HART Commissioning
April 2017
HART Commissioning
How it works:
Two sensors are wired to a dual-input transmitter. The two sensors are measured in alternating fashion,
so when sensor 1 failure is detected, the transmitter can immediately switch the output to reflect the
sensor 2 value. The switch is automatic with no disruption to the analog output. The transmitter sends a
digital alert to inform the users that the Hot Backup feature is active and the primary sensor needs
investigation.
Take away: “The Hot Backup feature prevents primary sensor failure from disrupting process control.”
Target applications: Redundant measurements, critical measurements, trouble spots.
