Smart pressure transmitter adds new graphic display capabilities aimed at improved operational efficiency

Honeywell’s new SmartLine pressure transmitters add new features designed to lower lifecycle costs and simplify communication.Honeywell has launched its new range of SmartLine industrial pressure transmitters, which aim to enhance communication abilities, improve operational efficiency, and reduce lifecycle costs for process manufacturers.

In industrial process plants, field devices that measure pressure, flow and level are used throughout the manufacturing process to support safe and efficient production. Large industrial complexes, such as those for refining crude oil, can have thousands of these devices to support their manufacturing processes.

Honeywell says its SmartLine pressure transmitters make it easier to support field devices and promote plant reliability with their efficiency-enhancing features, such as an on-board display capable of showing process data in graphical formats and communicating messages from the control room. This family of transmitters also features modular components to simplify field repairs and reduce inventory required to make those repairs.

“SmartLine is designed to provide the lowest total cost of ownership at every point in the project lifecycle to help customers’ operations be more efficient, their process more accurate and their plant more reliable,” said Don Maness, vice president of field products for Honeywell Process Solutions. “Honeywell introduced the first industrial smart transmitter in 1983 and has since supplied millions of smart transmitters around the world. To build on this legacy, our latest generation was designed with input from our customers and distributors.”

He adds that the display supports graphical process data in easy-to-read trend lines and bar graphs while also providing a unique platform for operator messages, comprehensive diagnostic warnings, and loop status for maintenance. These capabilities are part of the transmitter’s Smart Connection Suite, and allow control room operators to send messages to the display to make it easier and faster for field operators to identify the correct transmitter and determine required maintenance tasks. And, when integrated with Honeywell’s Experion Process Knowledge System (PKS), the transmitter can also display its maintenance mode – telling field operators if the control loop is in a safe state to perform maintenance. Even installation is made easier with this new display. Three buttons at the top of the transmitter are used with the graphic display to configure the transmitter completely with no external handheld devices required.

The modular design streamlines maintenance by allowing replacement of individual transmitter components instead of the entire unit, even in hazardous locations. This design reduces plant lifecycle costs by providing purchasing flexibility, lowering inventory costs and reducing maintenance and repair work.

“SmartLine offers a number of unique benefits to customers,” Maness said. “It exceeds industry norms for accuracy, response time, turndown and stability. It provides the lowest lifecycle cost by leveraging a modular design for configuration, installation, upgrades, and maintenance. It communicates to all automation systems through open communication protocol modules and is even more tightly integrated with Experion PKS and legacy DCS customers. Lastly, we designed it for the instrument technician to make it simple to configure with an easy-to-read display and without the need to use a field calibrator or to open the housing itself.”

Other safety and efficiency features include enhanced security alerts and wiring polarity insensitivity. Tamper reporting alerts the control room and records any change in the transmitters’ configuration or write-protection setting to allow operations to investigate any unauthorized access. SmartLine transmitters cannot be damaged by reversed wiring polarity and will function correctly if connected as such. This protection significantly helps during a plant startup, when time can be wasted locating and repairing incorrectly wired devices. Honeywell’s SmartLine pressure transmitters are available now.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
