Experion 1.2.1 Physical Characteristics As shown in Figure 1, the ST 700 is packaged in two major assemblies: the Electronics Housing and the Meter Body. The elements in the Electronic Housing respond to setup commands and execute the software and protocol for the different pressure measurement types. Figure 2 shows the assemblies in the Electronics Housing with available options.
Honeywell Multi-Communication (MC) Toolkit (not supplied with the Transmitter) can facilitate setup and adjustment procedures. Certain adjustments can be made through an Experion Station or a Universal Station if the Transmitter is digitally integrated with Honeywell’s Experion or TPS/TDC 3000 control system.
1.5 Transmitter Adjustments Zero and Span adjustments are possible in ST 700 SmartLine Pressure Transmitters with the optional three-button assembly located at the top of the Electronic Housing (see Figure 2). You can also use the Honeywell MC Toolkit or other third-party hand-held zero to make any adjustments to an ST 700 SmartLine Pressure Transmitter.

2.2 Safety 2.2.1 Safety Integrity Level (SIL) The ST 700 is intended to achieve sufficient integrity against systematic errors by the manufacturer’s design. A Safety Instrumented Function (SIF) designed with this product must not be used at a SIL level higher than the statement, without “prior use” justification by the end user or diverse technology redundancy in the design.
3 Installation and Startup 3.1 Installation Site Evaluation Evaluate the site selected for the ST 700 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: •...
Transmitter models, except flush mounts and those with integral flanges, can be attached to a two- inch (50 millimeter) vertical or horizontal pipe using Honeywell’s optional angle or flat mounting bracket; alternately you can use your own bracket. Flush-mount models are attached directly to a process pipe or tank by a one-inch weld nipple.
