualification for all control room applications.
Class I (1E)
Includes all safety-related control loops and their various components
(models SA101P, SA202P, SH101P, SH202P, SN101P, and SN202P).
Class II (seismic only)
Includes all instruments mounted in close proximity to any Class I component.
If a component becomes detached from its mounting such that it could fall
onto Class I components, then that component must meet the requirements
of a Class II component (models BA101P, BA202P, BH101P, BH202P, BN101,
and BN202P).
