Rosemount 3144P
FOUNDATION Fieldbus
Minimum and Maximum Temperature Tracking
Minimum and Maximum Temperature Tracking (Min/Max Tracking) can record
lifetime minimum and maximum temperatures with date and time stamps on
Rosemount 3144P F
OUNDATION fieldbus Temperature Transmitters. This
feature records values for Sensor 1, Sensor 2, differential and terminal (body)
temperatures. Min/Max Tracking only records temperature maxima and
minima obtained since the last reset, and is not a logging function.
To track maximum and minimum temperatures, Min/Max Tracking must be
enabled in the transducer function block using a Field Communicator, AMS, or
other communicator. While enabled, this feature allows for a reset of
information at any time, and all variables can be reset simultaneously.
Additionally, Sensor 1, Sensor 2, differential and terminal (body) temperature
minimum and maximum values may be reset individually. Once a particular
field has been reset, the previous values are overwritten.
