Rosemount 848T
1-2
OVERVIEW
Transmitter The Rosemount 848T is optimal for process temperature measurement
because of its ability to simultaneously measure eight separate and
independent temperature points with one transmitter. Multiple temperature
sensor types may be connected to each 848T transmitter. In addition, the
848T can accept 4-20 mA inputs. The enhanced measurement capability of
the 848T allows it to communicate these variables to any F
OUNDATION
fieldbus host or configuration tool.
