1. Introduction
1.1 About the ST 700 FF Pressure Transmitter
The newly designed Honeywell ST 700 is a smart pressure transmitter that has a wide
range of additional features along with supporting the FOUNDATION
TM
Fieldbus (FF)
communication protocol. The ST 700 pressure transmitter with FF protocol provides a
FOUNDATION
TM
Fieldbus interface to operate in a compatible distributed Fieldbus
system. The transmitter includes FOUNDATION
TM
Fieldbus electronics for operating in a
31.25 Kbit/s Fieldbus network and can interoperate with any FOUNDATION
TM
Fieldbus
registered device.
The STD700 is a high performance pressure transmitter featuring Piezo-resistive sensor
technology. By combining differential pressure sensing with on-chip static and temperature
compensation, the STD700 offers high accuracy and stability over a wide range of
application pressures and temperatures. The STG700 and STA700 are high performance
pressure transmitters featuring Piezo-resistive sensor technology combining pressure
sensing with on-chip temperature compensation capabilities providing high accuracy,
stability and performance over a wide range of application pressures and temperatures.
The SmartLine family is also fully tested and compliant with Experion ® PKS providing
the highest level of compatibility assurance and integration capabilities. The ST 700 easily
meets the most demanding application needs for pressure measurement applications. This
transmitter is used in the process automation industry for sensing and transmitting pressure
over intelligent communication networks.
The transmitter comes in a variety of models for measurement applications involving one
of these basic types of pressure:
• Differential Pressure (DP)
• Gauge Pressure (GP)
• Absolute Pressure (AP)
