INSTALLATION
Evaluate the site selected for the Transmitter installation with respect to the process
sys
tem design specifications and Honeywell’s published performance characteristics
for your particular model.
Temperature extremes can affect display quality. The display can become unreadable
at temperature extremes; however, this is only a temporary condition. The display will
again be readable when temperatures return to within operable limits.
FEATURES AND OPTIONS
The STT750 is packaged in one major assembly: the Electronics Housing.
The elements in the Electronic Housing are connected to the process sensors,
measure the process variables, respond to setup commands and execute the software
and protocol for the different temperature measurement types.
Figure 1
shows the
assemblies in the Electronics Housing with available options.

The Transmitter measures process Temperature and outputs a signal proportional to
the measured process variable (PV), including 4 to 20mA.
An optional 3-button assembly is located under the nameplate and provides a user
interface and operation capability without opening the transmitter to set up and make
adjustments to the Transmitter.
