Honeywell (NYSE:HON) today announced enhancements to its popular STT250 temperature transmitter, which is ideal for control and safety temperature measurement applications.

The new STT250 features include advanced diagnostics, which allow employees at every level of plant operations to proactively manage the health of their field devices to prevent failures before they occur, while at the same time reducing plant down-time due to unscheduled repairs. Maintenance teams can also use the advanced diagnostic information stored on the transmitter to allocate maintenance resources more effectively, while plant engineers can use on-board transmitter and sensor information for more accurate process analysis, leading to greater plant efficiency.

All HART variants of the STT250 are also compatible with the HART 6 open standard, allowing for an even greater level of device health monitoring. The new transmitters also support other open standards, such as the Electronic Device Description Language (EDDL) or certified Device Type Manager files, for fast startup and commissioning.

"Many of our customers have told us they want to improve interoperability between their field devices and host systems. This coordination helps them get the right data they need to better manage their assets, optimize their plant and lower their total cost of ownership," said Anand Krishna, Marketing Director, Honeywell Process Solutions. "Now that the STT250 temperature transmitter has wider support for open standards and advanced diagnostics information, it can help them achieve these goals by boosting both interoperability and flexibility."

The STT250 also features TUV SIL2 safety certification, allowing use with safety applications that require hot backups. For more information on the STT250 smart temperature transmitter, please visit
