Evaluate the site selected for the STT850 SmartLine Transmitter
installation with respect to the process system design
specifications and
Honeywell’s published performance characteristics for your
particular model. Some parameters that you may want to include in
your site evaluation are:
Environmental Conditions:
o Ambient Temperature
o Relative Humidity
Potential Noise Sources:
o Radio Frequency Interference (RFI)
o Electromagnetic Interference (EMI)
Vibration Sources

o Valve Cavitation
product display
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.
The display update rate may increase at cold temperature extremes,
but as with readability, normal updating resumes when temperatures
are within limits for full operability.
