Intelligent analyzers: New Rosemount model offers HART, Profibus DP

Digital protocols add to versatility and functionality of analyzer family.


Emerson Process Management
has announced two new versions of its Rosemount Analytical Model 1056 analyzer, offering digital communication via two common protocols, HART and Profibus DP.

The new model 1056-HT and 1056-DP 4-wire, dual-input analyzers include complete digital communications capability for full operations and maintenance advantages in plants using the digital protocols. The company says the HART-enabled analyzer allows remote calibration, continuous monitoring of four live process variables, and configuration from Emerson's AMS Suite or DeltaV host application, legacy DCS, or SCADA system. The full complement of diagnostics allows plants to estimate the life of in-process sensors and perform required maintenance on a timely basis.

The model 1056 is a multiparameter instrument allowing single or dual inputs in any combination of pH/ORP/ISE, resistivity/conductivity, percent concentration, chlorine, oxygen, ozone, temperature, turbidity, pulse flow and 4-20 mA current input. The instrument has a large display and intuitive menu screens with advanced diagnostics and help screens, designed for ease of use. Modular boards, removable connectors, and easy-to-wire power, sensors and analog outputs simplify installation, including seven languages for user menus.

"The new Model 1056-HT and 1056-DP complete our digital communications offering," says John Wright, vice president of marketing. "Our customers can now select this easy-to-use multiparameter workhorse instrument for any liquid analytical application and leverage two of the most popular digital communications protocols available on the market. We're responding to demand for digital communications worldwide from end-users and OEMs in our extension of this immensely popular instrument."

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.
