Honeywell STG99L, STG19L User Manual

Addendum to

ST 3000 Smart Transmitter

Release 300 with HARTÒ 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.

Sub-Section Description of Change

In the left column of Table 4, under the heading
Gauge Pressure, add the information as
indicated by the highlights in Exhibit A, below.

(Note: Ranges for Ambient Temperature and
Process Interface Temperature are the same as
for other models in each series.)

In the row of Table 5 titled Gauge Pressure, add
the information as highlighted in Exhibit B, below.

At the right of Figure 40, under LGP Models,
references to Figure 48 have been added for
ST 3000 Transmitters STG19L and STG99L.

NOTE:

The use of Figure 48 (and corresponding Table

including Models STG19L and STG99L.

That is, the model number of the meter body is
specified on its nameplate.

In Figure 40, add the information highlighted in
Exhibit C in this addendum
