Honeywell ST 3000 pressure transmitters software upgrade

A software upgrade to the ST 3000 range of smart pressure transmitters that features enhanced on-board diagnostics to simplify maintenance by automatically telling plant personnel how the devices are functioning has been announced.

The upgrade includes diagnostics for both FOUNDATION Fieldbus and HART 5 and 6 networks. The standard HART 6 diagnostics include time-tracking functions - such as install date, calibration date, time-in-service and stress monitoring - and point value, meter body temperature and general reading functions. These functions allow plant personnel to diagnose problems from remote locations, be more aware of potential issues with individual transmitters, view a device’s history even after it has been removed from the process and conduct root-cause analysis.

All diagnostics automatically run when the transmitter is powered and the information can be fed directly into the plant’s distributed control system (DCS) and asset management solutions. The data can also be reviewed via a handheld device. Additionally, the information remains in the transmitter for use in troubleshooting activities, which means maintenance and reliability engineers no longer need to look for strip chart and historian data to begin failure review processes.
