2 STD700 Smart Pressure Transmitter
Description
The SmartLine family pressure transmitters are designed
around a high performance piezo-resistive sensor. This one
sensor actually integrates multiple sensors linking process
pressure measurement with on-board static pressure (DP
Models) and temperature compensation measurements.
Indication/Display Option
Standard LCD Display Features
o Modular (may be added or removed in the field)
o Supports HART protocol variant
o 0, 90,180, & 270 degree position adjustments
o Configurable (HART only) and standard (Pa, KPa,
MPa, KGcm2, Torr, ATM, inH2O, mH2O, bar, mbar,
inHG, FTH2O, mmH2O, mm HG, & psi) measurement
units.
o 2 Lines 6 digits PV (9.95H x 4.20W mm) 8 Characters
o Write protect Indication
o Built in Basic Device Configuration through Internal or
External Buttons – Range/Engineering Unit/Loop Test
/Loop Calibration/Zero /Span Setting
o Multiple language capabilities (EN, RU)
Diagnostics
SmartLine transmitters all offer digitally accessible
diagnostics which aid in providing advanced warning of
possible failure events minimizing unplanned shutdowns,
providing lower overall operational costs
System Integration
o SmartLine communications protocols all meet the most
current published standards for HART.
o All ST 700 units are Experion tested to provide the
highest level of compatibility assurance
Configuration Tools
External two button option for zero/span setting
Suitable for all electrical and environmental requirements,
SmartLine offers the ability to configure the transmitter and
display, for all basic parameters, via two externally
accessible buttons when a display option is
selected. Zero/span capabilities are also optionally available
via two external buttons with or without selection of the
display option.
Internal Two Button Configuration Option
The Standard display has two buttons that can be used for
Basic configuration such as re ranging, PV Engineering unit
setting, Zero/Span settings, Loop testing and calibration
functions
Hand Held 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.
Personal Computer Configuration
Field Device Manager (FDM) Software and FDM Express are
also available 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 intolerance 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.
