Provides information about the level gauge system and alerts
users when periodic procedures are due.
Sets the current loop mA output to 2 mA or 22 mA when the
detector outputs 0 counts.
The process alarm lets the relay output trip when the process
level is above (high limit) or below (low limit) a setpoint.
Distinctly changes the current loop mA output in response to a
marked increase in the radiation field. This prevents control
problems when external radiographic sources are in the area for
vessel inspections.
