Pressure transmitter supports HART 6

July 2007 Pressure Measurement & Control

In June, Honeywell announced that its ST 3000 Pressure Transmitter line is the process industries' first to support HART 6, the HART Communication Foundation's latest digital communication protocol. The new interoperability gives manufacturers a wider range of pressure transmitter options for measurement applications.

Additionally, the ST 3000 pressure transmitters can be more easily integrated with Honeywell's process information technology, Experion Process Knowledge System (PKS). The Experion distributed control system (DCS) supports HART 6 without any add-on devices or conversion tools. According to Honeywell, integrating Experion with the ST 3000 line offers faster transmitter start-up and commissioning, and better status indicators using HART 6 extended device status for predictive maintenance, among other benefits.

"Better interoperability means better information can be fed to process operators," said Revathi Advaithi, vice president for Honeywell Field Solutions. "The HART 6 protocol offers rich data that can be directly used in control strategies. This makes for a less-complex control system, tighter integration between control strategies and their associated field instruments, more process insight and, ultimately, better decision making in the control room."

The ST 3000 series includes absolute-pressure, differential-pressure, gauge-pressure, flange-mount, high-temperature gauge and in-line gauge pressure transmitters. Each provides accurate, reliable and repeatable pressure, level and flow measurement for applications ranging from hydrostatic tank gauging to measurement in boilers, fuel feeds and high-pressure reaction vessels.
