Addendum to
ST 3000 Smart Transmitter
Release 300 with HART
Ò
Communications Option
User Manual 34-ST-25-17A
Overview
Two new models have been added to the family of ST3000 Smart
Transmitters:
Gauge Pressure Model STG19L
Gauge Pressure Model STG99L.
Each of these has an Upper Range Limit (URL) of 10000 psi (690 bar),
which is significantly higher than previously available models. Also, each
of these new models has significantly higher ratings for Maximum
Working Pressure (10000 psi, or 690 bar) and Overpressure (15000 psi, or
1034 bar). The burst pressure is rated at 26000 psi (1793 bar).
Except for the higher operating range, each of these two new models
includes physical and functional features similar to those of closely related
family members (STG1xL and STG9xL). With the exceptions noted in
this addendum, all parts of User Manual 34-ST-25-17A apply to these
new models.
Because of the similarities between new and existing models, these new
devices can be used as direct replacements in circumstances that require
higher pressure capabilities.
Details of pressure ranges for these new models are specified in
“
Additions and Changes to the Manual”, below.
