Configuration Tools

Integral Three Button Configuration Option

Suitable for all electrical and environmental requirements,

SmartLine offers the ability to configure the transmitter and

display via three externally accessible buttons when either

display option is selected. Zero/span capabilities are also

optionally available via these buttons with or without

selection of a display option.

Handheld Configuration

SmartLine transmitters feature two-way communication and

configuration capability between the operator and the

transmitter. All Honeywell transmitters are designed and

tested for compliance with the offered communication

protocols and are designed to operate with any standards

compliant handheld configuration device, such as Honeywell

Versatilis Configurator.

Personal Computer Configuration

On a personal computer or laptop, Honeywell Field Device

Manager (FDM) Software and FDM Express can be used for

managing HART device configurations.

Modular Design

To help contain maintenance & inventory costs, all ST 700

transmitters are modular in design supporting the user's

ability to replace meter bodies, standard displays or

electronic modules without affecting overall performance.

Each meter body is uniquely characterized to provide in

tolerance performance over a wide range of application

variations in temperature and pressure.

Modular Features

• Meter body replacement

• Add or remove standard displays

• Add or remove lightning protection (terminal connection) With no performance effects, Honeywell's unique modularity results in lower inventory needs and lower overall operating costs.
