2.1 Overview
This section discusses the considerations involved with deploying a Honeywell ST 800 SmartLine pressure
transmitter in a process system. The following areas are covered:
•
Safety
•
Input and output data
•
Reliability
•
Environmental limits
•
Installation considerations
•
Operation and maintenance
•
Repair and replacement
2.1.1 Accuracy
The ST 800 SmartLine pressure transmitter measures the gauge, differential, or absolute pressure of a
process and reports the measurement to a receiving device.
2.1.2 Diagnostic Messages
Transmitter standard diagnostics are reported in the two basic categories listed in
detected as critical diagnostics drive the analog output to the programmed burnout level. Problems
detected as non-critical diagnostics may affect performance without driving the analog output to the
programmed burnout level. Informational messages (not listed in
or setting conditions. The messages listed in
associated with HART and DE protocols. HART and DE diagnostic messages are listed and described in
the ST 800 SmartLine Pressure Transmitter HART/DE Option User Manual, #34-ST- 25-38.
